The northbound elevated train rattled to a screechy stop. The gate of the last car swung open. A sallow,

squinteyed passenger stepped to the rough planking of the old station platform. Starting toward the exit, he

The squinteyed man turned about. His gaze steadied after he had blinked. His lips formed a satisfied smile,

as he looked toward the south end of the deserted platform. It was early evening; the platform was dimly

lighted, for it was above the level of the avenue lights. The squinteyed man was barely able to discern a

The squinteyed man approached. As he neared the huddled figure, he noted that the fellow was half

Calmly, he clapped a hand upon the hunched shoulders. The huddled man snapped about with a snarl.

The mellow glow of a platform light revealed a pasty, tightlipped face. Cunning eyes gleamed; then dried

lips twisted in a grin. The huddled man had recognized the arrival. He whispered a hoarse greeting:

"Hello, Chip!" The squinteyed man puffed at his cigarette. Then: "You've spotted Koker's crew?"

"Yeah." "Chip" retained his grin. "Lamp 'em yourself, Squint. They're parked in a sedan down in front of that

"All right, then. Let's hop along, before another train shows up. Koker and his outfit can stay where they are."

"Squint" led the way, with Chip following like an obedient dog. They walked to the exit and descended the

steps. This course brought them to the side street, a dozen yards from the corner. But instead of turning back

toward the avenue, Squint moved along the side street. Chip followed, puzzled. Squint explained.

"Koker don't know the lay," informed Squint. "He's not in on it at all. I just told him to be on the avenue, in

"I'm following the orders that came from The Head. Listen again, Chip; Koker isn't wise to the racket. So

They had reached the depressed entrance to a sidestreet tea room. Shuttered windows told that the place was

no longer in business. A weatherbeaten sign proclaimed the name: "THE YELLOW PARROT," with a

picture of the bird in question. Squint drew Chip down to the closed doorway. He began to work at the lock

OF the many characters in Manhattan's underworld, Squint Proddock and Chip Mulley were unique. Each

was a specialist in his own direction; each was wise enough to admit his own limitations.

Squint Proddock was an exracketeer who had feigned retirement in order to turn to other crime. His shifty,

blinking eyes had given him his nickname; they also rendered him easy to identify, which was the chief

Chip Mulley also carried a descriptive title. Originally, his pals had dubbed him "Chipmunk," a title that

befitted his dryish, smalllipped face. His nickname had been shortened to Chip; and he was known as a

competent subordinate who served various bigshots. Chip Mulley was an able hand at gaining needed

information. He was a competent gobetween, who kept what he knew to himself. It was not surprising that

The door of the Yellow Parrot had opened under Squint's manipulation with the skeleton key. The two men

edged into the tea room and closed the door behind them. Squint clicked a flashlight and passed it to Chip to

hold. Under the glare, Squint produced an envelope. From it, he took a typewritten sheet and studied a list

"That's the ticket, Squint! The Head knows his stuff. This ain't the first dope sheet I've lamped. I'm tellin' you,

"Come along, then." Holding the paper in his left hand, Squint took the flashlight with his right. "The next

They reached their objective. Squint focused the light upon the door and ordered Chip to open it. The

squirrelfaced hoodlum obeyed. Squint raised the schedule into the light, then growled:

"Unscrew the coat hooks on that crossboard. Then yank the board away. Make it snappy!"

Chip complied. After he had removed the hooks, the strip of wood came away. Chip issued an exclamation

when he saw the top edge of a low door. The other edges were obscured by a baseboard and upright corner

Again Chip followed Squint's order. The barrier slid easily. Squint's flashlight showed a narrow, darkened

The passage ran a dozen feet; then turned to the right. The two crooks followed it until they reached a

stairway. There, they ascended. They came to another barrier, which was held in place by screws. Squint

"Get busy," he ordered. "This is to be off by 7:25. You've got six minutes, Chip."

Four minutes were all that Chip required. Squint helped his aid to shift the blockade aside. They advanced

into a musty, windowless storeroom. Squint's flashlight showed heavy crates and packing cases, with

"It won't be locked," informed Squint. He blinked the flashlight for a final consultation of the dope sheet.

"We'll listen there, until we hear the buzzer. That comes next. I'll do the rest but stick with me, in case of

They moved to the door and waited there in darkness. Squint's hand was on the knob. They were ahead of

schedule; so the wait became prolonged. Then came the sound that the pair expected: a sharp, repeated buzz

Squint waited five full seconds; then turned the knob and pressed the door inward.

Chip saw a small, lighted office; at the right, a desk placed in front of a window that opened into an air shaft.

There was a door at the left of the room; straight across, a paneled wall that had a ledge and window like a

bank teller's wicket. There were no bars, however; the wicket was a solid wooden panel, which prevented

There was a man at the desk, a stoopshouldered, grayhaired fellow who had been going over an account

book. He was wearing a green eye shade, with rimless spectacles beneath. He had heard the summons of the

buzzer. Looking past Squint's shoulder, Chip saw the grayhaired man reach out and press a switch that was

That done, the grayhaired man arose. He turned toward the wicket. Hence his direction was away from the

two crooks who were watching him. It was obvious that the grayhaired man had admitted a visitor from a

front door on the avenue. He was going to open the wicket and meet the arrival. But he never accomplished

The grayhaired man had stopped long enough to stoop and turn the combination of a small safe directly

beneath the wicket ledge. Chip had not noticed the safe until that moment, for it was obscured in the

blackness beneath the ledge. As the door of the safe swung open, Squint stalked forward. Chip saw a

The grayhaired man heard Squint's approach. He started upward, too late. Squint snapped his wrist in artful

fashion. The blackjack thudded the grayhaired man behind the ear. Chip, bounding forward, saw the victim

"The white box," he whispered. "A tin one in the safe! Snag it, Chip! No noise!"

Chip found the box. He turned around to see Squint bending over the motionless body of the grayhaired

man. Withered fingers of the victim's left hand were clutching a small key that the man had drawn from his

pocket. Squint tugged the key from the victim's clutch. It came easily, for the hand had relaxed.

"Out again," whispered Squint, nodding as he saw the white box that Chip exhibited. "Speedy but no

THEY sneaked to the door of the storeroom. As they reached it, they heard a pounding at the wicket. Some

visitor had entered from the front. He was wondering why the wicket was not open.

Squint closed the door from the storeroom side. He polished the knob with a handkerchief. He and Chip

reached the stairway. Together, they shoved the barrier in place. Chip made quick work of replacing the

There, while Squint whispered hoarsely for speed, Chip put back the strip of wood and screwed in the coat

"Wait!" Squint's whisper stopped Chip. The flashlight glimmered downward. Again, Squint nudged it into

A gasp from Chip; a pleased chuckle from Squint. The interior of the tin box was filled with packets of crisp

"Fifty grand!" chortled Squint. "Easy pickings, eh, Chip? Come along. Let's scram. But take it easy when we

They made their exit to the street. Squint polished the doorknobs on both sides; but did not bother to lock the

barrier. Tucking the tin box under his coat, he urged Chip toward the nearest street lamp.

"We won't need Koker," whispered Squint. "The Head was right, Chip. It worked just like he expected it."

Chip's rejoinder was an uneasy one. They were just within the range of the street lamp.

"Instructions," responded Squint. "The last on the list. A signal. It means all jake."

He made a sidewise gesture with his left hand. Then, nudging Chip, Squint started eastward at a swift walk.

"A few blocks up," he said to Chip. "We'll take the crosstown subway. This was a pipe, Chip!"

CHIP nodded, as he looked back over his left shoulder. He saw a car which had been parked in darkness. It

was moving forward slowly, going back along the route which they had come, for this was a westward street.

Such was Chip's whispered comment. He had guessed the reason for Squint's signal. Koker's crew, on the

avenue, had been Squint's own idea. But a superman of crime, the hidden master of this night's doing, had

Crime after dark had been accomplished with ease and precision. The perpetrators were departing with their

swag fifty thousand dollars. All through the prearranged plan of an evil chief whom Chip Mulley had

Even Squint Proddock, though he termed himself a bigshot, had been no more than an instrument in the

JUST after Squint and Chip had made their departure by the side street, a stir took place upon the front

avenue near Casey's beanery. It began when an excited man came out from a doorway near the corner. Tall,

heavy of build, this man was attired in gray hat and overcoat. He was carrying a suitcase an empty one,

The man in gray spied a patrolman near the corner. He hurried up and spoke to the officer.

"Something something has happened!" stammered the man. "I'm afraid that there has been foul play!"

"In there." The man pointed to the doorway from which he had come. "That's where the trouble may be."

"No," he stated. "My name is Jennings, Luber Jennings, from Cleveland. Mr. Sautelle was to be in his office.

When I rang, he pressed the switch to let me enter. But when I reached the office, I couldn't rouse him."

They went to the door. It was latched. Jennings explained, nervously: "It swung shut when I came out. I tried

The patrolman looked dubious. But as he eyed Jennings more closely, he saw that the man's attire and bearing

marked him as respectable. The panels of the door were thin. The officer considered smashing one to reach

FROM down the street, men were watching. They were stationed in a parked sedan; the car that Chip had

spotted from the "L" platform. Beside the driver was a pastyfaced man who showed an ugly scowl. He was

"I'm watching him," growled Koker, interrupting the man at the wheel. "But it ain't the copper that counts

"I'm covering for a pal tonight," commented Koker. He referred to Squint Proddock, although he did not

mention the racketeer by name. "He's staging something hereabouts and I've got a hunch that it was in that

"Yeah!" Koker's tone was savage. "Him and the harness bull, too! He may have spilled the works to that

The chauffeur started the sedan forward. From the back seat, the barrel of a machine gun nudged into the

light. Murder was in the making. Neither Jennings nor the patrolman saw the death car that was looming

Across the avenue, a taxicab was rolling southward. Its driver had spied the sedan. So had a passenger in the

cab. A hissed whisper reached the driver's ears. It was a command. The taxi slowed, almost to a stop.

A door opened. A blackish shape sprang from the rear of the cab and landed beside an "L" pillar. The door

slammed shut. The taxi sped forward as if impelled by the jar. The driver was following instructions to get

The black being from the cab had timed his drop to a break in traffic. He sprang across the car tracks that ran

beneath the elevated pillars. He reached the opposite posts. His figure seemed to vanish as it stopped there.

The sedan was abreast the pillar where the cloaked form had halted. Twenty feet more would bring it to the

doorway where the patrolman had begun to bang at the panel, while Jennings stood beside him. Blue uniform

The growl came from Koker. In the back seat, the man on the right was guiding the machine gun, while the

one on the left was pressing a ready finger to the trigger. Another instant would mean double death.

Something thudded the running board, on the left of the sedan. A blackened figure had swooped from the

darkness beneath the elevated. Landing upon the moving car, the rescuer was just in time. A blackgloved

hand sledged through the opened window. The muzzle of a .45 automatic drove down upon the machine

Koker Hosch heard the crack. With a snarl, he twisted about. A revolver glittered in his fist. His lips mouthed

LIGHTS from across the street formed a background against which Koker saw his silhouetted foe. A cloaked

shape of blackness, with eyes that burned from beneath the brim of a slouch hat. The Shadow master

fighter whom all gangdom feared! He was the unexpected adversary who had knocked off Koker's machine

Viciously, Koker fired. Though the range was but a few feet, his shot went wide for the simple reason

Koker had aimed for the top half of the window, just behind the driver's head. That was where he had seen

The Shadow's eyes. But The Shadow had rolled backward, outward. Only his left hand clutched the lower

Koker howled the command as Pete, the driver, jammed the brakes. The order was to the man in the rear seat

the one beside the stunned machine gunner. Skibo lurched to the window at the left. He swung a vicious

The hand came up as Skibo's arm descended. Like a mechanical clamp, it caught the ruffian's wrist. Skibo's

head and shoulders shot through the window. The rowdy jammed there. Shifting his hold to the crook's neck,

With the move came a sinister laugh. It was a burst of fierce hilarity that spoke of doom for crooks. The laugh

Pete heard it. Wildly, the driver jolted the sedan forward. Skibo, though helpless, gave a frantic twist. The

Shadow's gun spoke; his bullet sizzed above Koker's ear, thanks to Skibo's disturbance of the aim. The

Shadow shifted outward; then suddenly dropped his hold and went rolling to the street.

In his haste, Pete had let the sedan swing from the curb. He was yanking the wheel to the right, to avoid an

elevated pillar. Pete had not designed the maneuver; purely through accident, it balked The Shadow. The left

running board was about to graze the pillar. The Shadow had dropped away just in time to save himself from

THE patrolman had heard the shots. He had yanked a revolver; from the doorway, he was opening fire at the

departing car. Skibo had rolled back into the rear seat. Koker, seeing no sign of The Shadow, had swung

The officer ducked into the doorway; but Jennings, out to the middle of the sidewalk, was rooted where he

stood. The sedan was making a left turn at the corner; Koker, leaning across, had gained a bead on Jennings.

But before Koker could press the trigger, a black shape hurtled up from the curb.

It was The Shadow. Gripping Jennings, he sent the man staggering against the patrolman in the doorway.

Falling away as Koker fired, the cloaked battler stabbed quick shots toward the escaping sedan.

An elevated pillar stopped a bullet that was designed for the sedan's gas tank. The Shadow dispatched a

second slug, this time with sure result. It pinged a rear tire just as the car was making its getaway, westward

Then began an amazing sequence. Traffic had deployed along the avenue, automobiles and trolleys stopping

in alarm at the gunfire. Halted near The Shadow was a taxi. It was not the cab in which he had come here; but

it was one that would suit his purpose, for it was pointed northward and nothing blocked its path.

The taxi was of the convertible type; its top was down, for the weather was mild. That was another advantage

for The Shadow. Leaping from the sidewalk, he whipped open the door and boarded the cab. The staring

driver saw his unexpected passenger; then shivered as he heard the commanding voice:

Mechanically, the taxi man obeyed. As the cab moved forward, another car crossed its path. This was a

roadster, that shot in from the right and turned left on the avenue. It was the same car that Chip had seen

As the taxi hurtled forward up the avenue, the roadster passed it, going down the other side of the broad

thoroughfare. There were many intervening pillars; and The Shadow, settling in the cab, had not spied the

roadster at the moment of its crossing. But those in the roadster saw The Shadow.

He was rising upon the rear seat of the taxi, ready when the driver swung left. From high above, he would be

able to deliver bullets above the driver's head, once he might spy the crippled sedan upon the side street.

Instantly, the roadster changed its course. Its driver yanked the wheel. The trim car made a turn in the middle

of the street, skidding between elevated pillars. It was a complete U turn, before the roadster reached the

blockade of stalled cars on the avenue. The roadster was on the trail of The Shadow!

First tokens of this new entrant came just before the taxi made the left turn at the corner. Shots rang out from

behind. The Shadow was a black shape towering up from the topless cab. He darted a quick glance down the

avenue. Two guns were belching from the very front of the pursuing roadster. Its windshield was down; the

The cab was negotiating the left turn, directly under the elevated station. For the moment, The Shadow was

protected from the fire in back. But a hoarse cry from the scared driver told that danger lay ahead.

"They're waiting for us!" It was true. From the crossing, the taxi man could see the sedan. It had halted on the

side street, fifty yards west of the corner. Halted, the car had swung across the street to block the

It was too late to avoid the turn. The cab, moreover, needed distance, to get away from the pursuing roadster.

The Shadow was trapped between two fires. With a competent driver, he could have counted upon mobility

in battle. But his chance hackie was frantic. Fear alone impelled the driver to follow a last command:

The hissed order came as the cab was directly in the center of the crossing. The driver stepped on the gas. The

cab leaped forward. Then a machine gun began to rattle from the blockading sedan.

At the same instant, the pursuing roadster whizzed into view from the pillars at the avenue. The taxi driver

saw the spurts of the machine gun. He glimpsed the lights of the roadster in his mirror. Wildly, he swung the

The Shadow was no longer in view. Apparently, he had dropped to the floor of the cab. Koker, Pete and

Skibo came piling forward, relying upon revolvers instead of the machine gun. They let the cab driver scurry

They reached the cab and leaped upon the running board just as the roadster arrived and swung up beside the

taxi. Glaring eyes looked from the roadster, as fists brandished guns. But the pursuing marksman and his

chauffeur were treated to the same astonishing sight as Koker Hosch and the latter's pals.

Weirdly, The Shadow had eluded the trap. Somehow, he had made a complete evanishment. He had rescued

Jennings and the patrolman from their dilemma; then had been forced into one of his own. But he was out of

SIRENS whined from the avenue. A snarl came from Koker. A fierce growl was given in the roadster by the

marksman who sat beside the driver. Police cars were arriving. Crooks had failed to get The Shadow; it was

The roadster hurtled forward. Its occupants had opportunity for a getaway and they took it. The speedy car

careened to the sidewalk and squeezed past the deserted sedan. The motor roared as the twoman car sped

Koker and his pals were left in a jam. A patrol car came whining from the blocked avenue behind them. They

turned to fight it out. Pete and Skibo opened fire. The police car halted; they sprang toward it, only to be

felled by prompt bullets. Koker saw a chance for flight. He leaped to the wheel of the abandoned taxi.

Copying the example of the roadster, Koker jolted the cab past his abandoned sedan; then whizzed away to

the west. The police car took up the chase. Pete and Skibo lay sprawled upon the street for others to pick up.

IT was after the street had cleared that a singular happening occurred at the crossing where the side street ran

beneath the elevated station. The superstructure there was low; a traffic light hung from the heavy girders that

A taxi happened to cross the avenue. Like the one that The Shadow had commandeered, this cab was

opentopped. It had no passengers; nevertheless, the driver was careful enough to slacken speed as he hit the

To the hackie's surprise, the rear springs gave a sudden thump. It worried him; but he kept on slowly and

decided that the cab was all right. Two blocks further on, he received another surprise. He was about to turn

left from the westbound street when a quiet voice spoke from the back of the cab.

Looking about, the taxi driver saw that he had a passenger. They were near bright lights; in their glow he

could see a tall, calmfaced personage riding in the car. The passenger was attired in evening clothes; he was

When and how this stranger had boarded the cab, the hackie could not guess. He removed his hat and

scratched his head; then reached over and pulled the metal flag to start the meter ticking.

A soft laugh came from the fixed lips of the mysterious passenger. The driver had not noticed folded

Only The Shadow knew the mystery of his own disappearance. Half an hour ago, he had ridden into a trap.

He had seen it while his commandeered cab was making that left swing beneath the low structure of the

elevated platform. The Shadow had given an order to his former taxi driver. Then he had sprung up from his

standing position in the rear seat. He had caught the nearest girder beneath the elevated. He had swung to

safety, a blackened, unseen shape, just before the roadster had whizzed leftward beneath him.

Thus had The Shadow changed the trap. He had known that the taxi driver would duck for safety. He had left

criminals to the law. The police themselves were to blame for the escape of the roadster and the taxi flight of

Safely ensconced above the crossing, The Shadow had retained his perch until after excitement had died.

Then he had waited for another opentopped cab. One had come along. He had taken it. He was riding

serenely toward Times Square. To his credit he could charge the rescue of two doomed men: Luber Jennings

Yet The Shadow's laugh lacked mirth, and with good reason. Men of crime had escaped him tonight. Because

of that, The Shadow could foresee new trouble. Not from Koker Hosch; The Shadow knew him to be nothing

The Shadow's concern involved the marksman who had ridden in the speedy roadster. That enemy, arrived so

timely, was one who impressed him. The Shadow could see the menace of a super foe one who had been

behind tonight's doings. More must be learned; for later, there would be new and bitter conflict.

The Shadow was right. Tonight's adventure had been but the preface to events that were due. Chance had

brought The Shadow into a game that would become the strangest epoch in all his warfare against crime.

It was dusk the next day. Two men were seated on opposite sides of an office desk. One was baldheaded,

bespectacled Wainwright Barth. Barth was acting police commissioner in the absence from New York of

He was Joe Cardona, crack ace detective of the New York force. Joe, at present, was an acting police

The air in the room held that electric quality that comes when two strongwilled men hold forth in argument.

Barth had been raking Joe over the coals about the stickup of Sautelle's wholesale clothing firm and the

street fight that followed. Cardona was restraining himself while the acting commissioner was pounding his

Barth roared out, "Two weeks ago a gold shipment, consigned to a bank, was landed from the steamship

Arabia, and robbed from under the very noses of the guards on the dock! And not a clue to the theft!

"Three nights ago another crime was perpetrated! Securities valued at one hundred thousand dollars were

stolen from the offices of Mullat Co. by a man who posed as the Chicago partner of the firm Herbert

"And now this Sautelle stickup, and the gun fray following! What have you found out, Cardona?"

Joe was uneasy. He wished Commissioner Weston were back, for Cardona understood Weston better than he

"We found out that Koker Hosch and a crew of gorillas were the ones who were in the sedan. Koker escaped,

but one of his men, dying in the street, blabbed that Koker was to cover the stickup at Sautelle's."

"About the gun fray," he remarked. "Who began it? Who prevented the murder of Jennings and the

"The Shadow!" he snorted. "More folderol, Cardona! Always The Shadow! When no other explanation seems

plausible, you invariably resort to that one! Fiddlesticks! I can no longer tolerate such absurd conclusions!

"I've made up my mind that these crimes are linked," he decided, "and I still insist they cannot be termed as

perfect ones. One link must be located; it may carry us along the chain. Find Koker Hosch, Cardona. Use

your own measures. Spare no effort! A roundup of all criminals, if necessary. For the next fortyeight

JOE CARDONA wore a pleased smile when he left the acting commissioner's office. For once, he had

arrived somewhere with Wainwright Barth. There was still a slim chance that Koker Hosch was in

Manhattan. If not, other clues might come within the stipulated time limit. A roundup, however, was not in

Cardona's plan. He preferred to utilize stool pigeons rather than the dragnet. Tipsters with information usually

proved more efficient than a mass movement of the law. The latter gave crooks a chance to take to cover.

Koker Hosch! That name would be whispered in the bad lands; and soon listeners would be on hand to hear

it. Stoolies might gain other tips as well. Cardona was inclined to Barth's theory, that these crimes were not

perfect. The fact that they were linked was a discovery that Joe put to his own credit.

THERE was one place on the East Side that Joe Cardona would have liked to visit in person. That was the

Hotel Spartan, a dingyfronted hangout where crooks of known repute were wont to congregate. A visit there

would have been a giveaway, however. As bad a move for stoolies as for Cardona himself.

The windows of the Spartan's lobby opened upon a sidewalk beneath an elevated railway. Boastful rowdies

those who had covered themselves too well for the law to pluck were among the strollers who went in and

out of the Hotel Spartan. Frequently, their conversation continued after they had reached the sidewalk.

This evening, two such men were speaking. Their words were plain as they sauntered to the street. A

wizenedfaced man was lounging outside the doorway. He caught a snatch of the conversation.

The speakers had passed. The wizenedfaced man waited a few minutes; then lighted a cigarette and shuffled

across beneath the elevated. His wise lips showed a grin. This unnoticed listener was a wellknown figure in

the bad lands. Thugs called him "Hawkeye," for he had the peculiar ability of seeing much that went on about

Last night, Hawkeye had learned that Koker Hosch was going on a coverup job. He had gained that

information as last minute news; and Hawkeye had passed the word along to a hidden chief: The Shadow.

There were dozens of characters like Koker Hosch, still in Manhattan smalltime leaders who could

summon a crew if needed. The question was which one to trail. Hawkeye had heard mention of "Hunk"

Long before Joe Cardona's stoolies would be about their tasks, this chance tip would be known to The

A bluish light was glowing upon the polished surface of a table. Beneath the glare, two hands were sliding

earphones toward the wall. Upon one finger of the left hand glimmered a resplendent fire opal. This jewel

The bluish light clicked off. Solid darkness pervaded the room. A cloak swished; lips formed a quivering

laugh. Then silence held within the blackened sanctum. The Shadow had received final reports from his

Instructions had gone across the private wire from the sanctum. Word to Burbank, The Shadow's contact

man. Detailed orders to be passed to roving aids. Crime was due tonight. Again, The Shadow had learned of a

NEAR Seventysecond Street, a huddled watcher was looking toward a lighted corner. It was Hawkeye,

covering an appointed spot. A taxi was cruising about the block. It was the same vehicle that The Shadow had

Parked elsewhere was a trim coupe, wherein a man sat low behind the wheel. This was Harry Vincent, most

capable of The Shadow's agents. He was in readiness for any signal. Harry was watching Hawkeye. He

strained as he saw a blot of blackness pause by the doorway where the wizenedfaced spotter crouched.

At the same instant, Hawkeye heard a whisper. Tensely, he listened. He knew that The Shadow had arrived.

"Instructions!" intoned the low voice. "Wait for Marsland. He will come by subway. Board the cab.

Hawkeye nodded, as blackness moved away. A blurred form took the momentary shape of a cloaked figure,

In his coupe, Harry Vincent heard the door open. A blackened form settled beside him. The door closed.

Many details had been learned regarding Hunk Lomus, even though that rowdy had not been spied. Hawkeye

had spotted members of Hunk's crew and had heard mention of two meeting places; first, a rendezvous at a

Tenth Avenue garage; later, a coming contact with a second car at this corner near Seventysecond Street.

Time had not been mentioned. The Shadow had ordered Cliff Marsland, another aid, to cover the garage.

Cliff had reported the arrival of four hoodlums and their plans for prompt departure. The Shadow had

calculated that nine o'clock would be the meeting hour of the two cars. Hunk Lomus would have two crews

upon the job. The Shadow, to combat him, would be present with a quartet of agents.

Tonight, The Shadow was banking upon Hunk Lomus to lead him unwittingly to a scene of coming crime.

Koker Hosch had served that turn last night; but belated news had cost The Shadow opportunity. He had

gained no time for a preliminary survey of the neighborhood. This time, matters would be different. The

Yet, at this very moment, events were brewing elsewhere. Chance was destined to play The Shadow false.

TEN blocks distant from the corner where The Shadow waited, two men were crouched in the gloom of a

One of the pair was Chip Mulley. Hoarsely, the roundshouldered crook was arguing matters with a bulky

"Listen, Moose," Chip was saying. "It ain't my business to tell you how to work this lay. But you've got the

"I'm waiting," growled "Moose." "Hunk Lomus is showing up to cover. He's taking the front like Koker did

"He might've. Koker wasn't needed. Havin' him there was Squint's idea. The Head didn't say to have Koker

"That's easy. Supposin' Hunk Lomus spills somethin' like sayin' he's a pal of Moose Sudling "

Moose Sudling grunted an affirmative. A pause. Then a flashlight shone, guarded, upon a sheet of paper in

"Yeah," decided Moose. "Sounds like you had the right idea, Chip. We'll let Hunk cover afterward. First

thing on the list is this guy Percy Rydler, who lives in the old house. You saw him leave?"

"Yeah. An hour ago. They had to load him in a taxi, out of a wheel chair. Sicklooking gazebo."

THE two moved through the passage, Moose lumbering in advance. They came to a basement door. Moose's

"A cinch!" whispered Moose. "The Head said it would work sure! How he got the key, I don't know. Ease the

Chip obeyed. Moose led the way to a flight of stairs. They ascended and stopped by a closed door. He ran the

flashlight along the right edge; then jabbed a knife blade into the crack. A spring clicked. Moose reached

farther down and repeated the operation. He moved to the left of the door and found two other springs.

"Some goofy automatic bolts," chuckled Moose. "They close from the other side. The Head gave me the dope

Moose opened the door. He and Chip stepped into a darkened kitchen. Moose found a flight of stairs. The

two ascended. They reached a hallway where a single light was burning. Moose whispered: "The rear room!

Moose moved forward and entered. Chip was a few paces behind. As he crossed the sill, he heard a sharp cry

from the other side. Then a hoarse snarl; followed by the noise of a sudden scuffle.

In the center of the rear room, two men were struggling. One was Moose Sudling, big and brawny, almost as

large as the doorway through which he had entered from the hall. The other fighter was a wiry, whitehaired

man who clutched a gun. Frantically, he was striking at Moose's head; while the huge ruffian, bobbing, was

The struggle ended before Chip could join. The old man gurgled helplessly as his last wild stroke missed his

adversary's skull. Moose drove the victim up against the wall. With one vicious heave, he battered the white

The old man sagged. Moose twisted the scrawny neck and gave another bashing stroke. He released his

clutch and let the victim sprawl. Methodically, he pulled a paper from his pocket and consulted new

Moose led the way into the middle room. The flashlight shone upon a portrait that adorned the wall. Moose

raised his left hand and pressed the gilt frame upward. A click sounded; the picture swung out upon a hinge.

Another glance at the dope sheet. Then Moose manipulated the knob. He opened the safe, found a long jewel

box and brought it beneath his light. The top of the box popped open. Chip gulped at sight of glimmering

"There's ice for you!" croaked Moose, approvingly. "The real McCoy! Like The Head said they'd be! You

"More like a hundred," he affirmed. "And you can leave it to The Head to get rid of them."

Moose closed the safe and turned the dial. Clumsily, he wiped away finger prints. He swung the picture shut

and mopped the lower frame. Followed by Chip, the big man moved back to the rear room. There he stopped

"Yeah." Again Moose mumbled. He fished out the paper from his pocket. "That means we gotta scram."

With disregard for silence, the pair made their way to the back stairs. They descended to the kitchen; then

down to the basement. Moose made final consultation of the dope sheet; then extinguished his light

"Leave the door open," he whispered, as they moved out into the rear passage. "Take it slow after we get to

Passing between silent buildings, they gained the rear thoroughfare. Like Squint the night before, Moose led

Chip toward a street lamp. There the big thug stopped and moved one hand up and down. That done, he urged

Looking over his shoulder as they turned, Chip spied the outline of a parked roadster. Some one in that car

had seen Moose's signal. The upanddown motion must have meant that something was wrong. Moose

The Head mysterious chief of crime had prepared for such a happening. That was why the waiting

roadster stood on duty. Measures would be taken to make up for Moose Sudling's blunder.

Again, burglary had been accomplished; this time it had produced murder. Moose Sudling's early action had

Double crime had been completed despite The Shadow's knowledge that evil had been due tonight.

AT the time when Moose Sudling and Chip Mulley were making their departure by the rear street, an

automobile was halting in front of the brownstone house that they had left. The car bore a Massachusetts

"This is the house," remarked man the beside the driver. "Are you sure you don't want to stop over, Jerry? It's

"I'll have to travel on, Hal," returned the driver. "Business appointments tomorrow. But I'm wondering if

you'll find any one home here. The house is dark. Maybe you'd better let me drive you to a hotel."

"Don't worry about me," laughed Hal. "I have a key to the place. My brother is always glad to have me stop

Hal Rydler stepped from the car. A street light showed his face to be a friendly one, smiling and

wellfeatured. A crop of lightbrown hair projected from beneath his sidetilted hat. Hal shook hands with

Humming to himself, Hal ascended the brownstone steps. This visit was not an unusual one. Often before,

Hal had dropped in to see his brother Percy. In fact, it was the frequency of his visits and the odd hours of

Today, in Baltimore, Hal had run into a friend, Jerry Lester, who was driving up to Boston. Hal had agreed to

accompany Jerry as far as New York. Another chance to see how Percy was; for Hal was concerned about his

sickly elder brother. Hal had left Baltimore before the afternoon mail delivery. Hence he had failed to receive

USING his key, Hal unlocked the front door and stepped into the lower hallway. All was silent in the old

house. Hal closed the front door quietly. He decided that Percy must be asleep; it would be unwise to awaken

him. The best plan would be a silent ascent to the guest room on the third floor.

Hal started up by the front stairway. He reached a landing; there he paused. A flashlight was blinking from

beyond a door that stood ajar. It was the door to the middle room on this floor. Hal noted a light from another

Something was wrong in the house. Hal's first worry concerned Percy. His brother occupied the front room.

A semiinvalid, he would be unable to protect himself against thugs or burglars. As the flashlight blinked

Just as he was about to enter the middle room, he heard a sound that stopped him. The noise was a peculiar

thump; it was repeated. Hal realized that he was listening to clumping footsteps. Some one had gone from the

A figure suddenly blocked the opposite doorway; then shouldered into the middle room and paused. Against

the light from the rear room, Hal could see the prowler. An instinctive dread seized him. He was staring at a

The man in the middle room was short and chunky. His form was almost like a square. Thick, bulky arms and

legs; a body that bulged like a barrel; hands encased in large, bigfingered gloves; and above the wide,

Sight of that visage made Hal Rydler remain where he was. One look had the same effect as if the young man

had heard a rattlesnake's warning. The venom that showed in the prowler's glare seemed beyond human

The face was large, longjowled and darkish. The nose was wide, with nostrils that spread with every breath.

The eyes were glaring balls that bulged from their sockets. They were topped with bushy brows; above them

loomed a high, broad forehead that was furrowed with Vlike wrinkles. Jetblack hair, shaggy and unkempt,

The monster was advancing, firm despite his clumsiness. Hal could hear fierce breathing that came from lips

which formed a twisted leer. He saw the lips move as if mumbling. As they grinned grotesquely, white teeth

shone like fangs. Horror held the watcher. Hal felt his knees quake, despite his efforts to fight down fear.

HAD this monstrous prowler kept on to the front doorway, Hal Rydler would have been paralyzed, unable to

offer battle. However, the chunky figure changed its course. Away from the outlined light, the glaring man

became no more than a square, wide shape that clumped with mechanical tread. He had turned toward the

A flashlight glimmered from one gloved hand. Staring toward the focused glow, Hal saw the hinged picture

on the wall. He watched the man's other hand press the panel. The picture swung out. The same hand turned

the dial of the wall safe. Thanks to the light, Hal could see every subsequent move.

The gloating creature took nothing from the safe. He simply used his free hand to polish the interior, using

his gloved fingers as a mop. The hand closed the safe, but did not lock it. The fingers simply swabbed the

The monstrous figure stamped toward the rear room. Hal noted that the man did not turn sharply. Instead, he

clumped in circling fashion and thus arrived at the doorway. Again, the light was partially blocked. Gauging,

A full three feet; yet the clumping man was less than five in height. Allowing for his large head, the rest of

his shape arms, body and legs were almost an actual square, that fitted Hal's first impression. That was

For Hal was sure that his brother's safe had been robbed; not by this monster, but by some one who had

preceded him. The squarebuilt fiend might furnish a clue, if captured. But Hal doubted his own ability to

That bulky body had given an impression of super strength. Hal feared, moreover, that the fiend was armed.

It was not until the creature had marched mechanically from view that Hal gained the nerve needed for

action. Despite the fact that he could not forget the venomous glare of the inhuman face, Hal steeled himself

The clumsy footsteps had faded when Hal reached the lighted door. The man had gone through the back room

to the hall. The thumping tread told that he was descending the back stairs. Hal gave a leap, intending to

overtake the monster. He knew that the fiend had not guessed that he was in the house. He saw opportunity in

pursuit and a surprise attack. But as he reached the center of the rear room, Hal stopped short, quivering.

A body was lying upon the floor, face downward. White hair was clotted with blood.

Hal knew old Jemley, the caretaker whom Percy hired to look after the house whenever he was absent.

Jemley here was proof that Percy was away. But relief over his brother's safety was lost with Hal's discovery

The question gripped Hal as he let Jemley's head and shoulders settle to the floor. Justice was what Hal

wanted against that fiend and all who might have served him. The house was stilled; yet it seemed charged

with the evil menace of the bestial figure that had just departed. Perhaps lurkers had remained here!

From downstairs, a clock was chiming nine. It was after that hour, Hal realized; for the old grandfather's

clock was always a few minutes slow. Much had happened in the short while that Hal had been here. Much

might happen yet, if he invoked the law. There was still a chance that the police could capture that

squareshaped fiend, particularly since the monster had not known of Hal's presence and might, therefore,

The telephone was in the front room; but Hal's worry about possible lurkers restrained him from using it. He

wanted to get out of the house at once; to take the front street to a lighted avenue. There he could find a

Rising, Hal crept from the death room and descended the front stairs. He opened the front door cautiously,

closed it behind him and sprang down the brownstone steps. Excitedly, he started for the nearest corner,

making long strides to increase his pace. Hal feared no danger; for he was sure that the clumpy fiend had

gone out by the back door. Hence he did not try to render himself inconspicuous.

A touring car was rolling slowly from the avenue. Hal saw its dimmed headlights approaching; but gave no

thought to them until the car suddenly shifted its direction. The lights brightened. Hal Rydler was caught in

the brilliant glare. The flood of illumination awoke his thoughts of danger. With a sharp cry, the young man

Guns barked. Spurts of flame stabbed from the interior of the car. Bullets ricocheted from sidewalk and steps.

The car lurched forward, to drive down upon its diving victim. New death was in the making. Hunk Lomus

had arrived with part of his coverup squad. Thugs were leaping from opened doors. Their plan was to blot

Then came another roar. A second car wheeled into view a coupe with a searchlight that clicked on as the

new machine approached. A fierce, weird laugh resounded with the echoes of the wild barrage that thugs had

Another combatant had arrived. One who had come to deal with men of crime. Again The Shadow was

The Shadow had delivered a timely stroke. He had chosen the right moment to open fire. Had he started battle

with the sound of the first barrage, Hunk Lomus and his men would have stayed within the shelter of their

car. As it was, all of them had leaped to the street, with the exception of Hunk himself. Those on the street

The Shadow had swung from the opened door of the coupe. His first cannonade began while he was riding

closer. But as he neared the snarling thugs, he dropped to the sidewalk. Directly beneath a glowing lamp, he

The Shadow had clipped the killer who was nearest to Hal Rydler. The other three had wheeled. Their

revolvers spoke as they saw The Shadow. Already, he was weaving from the light; for his purpose was

accomplished. He had drawn the fire from the intended victim. As The Shadow faded, his big guns blasted

Rooted thugs went sprawling, as they fired vainly. The Shadow's bullets found their marks. The slugs that

came in his direction were spattering all about. Only Hunk Lomus had a chance to fire unmolested. He was

Both were wide, for they were hurried and the touring car was moving. The bullets flattened against a

brownstone wall. Hunk might have found his target with a third shot; but he was interrupted. Harry Vincent

Cutting sharply, Harry jammed the coupe against the touring car. Hunk yanked the wheel to avoid a smash.

The front of the touring car jolted upward. The car tilted; then regained its balance on the sidewalk and

Hunk still gripped his revolver, though he had grabbed the wheel with both hands. Savagely, he swung to aim

for the driver of the coupe. Harry's car was at the left of Hunk's; and Harry had not drawn his own gun. But

As Hunk aimed, Harry kicked the left door open and rolled out to the street. He hit the asphalt with his

shoulder, came up with his left hand on the running board and drew an automatic with his right.

Hunk had started fire. His bullets were high. Harry thrust his gun upward and returned the shots. Entrenched

below the step of his own car, he had the advantage. Though he fired blindly, he scored a hit. A howl came

These events came as The Shadow finished fire. With them, a new glare bathed the street. Another car was

roaring from the corner. Revolver muzzles were bristling from its sides. Hunk's second crew was charging

FORGETTING Hunk Lomus, Harry Vincent turned. There, in the glare, he saw The Shadow, squarely in the

middle of the street. About the cloaked fighter lay the thugs whom he had downed. Crippled crooks were

crawling toward the curb. But The Shadow was faced with new enemies; and he had no time to head for

Harry aimed, to join The Shadow in what seemed hopeless resistance. The Shadow's automatics were already

booming. Harry aimed squarely for the lights ahead, just as The Shadow performed a sudden shift to the

right. Then the oncoming car skidded. Its right wheels jounced the curb. The car careened; then swung half

The Shadow had aimed for the side of the windshield. He had guessed that the car would be equipped with

shatterproof glass, so he had picked the edge of the opened front window. He had winged the driver. The

fellow had lost control; but had managed to apply the footbrake. The Shadow's hope had been to wreck the

The jouncing thugs had lost all chance at aim. One crook, unlimbering a machine gun, had half fallen from an

open door. Others were grabbing him; but they acted too late. The Shadow delivered a final shot. The

machine gunner took a headlong dive to the gutter and his weapon clattered with him.

New brakes screeched. A taxi had wheeled up behind the thugmanned car. Two fighters sprang from it:

Cliff and Hawkeye. They fired from the darkness of the street. Crooks leaped out to battle when they found

A man sprang suddenly from a spot across the street. It was Hal Rydler. He had seen Harry beside the coupe.

He knew that this fighter must be a friend. Harry beckoned Hal forward. He saw the rescued man stop short;

He had forgotten Hunk Lomus. Though wounded, the rogue was still capable of action. He had crawled from

the wheel of his own car. He had shifted into Harry's coupe. Gun in hand, Hunk had seen Hal coming. He

Harry made a grab for Hunk's right arm. As he nailed the wrist above the aiming hand, a shot roared from the

center of the street. Hunk's arm sagged in Harry's grip. The trigger finger pulled; the muzzle, dropping,

The Shadow, like Harry, had heard Hal's cry. Swinging about, the cloaked fighter had picked off Hunk while

Hal stumbled up to where Harry stood. A moment later, a machine wheeled forward. Moe Shrevnitz had

SIRENS were sounding, as a sequel to the cessation of gunfire. Shrill whistles could be heard from the

Harry heard The Shadow's voice hiss an order. The cloaked chief had arrived beside him. Nodding, Harry

shoved Hal Rydler into the taxi. Moe had opened the door in readiness. As Harry slammed it, the cab

Cliff and Hawkeye arrived. They heard The Shadow's next order. They sprang aboard with Harry. The coupe

followed the path that Moe had taken. The cab had already turned the corner when the coupe started. The

Shadow, silent, remained by Hunk's touring car and watched the coupe whizz from sight.

Sirens were closer. Their location was elusive; for they were coming from various directions. Listening, The

Shadow stepped close to the dark side of the touring car. He had spied a man rising from a spot across the

This hoodlum was still capable of battle; but The Shadow could easily have dropped him, for the man had not

seen the waiting figure in the darkness beside the car. Instead, The Shadow stood silent. He watched the thug

"Hunk!" The thug exclaimed the name hoarsely. He crouched beside Lomus. "Did De Shadow get you? Like

"Dis is Louie," persisted the stooping thug. "You can hear me, can't you, Hunk? Listen: de bulls is comin'; I

Hunk's head had raised feebly. He uttered a name that Louie repeated; but The Shadow did not hear it. A

police car had entered the street. The wail of a siren had drowned the spoken words. Then came Louie's

"I get it, Hunk. Sure I'll get aholt of Chip Mulley. I'll tell him you wanted me to pipe de word to "

Louie stopped before he again spoke the name that Hunk had previously uttered. The police car was bearing

down upon him. For the first time, he realized its closeness. Louie snarled and came to his feet. His left arm,

The police car had veered, to avoid a sprawled body. Its light had swung away from The Shadow. The

cloaked watcher raised an automatic, ready to drop Louie before the thug could fire. The Shadow's action

proved unnecessary. Revolvers tongued flame from the patrol car. Louie sprawled across Hunk's body.

Hunk Lomus had given his last gasp. Louie was coughing out his life as two officers sprang to the street.

The Shadow edged past the touring car. Rounding the back, he quickly gained a passage between two

darkened houses. He had reserved that outlet for a lastminute exit. It was time for prompt departure.

Running bluecoats were coming down the street. Other police were arriving in a second patrol car.

THOUGH The Shadow had lingered, he had experienced less trouble in departure than had his agents. Moe's

cab and Harry's coupe had been forced to run the gantlet of arriving police cars. Moe had swung into a side

street, to continue slowly; while Harry had sped along an avenue, to finally draw away from the police zone.

Moe had chosen canny flight because of his passenger. As he wheeled along the side street, he kept looking

in the mirror. He saw Hal Rydler deep in the rear seat, relaxing after the excitement. Moe grinned. He knew

that his passenger thought this cab was a chance one. Soon, Moe would circuit to the corner back near

But as Moe swung out to an avenue, he saw an approaching patrol car. He knew at once that he would be

questioned, if he stopped. Moe stepped on the gas and roared down another street. He heard shots behind

him; but they were no more annoying than a flock of mosquitoes. Moe was a smart driver. He expected to

Zipping through another side street, Moe suddenly jammed the brakes. Straight ahead, he saw a blockade.

The street was under construction. Moe turned about. Regardless of the curb, he backed the cab clear up on

the sidewalk and thumped a house wall. Then he jolted forward, reached a corner and whirled right, just as

More twists and turns. Moe paid no attention to the mirror. He was dodging out of the region where too many

questions might be asked. He grinned, as he arrived close to the corner where he expected The Shadow to be.

Recalling circumstances, Moe remembered how and where the man must have departed: at the blockade,

when Moe had backed the car upon the sidewalk. That was where the rescued man had decided to decamp.

Moe winced as he heard The Shadow's fierce whisper. Disgruntled, he told his story. He had not even talked

to the rescued man. He did not know the fellow's name; nor where he wanted to go.

Moe drove away, sluggish and dejected. The Shadow remained, his tall form barely discernible in the dull

light of the street. A mirthless whisper came from his hidden lips. The Shadow had wanted to talk with Hal

Rydler; to learn the man's name and all that he could furnish in the way of clues. That chance was gone.

Again, The Shadow had lost an opportunity to gain a lead to the actual crime which an outside crew had

Yet The Shadow had found one lone clue; and he was banking on it. He had heard the mention of a name:

Chip Mulley. Before long, The Shadow would find the owner of that name. Then would his trail begin.

Twentyfour hours had passed. The bad lands were agog. Late news of crime had created a huge stir in the

underworld. The grapevine was alive with rumors. So many tales had passed along the invisible telegraph

Boiled down, the facts were simple. A job had been done at the home of Percy Rydler. Diamonds, valued at

one hundred thousand dollars, were missing. Burglars had found a way in; they had opened a safe to take the

It was murder. More serious than other recent robberies. Yet the law was as baffled as before. Percy Rydler

had gone on a cruise ship. Contacted by radio, he had sent back word that doubled the bewilderment. He

could not imagine how the crooks had learned of the gems, or had gained the combination.

There had been a battle after the burglary. That news, particularly, concerned the underworld. Hunk Lomus,

like Koker Hosch, had found trouble. But Hunk had not escaped in Koker's fashion. Hunk had taken the

The dreaded name was whispered everywhere. Gangland feared the menace of its greatest scourge. Some

smooth supercrook was staging cunning crimes; The Shadow had as yet been unable to forestall that

mastermind of evil. But in the meantime, The Shadow was roving wide, picking off lesser rogues in an

That was the question that puzzled scumland. It produced vague theories throughout the underworld. Four

major crimes had been accomplished by a hidden perpetrator: the gold snatched from the steamship Arabia;

the securities stolen from Mullat Co.; the money grabbed from Sautelle's secluded office, and, finally, last

A crime master had amassed a harvest, without leaving a single clue. Unquestionably, he had gained his

spoils through the aid of competent workers. Every crime bore the earmarks of an underworld job. But who

None could give the answer. Koker Hosch and Hunk Lomus were classed as mere outside workers. One had

Nevertheless, rumor mongers of the underworld could foresee a shift in tactics on the part of the unknown big

shot. The Shadow had entered the game with a vengeance. No supercrook, no matter how confident, could

afford to disregard the menace of the cloaked fighter who could bob up from nowhere.

Among the gathering places in the bad lands, "Red Mike's" formed a most notorious hangout. Red Mike's

was located close to the Hudson River, in the district known as "Hell's Kitchen." The dive was on a second

floor, above a dirty restaurant; it was named after the proprietor, a rowdy called "Red Mike."

The police had their eye on Red Mike's; thus no recognized underworld members hung out there.

On this particular night, the dive was filled with small fry only. Red Mike, himself, was on the job, keeping

an eye upon all who entered. If stoolies were present, they were welcome. Rumors and unlikely ones

Off from the main part of the dive was a smaller room that formed a passage to the side exit. This room was

reserved for the select few whom Red Mike trusted. A solitary rowdy was in the room tonight. He was

crouched at a table, nursing a bottle of grog and keeping wary watch toward the halfopened door that led

NO rumors had involved Chip. He had chosen the side room on the pretext that there were too many bums in

the main joint. Red Mike had accepted the explanation. Chip, nervous at first, had become quite at home in

the little room. He could hear the buzz from beyond the door. Pushing aside a bottle and glass, he arose from

Just as he reached the threshold, Chip heard a sound behind him. He wheeled about. His face showed

startlement; then regained its half grin. Chip recognized the tall, stoopshouldered arrival who had entered

"H'lo, Beak!" expressed Chip. "Squat an' help yourself to a slug outta the bottle!"

The arrival nodded. He sat down, poured himself a drink and raised the glass. He stopped to look at Chip;

"The drink can wait," decided Beak, gruffly. "There's something I want to talk about, Chip. That's why I

Chip eyed Beak warily. The pair had been pals long ago; they had remained friends when they split. Chip

Like Chip, Beak had an appropriate nickname. His face, otherwise flat, was distinguished by an overlarge

nose. His eyes were deepset; he kept them half closed as he looked toward Chip. The latter remembered that

Chip's query was hoarse. Beak gestured with his right hand, up and down, to quiet his old pal's nerves.

"Just something that was spilled to me," he informed. "By a bimbo that we both used to know."

"Say, Beak," he remarked, "I t'ought you was laid up. Heard you was crippled in that fight with the bulls,

"I was," interposed Beak, harshly, "I was flat on my back in my room at the Hotel Spartan when this bird

Chip's pursed lips twitched at mention of the dead mob leader. Beak gave a hoarse guffaw; then leaned

"Don't let it give you the jitters," he confided. "I ain't been piping what Hunk told me. Keep your shirt on,

"What Hunk said was this," resumed Beak. "He was going out on a coverup job; but he wouldn't tell me

who for. I didn't want to ask him, anyway, because I knowed it was confidential. Hunk figured there was

"That's why he wanted me to be ready. The last thing he says all of a sudden like was that if I heard from

you, it would be O.K. Said you was working with the same guy that he was. Then Hunk goes and gets

Beak guffawed sourly, in remembrance of Hunk. Chip watched his old pal finger the glass. Beak became

silent, as if expecting Chip to speak. Chip's nervousness returned during the pause. Suddenly, he began to

"YOU'RE a pal, Beak," piped Chip. "That's why I can talk to you, seein' as how Hunk told you some of it. I

ain't had nobody to talk to, since last night. It's made me jittery, Hunk being croaked!"

"It's screwy!" continued Chip. "The whole thing right from the beginning. Hunk didn't know the real lay; he

was just on the outside. There ain't many guys that would believe this goofy business, Beak. That's why it's

Beak nodded again, as Chip paused. Chip licked his lips, picked up the glass that Beak had discarded. He

"It began with Pinky Garson," he whispered. "You know Pinky. Him an' me was pals. Pinky's took it on the

lam; he's got his outta the racket. So it don't matter if I mention him. Anyway, first Pinky comes to me. Says

"I don't know. I went with Pinky; but it was night an' he drove all over the map. Anyway, we come into the

cellar of some house, outside of New York, an' Pinky takes me upstairs. We go into a room; an' that's where I

"Whatta ya mean?" queried Beak. "Is that some fancy moniker they tacked on a guy? Calling him The Head

"It wasn't no guy we saw. It was a head, Beak! A livin' head, sittin' in a square box, with the front open! On

Beak's eyes turned toward the halfemptied bottle. He was gauging how much Chip had drunk.

"I ain't been hittin' the bottle, Beak," protested Chip. "I ain't had the rams. I ain't cracked, neither. Listen;

Pinky Garson was takin' on a job an' The Head had told him what to do. He needed a guy to help him."

"That's what it did," he expressed in an awed tone. "It tells Pinky all about a bird named Herbert Threed, that

was to have some stocks passed to him, in an office. Pinky brings me back to New York. We go to the

"I run the elevator, while Pinky passes himself as Threed. We gets the swag an' beats it. Pinky was headin'

out of New York anyway. So he kept on goin'. Tells me I'll hear from The Head through somebody else."

Chip nodded. He was feeling steadier through this chat with an old pal. He explained further.

"SQUINT had Koker Hosch there," said Chip. "To cover up, see? Because Squint was goin' to send Koker

along to see The Head. But Koker gets in a jam; he takes it on the lam. So Squint had to pick another guy."

"Moose Sudling. An' Moose uses me, like Pinky an' Squint had done. Moose an' me stages the job last night

"Yeah. The same as Squint had Koker. Hunk was supposed to be the next in line. But he got bumped. There

"Moose is out. He's on the lam because he croaked that caretaker at Rydler's. It goes back to Squint. He's still

in town. Where, I don't know. But, listen, Beak. Any job that The Head stages is a pip. It's his brain runs it,

"Or Moose. Sure. But they don't have to use the bean. The Head gives 'em all the dope. They put it down on

paper. Where to be an' when. What to do. It runs like a clock! Every job is a setup "

Beak Thungle was looking past Chip Mulley, toward the halfopened door to the main dive. Beak could see

men seated at tables beyond the doorway. Buzzing chatter and raucous guffaws were coming from the

"Listen, Chip," said Beak, in a low tone, "This ain't no spot to do too much talking. This is great stuff you've

"I'm going out by the side way. You stay here. Finish a couple of drinks; then go out through the main room.

I'll be in there, but don't say nothing to me. Maybe a hello, if I holler to you but go on out, right after. Head

Chip nodded. Beak arose and strolled out by the side door. Chip gulped the remainder of his drink. He made

another reach for the bottle. Just then, the door from the main room swung wide. A tall, stoopshouldered

Chip Mulley gazed, rigid. The man who had entered from the main room was the very one who had left, only

"Whassa matter, Chip?" Beak plopped at the table. Chip saw that he had been drinking heavily. "Say you

Beak guffawed as if his remark had been an apt jest. He reached for Chip's bottle, raised it and took a long

"Thassa good one!" croaked Beak. "Chip Mulley been talking to The Shadow! Thass another good one for

Chip heard no more. He had risen; he was stumbling toward the door to the main room. He reached his

objective; quivering, he faltered to a table, amid groups of riotous hoodlums. Terror had seized the

chipmunkfaced crook. He had encountered two Beak Thungles: one false, the other actual.

He knew why the first had gone so suddenly, with suggestion for a later conference. The first Beak had been

looking out into the main room. He had seen the second Beak enter. The first Beak Thungle was the

But the second Beak Thungle had unwittingly supplied the answer. His drunken jest had hit the truth. His

face distorted with fear, Chip Mulley realized the true identity of the person who had played Beak's role.

The underworld was not the only portion of New York that buzzed with news of crime. At the very hour

when Chip Mulley had guessed his own mistake, persons elsewhere were discussing the robbery of last night.

One was Hal Rydler. His companion was a woman a few years older than himself, although her artful

makeup gave her a younger appearance. The woman was Adele Rayhew; until a few months ago, she had

been engaged to Hal's brother Percy. This evening, Hal had called Adele and invited her to dinner.

They were finishing their meal, in the roof garden of a swanky New York hotel. Their corner table was a

secluded one; nearby diners had departed. Adele decided that she could speak in confidence to Hal.

"Nice of you to take me to dinner, Hal," remarked the girl. "I was afraid you would be prejudiced because I

broke my engagement to your brother. Percy was very much upset about it. But, really, Hal, it could not be

Hal made no comment. He had a reason for his silence; and his meeting with Adele Rayhew was part of it.

"I could help Percy," the girl was saying. "Really, Hal, I could. But I'm sailing for Europe day after

"Wait a moment." Hal had found the opportunity he wanted. "You say that you could help Percy. I suppose

"I know why you say that," continued Hal. "About six months ago, some jewels of your own were stolen.

"As I recall it," persisted Hal, "you hired a private detective. He visited a servant who had once been in your

Adele made no reply. Her silence indicated, however, that Hal's account was a correct one.

"That was an inside job," remarked Hal. "This robbery was not. Why do you still think that Percy's diamonds

Adele started to speak; then bit her lips. She looked across the table and saw a steady expression in Hal's

"It it was a very odd circumstance," she said "the one that enabled me to recover my gems. Months ago, I

heard of something spooky something so ridiculous that I laughed at it. I couldn't bring myself to believe in

spirits. But when I heard that this was something scientific, I went to it. A friend took me there."

"An old professor owns the Oracle, Hal. His name is Professor Caglio. He lives near the town of Littenden, in

"Littenden," mused Hal. "I know where it is. Only twenty miles from Newark. Yet it is wild country

"PROFESSOR CAGLIO has a house with no windows," explained Adele. "In it is a weird room, with many

strange mechanical figures. One of them is the Oracle. It is a head that talks."

"It seems to be alive. But the professor says it is purely a mechanical creation, endowed with human wisdom.

He calls The Head by an odd name that begins with Z. I think I can remember it yes, the name of The Head

"What does The Head do?" he queried. "Sing songs and tell fortunes? You can't cross its palm with silver.

"I asked questions of the Oracle. It answered them, very wisely. The Oracle told me where my stolen jewels

could be found. My gems were worth almost four thousand dollars, Hal. The detective that I hired did just as

I told him. He went to Logan's home Logan was the servant whom I had discharged and threatened him

"And how much did you have to pay Zovex? Or the owner of the Oracle, Professor Caglio?"

"Not a cent. Professor Caglio does not need money, Hal. He is a scientist. He has invented a great many

"Including the talking head." Hal chuckled. "Well, Adele, the next step is to visit Professor Caglio and see

what Zovex has to say about Percy's diamonds. Maybe The Head will make another lucky stab."

"It is not luck, Hal. Really, the Oracle is uncanny! But I am afraid that it will speak no longer."

"I was the last person to consult it. All the others my friends had left New York. The Oracle advised all of

them. It told me that my trip to Europe would be wise. In fact, I should have left two weeks ago, according to

"I see. If you went out to Caglio's tomorrow, he might not like it? That is, The Head might be angry?"

"Zovex gives no new advice to those who do not follow the old," she said, as though repeating words that

The Head itself had once uttered. "So I can not very well visit the Oracle until after I return from Europe."

"I believe so. I was taken there by friends. I suppose I would have the privilege of recommending another

"That settles it. When we go down to the hotel lobby, Adele, you can write a letter of introduction. One that I

"Why should he? I shall tell him that I live in Baltimore, and that this was my first trip to New York since I

received the letter. Moreover, I shall explain that it is the first time that I have needed advice from Zovex."

ONE hour later, Hal Rydler arrived at his hotel, after taking Adele Rayhew to her apartment. In his pocket, he

carried a note that the girl had written. That note would serve as his passport to visit Professor Caglio. It was

Incredible though the girl's story had been, Hal had been impressed. He had remembered the mystery of the

gems which Adele had recovered. This was the first time that he had ever heard the explanation. Adele had

added some further details regarding Professor Caglio's strange abode. Her statements had whetted his

It would be a longshot gamble, perhaps; but the visit seemed worthwhile. It appealed to Hal's love of

adventure; and this curious talk of an Oracle seemed to fit with strange circumstances that Hal had already

experienced. He had not forgotten that heavy, clumping prowler whom he had observed at the scene of the

NOT long after Hal Rydler had strolled to his hotel, another man began a journey along a New York street.

This was Chip Mulley, departing from Red Mike's. The crouchy crook had lingered long at the dive. He had

made one trip into the side room, in an effort to talk with Beak Thungle. He had found his old pal in a

Every corner made Chip shudder. Furtively, the scared crook kept staring at spots of blackness, expecting one

to come to life. He had talked with The Shadow! He could picture that dread avenger no longer posing as

Past one corner, Chip faltered. He saw thick gloom that looked almost like a living shape. Hurriedly, he

staggered onward and dived from view beyond a corner. A moment later, the blackness moved. Chip's fear

Chip's affrighted gait had been a giveaway. The Shadow knew that the furtive crook had seen the real Beak

Thungle too soon. The Shadow had a remedy. He moved to a spot where a cab was parked. He whispered

instructions from the darkness beside the taxi. The cab rolled away. It took the corner that Chip had turned.

The cab passed the hurrying crook and turned another corner. There, a man dropped out. As Chip neared a

corner, the man came into view. Chip saw him and stopped. Sight of a square, wellchiseled face gave him a

The squarejawed man heard Chip's greeting. He recognized the nervous crook. That was not surprising.

"Hello, Chip!" returned Cliff. "Where are you heading? Over toward the Black Ship?"

"Yeah." Chip stopped suddenly. "No I'm only goin' part way there, Cliff. Say if you're goin' along "

"What's the matter, Chip? You look jittery. Guess you're like a lot of others I've run into tonight. Been

"He's one mug I'd like to meet!" continued Cliff harshly. "The Shadow! I'm gunning for that phony!"

Chip's eyes widened. He remembered that Cliff Marsland had formerly bragged of being on The Shadow's

trail. Others had boasted of such a mission; they had not long survived. When Chip came to consider it, he

"You think I'm kidding?" queried Cliff, as he looked at the shuffler beside him. "If you do, take another think.

It isn't healthy to kid about The Shadow. Plenty of wise guys have found that out when they stopped bullets

"But I've got the Indian sign on The Shadow. I clipped him a couple of times, in a fight. I'm one bimbo that

he doesn't like to tackle. I'm ready to take a shot at him any time! But how can anybody find him? I'm likely

"I've tried to find guys that The Shadow is after. I've found them yes but The Shadow has always met up

with them ahead of me. They've been lying cold, full of lead when I've come across them. The trouble is,

most guys are afraid to talk when they think The Shadow is tailing them. I don't blame them; but if they'd talk

They had reached a street that led to the Black Ship. Cliff turned to head in that direction. Chip clutched him

"Stick with me, Cliff!" he pleaded, hoarsely. "I got somethin' to spill to you about The Shadow!"

"I can't pipe it here, Cliff. Listen; I've got a hideout down the line. Let's slide in there."

They followed a side street and reached an alley. Chip darted a worried glance behind him; then took to the

alley, with Cliff beside him. Chip unlocked the battered door of a dingyfronted building. He and Cliff

A soft laugh whispered from darkness near the corner. A cloaked form moved away. The Shadow had

followed. He had seen results. His role of Beak Thungle was through. He had deputed Cliff Marsland to keep

Through that move, The Shadow could hope to find a trail. Soon, perhaps, he would reach that mysterious

adversary whom Chip had termed "The Head." The Shadow was seeking to solve the riddle of the master

In his present course, however, The Shadow had dropped Hal Rydler as a factor. He believed that the rescued

man was by this time far from danger. The Shadow had missed a possibility. He did not know that Hal had

"Nine o'clock," growled Cliff, suddenly. "What's the idea? You tell me you're gonna hear from Squint

"It ain't no stall, Cliff," protested Chip, with a whine. "Honest it ain't! I'm due to hear from Squint any time.

That's what I got the phone here for." Cliff eyed the telephone, resting on a soap box in a corner. It looked out

Cliff was anxious for Squint's phone call for another reason other than Chip's. Chip wanted to tell Squint of

the masquerade of The Shadow as Beak Thungle. Cliff wanted to make contact with Squint and get a line on

The Head's hideout. He had talked Chip into putting in a good word for him with Squint; and hoped to get in

Using the pretext of getting cigarettes, Cliff had slipped out of the room a few times in the twentyfour hours

"Hello..." Chip had raised the receiver. "Hello, Squint. This is Chip... Yeah. Been here since last night. Cliff

"Hello, Squint! This is Cliff Marsland... I pulled Chip out of a jam last night. Chip met the Shadow. He

thought The Shadow was Beak Thungle. Chip talked too much. Told him about The Head."

"Now I got an idea, Squint. I'm one guy that can handle The Shadow. But I can't find him. Chip says The

Head knows everything. Maybe he'll have a way to spot him. Chip says you'll fix it for me to meet The Head.

There was a pause. Squint knew Cliff's reputation as a guy who wanted to get The Shadow and wasn't afraid.

"It sounds jake, Cliff," was the word. "I'm in Jersey City now. You beat it right away and meet me at Duke's

Cliff hung up the receiver, told Chip what Squint had said. The Shadow's agent picked up his hat, waved a

A few moments after Cliff's departure, the barrier to the room opened. There was a figure on the threshold.

Flickering gaslight revealed a cloaked form. The glow of the jet was reflected by burning eyes that stared

Through Chip's bewildered brain ran sudden thought, suspicion. Marsland must be working with The

Shadow! The Shadow's entry immediately following Marsland's departure, plus Cliff's desire to meet up with

Quivering, Chip backed toward a corner, gaze hard on an automatic that had slipped from under The

Shadow's cloak. Chip's eyes showed a plea for mercy that would have befitted a trapped rat.

A sinister laugh came mirthless. Echoes repeated The Shadow's whispered mockery. Backing to the door, the

cloaked visitant thrust his automatic beneath his blackened garb. Like a living shroud, he blended with the

A SUDDEN gleam showed on Chip's face. He was free. He had learned facts. Cliff Marsland was working

Not in New York; but elsewhere. By contacting the right crooks, Chip could start a man hunt for The

Shadow. Cliff Marsland would be the one through whom The Shadow could be traced. Shakily, but with

nerve returning, Chip began to pack his few belongings. He stopped suddenly as he heard footsteps at the

Chip snarled as he wheeled about. His hand halted on the way to the pocket of his tattered jacket. Two men

were at the doorway. Both were holding leveled guns. Coat lapels went back. Chip saw the gleam of badges.

Chip raised his hands as he gasped the recognition. The Federal agents stepped across the threshold. One tall

"Come along. We're taking you West. That's where they want you in St. Louis. Frisk him, Terry. Then

Ten minutes later, Chip Mulley was riding in a taxi, sulkily seated between the Federal men. He had reason to

be morose. Chip knew that St. Louis would be but the stopping point on the way to a Federal penitentiary.

Another thought rankled him, also. His opportunity to make trouble for The Shadow was finished. Chip

would have no chance to pass his news to bigshots. And from these conclusions Chip Mulley gained

Chip knew who had dispatched the tipoff to the Gmen, that they might trap him in his hideout. The word

had come from one who seemingly knew everything including the fact that Chip had been wanted for his

While Chip Mulley was taking a ride that made him picture prison walls, another man was finishing a

journey in New Jersey. Singularly, this chap was viewing a building that looked very much like a prison. Hal

It was a moonlight night. Hal had borrowed a coupe that belonged to his brother Percy a car that was

always at his disposal. Thanks to the brightness of the night, he had easily found the road to Littenden. He

had located Caglio's residence; and again the moonlight was serving him. He could see the house quite

Adele Rayhew had described the house as a strange one. Hal saw good reason for the definition. Seen from

the driveway which Hal had entered, the house appeared as a twostory structure, built of wide stone walls

that formed a perfect square. It loomed like a vast gray mausoleum, and the formation of the walls held Hal

Hal had come from a side road, following a driveway that curved through a wood. Thus he had gained a

changing view of Caglio's house. He had seen both sides, as well as the front. Convinced that none of these

three walls held an entrance, he decided that the back must be the only mode of access.

A driveway continued around the house. As Hal followed this route, he looked upward, to note that the flat

roof was topped by a parapet that followed all along. The drive sloped downward as it neared the back of the

house. Taking the final turn, Hal came to the rear and viewed the fourth wall. Like the others, it was blank

The slope, however, had produced a space that showed a portion of the cellar wall. This was of concrete, an

extension of the building's foundation. The drive turned sharply toward the house. As he reached the

terminus, Hal saw a sliding door, large enough for a car to enter. The door was set in the foundation. It was

Some one must have observed the coupe's arrival, for the sliding door opened sidewise. Hal saw the interior

of a large garage. He drove boldly through the doorway and brought his car to a stop upon a lighted space

that was set with stone posts. He peered from the window in time to see the sliding door close behind him.

There was only one other car in the basement garage. It was a long, powerful roadster that stood in a corner.

A man stepped from behind a pillar and approached the coupe. Hal noted that he was slender, but of wiry

appearance. The man was pokerfaced. His eyes peered sharply from beneath the visor of a chauffeur's cap.

The demand was rasped. Apparently, the man had expected some other visitor and was puzzled when he

"I want to talk to Professor Caglio," replied Hal, quietly. "I am a friend of Miss Rayhew. I have a letter of

The chauffeur went to the inner wall and picked up a telephone. Hal watched him as he held brief

conversation. The chauffeur turned and beckoned. Hal stepped from the coupe and advanced.

"I'll take care of your car," the chauffeur told him. "The prof says that you can come upstairs."

HE opened a door and showed an automatic elevator. Hal entered. The chauffeur followed. They rode up to

the main floor and stepped out into a hallway. Hal noted a mellow, indirect light a contrast to the glare of

They were at the very front of the house. The elevator had brought them up to the spot where a front entry

should have been. The hall was long and wide. It ran the full depth of the building. On the right, Hal saw an

opened door that led into a large, comfortably furnished living room, with a huge fireplace. At the left he saw

The walls of the living room were solid. It had no windows; nor did it have a connecting door to any other

room. The fireplace was at the front; at the back of the room was a large, broad mirror, set in a huge gilt

The dining room was likewise windowless; but it had a door in the back wall. One that obviously led into a

Hal had time for these observations while the chauffeur was closing the door of the elevator. Then the man

Just past the living room, Hal made new observations. There were two more doors upon the right, both to

smaller rooms. There was one on the left; probably a way into the kitchen. The hallway turned left when it

reached the back of the house. Hal decided that it must lead to a stairway at the rear of the kitchen.

But he had no opportunity to learn further details. The chauffeur had stopped at the middle door on the right.

The portal opened. Hal stared into a small study. Then he eyed the man who had opened the door. He knew

Hal saw a tall, gawky figure, with long, disjointed arms that hung from bent shoulders. He eyed a withered,

tightskinned face, smallfeatured and with eyes that peered like sharp beads of light. Above, a crop of wild,

"Good evening!" Caglio's voice was a cackle. "I give you welcome! May I ask your name, my friend?"

Caglio was jabbing a withered hand toward Hal. The visitor clasped the professor's claw. The chauffeur had

Hal saw the professor give a sudden start. Then lips croaked a pleased chuckle. Hal had already classed the

professor as eccentric. He saw no significance in the whitehaired man's odd action.

The chauffeur went toward the front of the house. Professor Caglio closed the door. He motioned Hal to a

chair beside a large desk. Hal handed him Adele's note. Caglio seated himself and began to read the message.

This allowed Hal time to look about him. The study was a small room; but it resembled the others that Hal

had seen. Like the hall, all had one dominant feature of decoration: The walls were of paneled oak. One wide

panel; then a narrow one. The same order was repeated. The panels went half way up the wall; above was a

The light was pleasant throughout the study. The air, too, was fresh, which surprised Hal, since the house was

windowless. He noted that the professor used a desk lamp in order to read the letter. That was natural, since

He led the way from the study. They went toward the rear of the house and stopped at the last door on the

right. The professor turned the knob. They entered another lighted room, paneled like the study, and of

HAL blinked in utter amazement, when he saw the contents of the room. Professor Caglio indulged in a

The room was like a miniature museum; every exhibit was an oddity. To his left, Hal saw a waxwork figure

that was seated upon a large, oblong chest. The figure was almost lifesize. It was attired like a Turk. In front

To Hal's right was a smaller figure that looked like an oversize doll. It was seated upon a fourlegged bench.

Its dress was adorned with ruffles. The figure's lap supported a small writing board, to which its left hand was

clamped. Its right hand held a pen, and the head was tilted forward so that its lifeless eyes looked straight

Cages were hanging from the ceiling. These contained imitation birds of varied plumage. Near the far end of

the room was a squaretopped mahogany table, supported by a blocky pedestal that served as a leg. Beyond

the table, Hal saw a small safe in the wall; above it, a shelf with a row of cubical boxes.

Some of the boxes had open fronts. Inside them, Hall saw waxwork heads. Two had the faces of women; a

third held the visage of a wisefaced Hindu. Hal wondered if this could be Zovex.

"One moment, Mr. Rydler!" Professor Caglio cackled the exclamation. "Before we proceed with the

consultation, let me explain the purpose of this room. It is my laboratory; where I experiment with various

"Yes." He pointed to the dolllike figure at the right. "Here we have a replica of the JacquetDroz

He opened the back of the doll. Hal saw that the figure was filled with clockwork. The professor adjusted

several levers, wound the clockwork and set it in motion. A slight ticking sounded, even after he had closed

There was a pad of paper on the square table at the back of the room. Caglio tore away a sheet and brought it

to the doll. He placed the paper beneath the figure's right hand. He opened the top of a small inkwell that was

The figure's tiny hand began to move. It advanced, jerkily dipped the pen into the inkstand. The hand

quivered with an eccentric motion, shaking off drops of ink that spattered into the inkstand. Approaching the

paper, the hand began to write, forming quaint letters in slow, painful fashion.

Hal blinked. The figure was inscribing his own name: "Rydler." With the finish of the sixth letter, the hand

raised. With a slight click, the doll's face looked upward, like that of a child, expecting approval.

PROFESSOR CAGLIO smiled. He turned to the chess player and opened a door that was cut in the cloth

front of the figure's chest. He showed a mass of mechanism. Closing the door, Caglio opened another that

was set in the right side of the oblong box. He revealed another display of clockwork.

Closing that door, he opened the left side of the oblong box and pointed to another collection of machinery.

"Seat yourself," said Caglio to Hal. "Test your skill against that of the Turk. I presume that you play chess?"

Hal nodded. He took the chair opposite the chess player. Hal had the white pieces. He began with the Ruy

Lopez opening. He made one move. The automaton swung its right hand forward. Its fingers plucked up a

The game progressed swiftly; for Hal was more interested in seeing the figure operate than he was in the

game itself. When the chess player captured pieces, it dropped them beside the board. Suddenly, Professor

"Incredible!" he remarked. "How can a mechanical device be arranged to counter all the possible moves of a

"You saw the intricate machinery, explained the professor. "Thousands of tiny levers are necessary. That is

why the large chest is needed to house the elaborate mechanism. Von Kempelen invented this automaton. It is

Caglio looked toward the bird cages, with their mechanical occupants. He decided to pass them for the

present. He motioned Hal toward the back of the room. He pointed to the row of cubical boxes.

"A name given to heads that speak," returned Caglio. His tone was hushed. "These are mechanical, yes. But

"No," replied Caglio. "That is Ganara. A head that displays no more than mechanical attributes. This box"

he picked a closed cube from the shelf "is the one that contains the head of Zovex."

Carrying the box in careful fashion, Caglio started to the center of the room. Hal moved along with him. The

professor stopped suddenly beside the squaretopped table. He pushed a stack of books away; then held the

box by a handle at the top. The box was swaying in his right hand, a foot above the table. Eagerly, Caglio

"Observe!" he cackled. "See! For the first time! The face of Zovex The Head that will live forever! Zovex,

The front of the box swung downward on a hinge. Hal Rydler saw the head within the box. He spied a face of

waxwork, that gleamed in the reflected light. Spontaneously, a startled, instinctive cry gulped from Hal's

The head within the box had livid lips. Its nose was wide. Its eyes were rounded orbs that bulged from

beneath thick brows. Its waxen forehead was a mass of Vshaped wrinkles. Its hair was black and shaggy.

The face of Zovex was identical with the visage of that fearful, bulky prowler whom Hal had seen within his

Professor Caglio placed the box in the center of the table. He turned to eye Hal Rydler sharply. The visitor's

"What troubles you?" queried Caglio, cackle harsh. "Others have not quailed at sight of Zovex."

"Nothing," replied Hal, abruptly. "It Zovex well, the face reminded me some one "

"No, no! It was just a fleeting thought that gripped me. I found it hard to realize that the head is not alive."

Professor Caglio laughed in cackly fashion. His eyes took on their wildish stare.

"There are those," he chortled, "who believe that Zovex lives. Some who are wise believe it. Perhaps they are

"I disagree. Remember, I am a scientist. Yet I have learned of phenomena which science cannot explain.

From antiquity, there have been reports of Oracles. Some of them the wisest were speaking heads. Like

Caglio pointed a bony finger toward the evil face of Zovex. Hal, staring, found sight of the head more

"The head of Mirme was an Oracle," affirmed Caglio. "It was brought from Asia, into Scandinavia. The

Oracle at Lesbos was a speaking head. It was the head of Orpheus; and it predicted the death of Cyrus, the

"There was the head of the physician Dalban, that lived long after death. A legend, perhaps, of the Arabian

Nights; but such stories often hold foundation, particularly when later discoveries support their possibility."

Professor Caglio paused. His cackle had become shrill. Hal wondered if this could be the old man's mania.

"The ancients called such heads 'androides'," resumed Caglio, wisely. His tone had suddenly calmed. "The art

of constructing speaking heads came down through the Middle Ages. Just prior to the French Revolution,

Mical presented a collection of speaking heads to the French Academy of Sciences.

"Mechanical devices, yes. But there lies a difference between the androides and the theraphim. The androides

are constructed. The theraphim are the embalmed heads of the dead. This head the head of Zovex is of

Hal paused. He watched The Head. Professor Caglio was close beside the table. The old man's claws were

The lips of Zovex moved. Their motion was mechanical. A voice grated from the lips:

Hal stood silent as the lips ceased moving. Caglio leaned forward and put a question of his own:

Eyelids dropped like shutters. The glare was gone from the waxen face. Hal turned toward the professor.

"Zovex sleeps!" whispered the old man. "Come! We must be gone until the head awakens. Then the Oracle

will answer. Within that head" Caglio's forefinger was wagging "lies a living brain!"

They went from the strange room. Hal, in the hallway, caught a last sight of the waxwork head in its box

upon the table. Then Caglio shut the door. With a slight smile, the professor conducted Hal forward to the

"We shall wait here," declared the professor. "The Oracle must be given time to decide upon an answer."

"Zovex needs no details," responded Caglio. "His brain will picture every circumstance."

THEY sat down in comfortable chairs before the fireplace. Hal heard the crackle of logs. A fire was burning;

as he looked about, he could see the reflection of the blaze in the wide giltedged mirror on the opposite wall

of the room. He turned toward the fireplace and watched the sparkle of the logs.

"An idea of mine," chuckled Professor Caglio. "This house is windowless. I keep it entirely airconditioned.

The temperature varies in different rooms. An open fire is cheerful; so the living room is kept cooler than

The door opened as Caglio was speaking. Hal looked about; then arose as a girl stepped into the room. She

"This is my niece," he told the visitor. Then, to the girl: "Martha, meet Mr. Rydler. Remain here, Martha,

The girl took a chair. Hal sat down as Caglio departed. As soon as the old man was gone, the girl spoke to

"My name is not Caglio," smiled the girl. "I am Martha Keswick. Caglio is my uncle's name; but not his real

"No. I do not know his actual name. Perhaps I should not tell you this, Mr. Rydler; but I am worried about my

uncle and his eccentric notions. I promised myself that I would tell the truth to the next visitor who came

here. That is, the next one like yourself. There have been others here, others whom I could not trust!"

The girl stopped abruptly. Caglio had returned, bringing a tall cadaverous man with him. He introduced his

"This is Mr. Selfridge," stated Professor Caglio. "He is my technician. He attends to the detail work of the

The cadaverous man bowed when he heard the compliment. He remained in the room while Professor Caglio

went out again. Selfridge made no effort to begin a conversation; nor did Martha Keswick resume the

Hal, silent, gained a sudden suspicion. Caglio had deliberately introduced Selfridge in order to keep his

visitor under observation. This meant that the professor might have suspected something because of Hal's

While Hal was pondering on the subject, Caglio reappeared. He bowed from the doorway and invited Hal to

accompany him. When he arose, Hal caught a warning gaze from Martha, who was seated near the fire. He

smiled and gave a slight nod; then joined Caglio. The professor led him directly to the rear room on the right.

"Sufficient time has elapsed," remarked Caglio, in his crackly tone. "I believe that the Oracle will speak."

THE cubical box was on the table, where Caglio had left it. The head was staring from within. The bulging

Glaring eyes remained fixed. Lips alone moved. The speaking head rasped its answer.

"All can be seen by the eyes of Zovex," it announced. "I have viewed the place where the diamonds lie. They

Hal gaped. His first observation had given him two theories regarding the Oracle. One, that Professor Caglio

was a ventriloquist. That idea was shattered. Hal was standing closer to The Head than was Caglio. The

professor could not have simulated the voice. Not on this occasion, at least. Ventriloquism was impossible,

Hal's second theory was that of a mechanical head. The previous statements had sounded like set remarks.

The present utterance was too prolonged, too sustained to be that of a mere machine. Hal tried another

Hal was convinced that The Head lived. Professor Caglio was plucking at the visitor's sleeve. Persistently, the

"Zovex has spoken," grated The Head. Eyes glared; their gleam lifelike. "When fools hear words of wisdom,

"Come!" cautioned the professor. "Do not offend the Oracle! Zovex will speak again tomorrow. Come! We

Hal followed the professor from the room. Hal's head was in a whirl. His second theory was flattened. His

chance questions, particularly the last, were ones that could not have been accurately anticipated. No

phonographic records could have accounted for those sharp responses. The Head was alive!

WHEN they reached the study, Hal slumped in a chair. He was totally bewildered. He was positive that he

had viewed the same head that he had seen upon the clumpy man in New York. Yet this head had rested in a

box upon a table; and the pedestal leg of the table was less than two feet square.

Professor Caglio must have noted his guest's bewilderment. He clamped a friendly hand upon Hal's

"Wait here," he remarked. "I shall bring the models of some new inventions that will interest you. We shall

"No!" Hal was on his feet before Caglio reached the door. "I must go into New York. Positively! I can come

"Very well." Caglio had opened the door. His sharp eyes saw the determination on Hal's face. "Nevertheless,

He stepped out into the hall and closed the door. Hal went back to the desk. He sat down and stared at the

He could not locate the direction from which the noise came. He walked about the room; then nervously

approached the door. He tried the knob. It did not budge. Hal realized that he was locked in the study.

Clutching his hands, he looked toward the panels. They were all alike, and the walls were thick. Hal had

guessed that last fact from the sizes of the rooms. Every apartment, the living room included, seemed smaller

Hal started toward the door again. On the way, he faltered. He was becoming dizzy. The hissing was a terror

to his ears. He clutched the doorknob. His hand slipped from it. His head began to swim. He sagged to the

Half crawling, Hal dragged himself to a chair and rolled into it. He tilted his head backward and panted as he

stared toward the ceiling. The hissing ended. Hal heard the click of the doorknob; but he was too weak to

THE old man's eyes expressed pretended surprise. Caglio called to some one outside the door. Selfridge

"Bring Marley," ordered the professor. "Mr. Rydler is not feeling well. We must help him to his room."

Selfridge returned with a smugfaced man who looked like a servant. Hal had lost his dizziness; but he was

too weak either to aid or resist when Selfridge and Marley dragged him to his feet. Professor Caglio stood

nodding while the pair helped Hal from the room. They moved along the hall to the back; there they turned

He managed one last look toward the front of the hall. Professor Caglio was standing by the open doorway of

the study. Martha had come from the living room and was speaking to her uncle. Hal could see anxiety on the

Marley supporting him. He did not care where they were taking him. He was feeling strange aftereffects of

Selfridge and Marley had dragged him into a little room, Hal Rydler had become an inert burden. His body

The door clicked when the pair departed. Hal lay in solitary quarters, beneath a ceiling of frosted skylight

The moon was shining from directly overhead at the time the glow had first shown Hal Rydler sprawled upon

his cot. It had advanced but little farther when its mellow light revealed another sight, outside of the

A second automobile was coming to the graywalled house. This car was a sedan. Its driver knew the route,

for he followed the curving driveway without hesitation. Yet his course, though steady, was slow. The driver

Leaning half around, Cliff dazed steadily back along the drive. He saw nothing; yet he knew that there was

reason for Squint's conjecture. A car had actually been on the sedan's trail. Cliff had spied it at odd intervals.

"Guess we're O.K.," decided Squint, as they took the final turn. "Lamp the house, Cliff. Screwy joint, ain't

"How do you get in the place?" queried Cliff. "Seems like there's no door to it."

They had reached the entrance to the garage. The sliding door was on the move. Squint Proddock drove the

car into the space beneath the house. The door slid shut; Havelock came over to meet the visitors.

The chauffeur recognized Squint. He asked no questions concerning the crook's companion. He simply led

the way to the automatic elevator and conducted the arrivals to the main floor. He took them to Caglio's

"Hello, prof," greeted Squint, meeting Caglio inside the room. "Meet Cliff Marsland. A pal of mine. Come to

"Maybe. Maybe not. Wait until we've talked to The Head. Cliff has some dope to spill."

"I know that. I'll start the speech with Cliff here adding the details. There's been trouble, prof."

A STRAINED expression showed upon Caglio's face. Without another word, the whitehaired man led the

way to the room at the back of the hall. The trio entered. Cliff stared, while Squint grinned.

"Looks goofy, don't it?" queried the crook. "Wait'll you see things working, Cliff. You'll think different. Say

"Yes." Caglio nodded. "There was a visitor earlier this evening. One whom I did not expect. His name was

"Rydler?" Squint spun about. "Say that's the guy who owned the fancy ice! The diamonds that Moose

"This was not Percy Rydler," cackled Caglio, interrupting, "It was his brother, Hal. Mere chance brought him

There was a significant croak to Caglio's final statement. Squint grinned again; then became serious.

"Lamp this," remarked Squint, in an undertone to Cliff. "And keep your ears open, bozo."

He approached the table and faced the open front of the cubical box. Cliff looked past Squint to view the ugly

face of Zovex. He was gripped by an immediate dislike for that glaring visage. But Cliff was too experienced

"Bad news, Zovex," informed Squint. "I guess you know about Moose croaking that guy Jemley; and having

Hunk Lomus around, like I had Koker Hosch. That was tough enough; but this is worse.

worry about The Shadow. Cliff stuck in the hideout, along with Chip, and joined up with me tonight. Chip

SQUINT paused, as though expecting a reply. The Head remained motionless. Professor Caglio approached

"Not much for me to say." Cliff looked straight toward The Head. "I'm out to get The Shadow. I'll bump him

any time I get the chance. What I want to know is, how can I get at him? Squint says you can tell me."

Cliff waited. The head retained its waxfaced impression. Cliff was beginning to consider the game a hoax,

An interval; then eyelids dropped. Caglio turned to Cliff and Squint. He added his own statement:

Squint nodded. He turned to Cliff. "That just means The Head will think it over," stated Squint. "He don't

always hand out info in a hurry. There's a brain inside that bean. This is a scientific racket, Cliff."

Cliff was nodding. Caglio noted his pokerfaced expression. The old professor went to the table.

Deliberately, he tilted back the top of the cubical box and lifted the head from its resting place.

"I shall show you," croaked Caglio. He lifted the back of the head. It swung upward, hinged beneath the

shaggy wig. "See this intricate machinery? It is a thinking device. Those wheels act under thought impulses,

"Note the steel ribbons coiled below. They are phonographic records. They produce the voice that you heard.

He closed the head and replaced it in the box. He shut the box and put it on the shelf above the safe. Lifting

the top of the square table, Caglio showed coils and batteries wedged in the upper portion of the pedestal.

"Electromagnetism operates The Head," he affirmed, seriously. "Once the mechanism is charged, it continues

its operation. We might liken it to an adding machine; one devised to complete intricate calculations.'

"Overnight" Caglio paused and pointed to the shelf "the wheels will click into new positions. One day

will suffice. Then Zovex will speak again. His lips will utter wise advice. Important problems will be solved."

"That's the lowdown, Cliff," affirmed Squint. "I've listened to The Head pipe the dope I wanted. Me, sitting

here, taking down the tips as fast as Zovex spilled them. Making out a list of it. That's how I swung that job

"Say it was a cinch, the way The Head had it! A setup! And it'll be the same when The Head gives us the

dope on The Shadow. But it's different tonight than it was before. I didn't come here to tell The Head

"This time, we've brought some ideas of our own. Zovex has got to have time to work them out. That's why

CLIFF nodded. He doubted Caglio; and he believed that Squint had fallen for the professor's stall. The Oracle

had impressed Cliff as being a simple mechanical device, set to deliver a limited number of statements. That

Cliff was sure that The Head could not think. He was positive that it could not deliver elaborate statements,

unless some subterfuge should be employed. He knew that he would have to wait until the next night to learn

what trick Caglio intended to use. Cliff was willing to wait. That was his purpose here.

Cliff's nod was intended to indicate belief in Caglio's statements. The professor was bluffed, along with

Squint. Caglio's next action was designed purely to add new conviction. He conducted Cliff to the automatic

Actually, Cliff was a competent chess player; but knowledge of the moves of pawns and rooks did not fit his

"Perhaps you have played checkers?" Cliff nodded in response to this question. Professor Caglio produced a

quantity of pawns and arranged them as checkers on the board. He also stacked a heap of flat metal rings.

"The automaton can play a checker game," declared Caglio. "When kings are made, simply drop a ring over

the knob of the pawn. Use the pawns as checkers. But not until I have arranged the mechanism."

He opened the doors, one by one, closing each before he opened the next. With each action, Caglio made an

adjustment of the machinery both inside the figure and in the oblong box upon which the automaton was

The automaton, playing with slow precision, outguessed its human opponent. Cliff had as bad luck at

checkers as Hal Rydler had experienced at chess. Caglio smiled triumphantly when the game was over.

"This demonstration proves my point," declared the professor. "You have seen the skill of the chess player. It

outmatches human intelligence. It is trivial, however, with the processes produced within the head of Zovex. I

"Come. We shall return to the study. I shall summon Marley to conduct you to your rooms. You may forget

The Shadow while you are within these walls. This house is a fortress. No human being may enter it without

CLIFF was pondering when they reached the study. The performance of the chess player had baffled him. It

seemed to support Caglio's statements regarding Zovex, incredible though the claims might be.

Marley arrived and led the visitors upstairs. They entered a hallway that led into a central passage like the one

downstairs; except that there were fully a dozen doors, some reached by short side passages that led off from

the main one. Marley ushered Squint into one small bedroom; then conducted Cliff to another, on the

The room was lighted; but its ceiling added a silvery tinge. Looking up, Cliff saw that it was paneled with

skylights. The silver hue was moonlight. All the skylights were fixed in position by heavy frames. These

Cliff did not attempt to open a skylight. Instead, he performed a simpler action. He brought an envelope from

his pocket and carefully unfolded it. The edges retained dried mucilage. Cliff moistened the borders of the

envelope; then stepped upon a chair and pressed the flattened paper against the lower surface of a skylight.

OUTSIDE the squarewalled building, all was silent. Gray walls loomed forbidding, save for the sparkle of

granules in the stones. Set in its lonely clearing, this house of mystery formed a forgotten structure lost amid

No watchers were on duty. There seemed no need for them; and there were no windows from which lookouts

could have peered. Hence no one saw the strange phenomenon that occurred beneath the moonlight.

A shape emerged from the blackness of the tree that fronted the house. A stalking form, it moved with

uncanny glide. Moonbeams revealed it as a shrouded figure cloaked in a habit of black. It was The Shadow.

The sablehued arrival reached the front wall of the house. His form merged with the shaded stretch beneath.

The moon had risen beyond the square house. Here, at the front, the lunar glow was blocked. The Shadow

Looking upward, he could see the bulges of the wall. Protuberances showed against the silvered sky. Slight

though they were, those projections offered footholds to The Shadow. When he essayed a smooth surface,

The Shadow used rubber suction cups; those devices would be useless upon irregular stone. The roughened

His ungloved fingers found cemented spaces. His toes, encased in softtipped canvas shoes, were equally

adroit. Invisible against the single darkened wall, The Shadow began his upward course. Like a mammoth

Moonlight, bathing the top parapet, produced a sudden sparkle as The Shadow's hands arrived upon the

ledge. The rays had caught the girasol; the gem was glinting from The Shadow's finger. Then the cloaked

Crouched upon the broadtopped rail that girded the roof of the strange house, The Shadow formed a ghostly

figure against the pale sky. No one could spy him from within the house. There were none outside who might

The Shadow was a ghostly visitant a specter that seemed conjured from another realm. His presence added

to the sepulchral tenor of this outlandish abode that stood within the woods. The house itself was like a

mammoth tomb; The Shadow, a spirit that had chosen a resting place upon its summit.

The final visitor had arrived. Unseen, unsuspected, The Shadow stood ready to plan a foray into the strange

The roof presented an odd appearance when viewed from the parapet. It formed a floor plan of the second

story. The reason was that the rooms alone had skylights. The passages of the second floor were topped by

The Shadow studied this arrangement, viewing it clearly by the moonlight. A long, wide stretch ran from the

front of the roof to the back; there it turned to cover the passage to the stairway. All along the central path

were blocky projections. These indicated the short side passages that led to rooms on the second floor.

There were other wide streaks also. The Shadow noted that they were nearly as broad as the paths that

represented hallways. These indicated the walls between the rooms on the second floor.

As for the rooms themselves, they were easily located by the skylights. They formed blocks, placed regularly

about the roof. Each square of skylights was divided into smaller sections, like a portion of a checkerboard.

The roof offered easy access, for it was a level floor only three feet below the gray granite ledge whereon The

Shadow rested. Yet the cloaked figure made no immediate attempt to reach the roof. Keen eyes were studying

The roof was striped with burnished copper that shone like old gold in the pale moonlight. The solid

pathways had closeset streaks, each a few inches in width, to form a corduroy surface. Thus each solid

The square ends of the skylights had teninch frames between them. These were also of a corduroy

formation. This arrangement, coupled with the choice of metal, told The Shadow why the roof had been so

The entire surface was a barrier that would stop entrance from above; and would also prevent exit from the

rooms on the second floor. Those copper strips were charged with electricity. To tread upon them, unaware,

THE SHADOW had been favored by the presence of moonlight. The fact that the copper was new and

untarnished had also aided him to spot the snare. It was a long stretch to the nearest block of skylights; even

if he used the glass panes as stepping stones, The Shadow would be handicapped. Each pane was but little

larger than a man's girth. To pry at one, contact would be necessary with the copper strips that fringed it.

There was a way to navigate the roof, however; and The Shadow had the means with which to accomplish the

task. From beneath his cloak he produced a flat stack of rubber disks, that made a compact bundle. These

were his suction cups, each six inches wide and concave on the bottom surface. The Shadow girded his cloak

Deliberately, he dropped inward from the parapet and stalked across the roof, keeping to the solid portions.

Only the rubber disks contacted the burnished copper. They acted as insulators. No current could pass

His tread was squdgy; but the twisting pressure of his feet enabled him to lift the disks with every step. The

copper strips were slippery; moreover, there were ridges on the roof. The spaces between prevented the

Peering toward the various blocks of skylights, The Shadow observed that some were brighter than the

others. Each cluster of illuminated glass meant a lighted room beneath. The Shadow counted four such

It had sixteen small panels, each a scant two feet in width. One skylights showed a peculiarity. There was a

black patch in its very center. Some object had been plastered on the lower side of the glass.

A whispered laugh told that The Shadow had divined the purpose. He had found the room that Cliff Marsland

occupied. The blot that cut off the lower light was caused by the envelope that Cliff had pressed against the

STEPPING from the solid portion of the roof, The Shadow shifted to the frames between the skylights. He

stooped; his right hand rested upon a framework. The disk upon The Shadow's hand acted like those upon his

feet, serving as a protective insulation. His left hand came free from its disk; his fingers tapped the glass of

Inside the room, Cliff had noted the blackness above the glass. His answering taps came promptly. With

quick raps, The Shadow and his agent communicated. Their messages were dots and dashes in a special code.

The Shadow was ready to effect entrance to the room below. He wanted to know if the interior was guarded

by bare wires. Cliff replied in the negative. The Shadow questioned, to learn if Cliff could work at the

The Shadow gave the order to proceed. He waited while the sounds of a working screw driver came from

beneath. Cliff had brought along a few odd tools. Such equipment was natural, since he was supposed to be

The task was slow and laborious, for Cliff was cautious in his operations. At last the skylight moved

downward. Peering through the opening where the pane had been, The Shadow saw Cliff stepping from a

A hissed whisper from above. Cliff placed the thick pane upon the cot. He turned out the light. The Shadow's

form swished downward through the darkness. The master sleuth had gained his goal.

The whisper was barely audible in the darkened room. Cliff gave detailed response. He described his arrival

with Squint Proddock. He told of his first visit to The Head. He expressed his belief that the Oracle was

The Shadow's tone ended Cliff's story. Sibilant instructions followed. Cliff was to wait until The Shadow had

departed from the room. Then he was to replace the skylight and affix its supporting inner frame.

Cliff saw the door open as The Shadow tried it. He caught a glimpse of his cloaked chief. The Shadow was

pausing, with the door ajar. Something about the barrier had attracted his attention.

The inner knob had yielded slightly when The Shadow had turned it. He was studying that factor. The

Shadow pressed the knob inward. It acted like a plunger. Oddly, the knob still operated the latch. The

He pressed the outer knob in plunger fashion. The inside knob refused to turn. The Shadow lengthened both

plungers. Each knob turned with ease. Cliff had drawn close to note the process. He saw the value of the

Cliff had wondered why no doors had locks. He understood at last. Professor Caglio had invented an

ingenious arrangement. Pressure upon either doorknob would act upon the other side. This was a device that

would work two ways. It was possible for any occupant to lock the door of his room. Conversely, any one on

The door was closing. The Shadow had moved out into the hall. Cliff turned on the light and began a careful

SOFT light illuminated the solidroofed hallway of the second floor. Beneath the indirect glow, The Shadow

He was stalking silently along, eyeing each doorway that he passed. He stopped at a portal near the stairs.

This door bore a slight difference from the rest. Its knob was jammed farther inward. In light of The

Shadow's recent discovery, this door became important. The condition of the knob indicated that the room

contained a prisoner. This door alone had been locked from the outside. The Shadow knew that this must be

The Shadow placed his hand upon the knob. He was about to draw it outward when a slight click came from

along the hall. With a quick turn, The Shadow swung from the doorway. He wheeled across the hall and

gained a short passage that led to another room. The click that The Shadow had heard was the opening of a

door. It had come from another side passage. Soft footsteps sounded. Peering from his hiding place, The

Cliff had not met Caglio's niece. Hence he had known nothing of the girl's presence in the house. Martha was

attired in a dressing gown. She was going toward the stairs at the back of the hall. The Shadow saw that she

A muffled groan sounded from across the hall. The girl stopped short. She looked toward the door of Hal's

room. The Shadow watched her while she listened. The groan was repeated, less distinctly than before.

Martha placed her hand upon the doorknob. The Shadow saw worriment on the girl's face.

Slowly, The Shadow moved from the alcove, his tall form casting a long silhouette upon the floor beneath.

Martha was facing the door of the prisoner's room. She was listening intently for new sounds from the man

within. She did not suspect the presence of the tall personage who stood almost beside her.

Those stifled groans had told him of some menace. He could foresee danger for the prisoner. He was

prepared to meet the emergency, even though his deed might reveal his presence to the girl outside the door.

Then, as answer to The Shadow's expectations, came another sound from beyond the locked door. It was a

token that allowed no further doubt. It was the sudden cry of a man unnerved by terror.

A scream that ended in a gurgled wail. A shriek that only quivering lips could have uttered. Though muffled

by the thickness of the door, it told of anguish. The call was a plea for rescue from some inhuman torture.

Hal Rydler had delivered that cry from the gloom. The Shadow had heard the call for aid.

Hal Rydler had awakened from a hideous nightmare. He had opened his eyes, to stare at moonlight flooding

through the skylight of the room. His brain had been in a dazed whirl, its thoughts uncollected. Then had

Dopey, Hal had lain motionless. His groans had ended. Passing seconds seemed like years. Then into the

focus of his vision had come a dreaded apparition. It had loomed suddenly, terribly, from the wall beside the

Livid, with gloating lips, the hideous countenance had thrust itself toward him. Bulging evil eyes had met

Hal's own. In an instant, the awakened prisoner had realized that this was no hallucination. He was face to

As venomous breath exhaled upon him, Hal had phrased his frantic, hopeless cry. Then had come hands from

nowhere. Fingers that Hal could not see; for his whole gaze was centered on the leering visage above him.

Claws had gripped Hal's throat. Their tension had produced that gurgled finish to his shriek.

Hal's own eyes bulged. His lips gasped. He saw murder in the leer above him. The face of Zovex was

fiendish as it had been on that first night when Hal had seen this very head upon the bulky shoulders of the

That was the sentence that The Head's expression spelled; and Hal could find no strength to struggle. Brief

moments were like stretches of eternal agony. Then came the interruption that ended the terrible strain: two

sounds that to Hal seemed hours apart; although actually they were almost simultaneous.

Both were clicks, The first, when some one drew back the outside knob of the door. The second, when the

Zovex heard the clicks. Two actions followed. Though simultaneous, they seemed like the distinct deeds of

separate creatures. Hands left Hal Rydler's neck. The distorted face of Zovex bobbed from view.

Hal heard a muffled click from the wall. Then came a stream of light from the door. With an effort, Hal rolled

outward on the cot. Dazed, stroking at his throat, he sat up. He saw Martha Keswick standing in the doorway.

HAL managed a weak smile. He tried to gain his feet; but failed. He slumped back on the cot; then steadied

and looked toward the wall. He saw nothing but the blankness of the panel. He stared toward Martha and

noticed a blackness that hovered thick beyond the girl. Hal blinked; as he did, the background faded.

"What was the matter?" queried Martha, in a tense whisper. "I I heard your scream..."

"A nightmare!" gulped Hal. "But it was a vivid one. It seemed real! I saw a face that I remembered."

"I saw The Head," he admitted. "It was here, in this room. There were hands, too, that clawed my throat. But

"I must have been woozy," he affirmed. "Never even took my coat off after those two chaps lugged me up

here. All I remember was that my feet must have lead weights tagged to them. I was in the study when I went

"It was odd, too." Hal looked toward Martha, as though seeking an explanation. "The air became stifling

down in the study. First, I was dizzy; then dopey. Does that happen to every one who stops in to see your

"Downstairs," smiled Martha. "I could not sleep because the moonlight disturbed me. I was going down to

the living room to read a book until dawn. If you will come there, I can stop at the kitchen and make the

Steadying himself, Hal stepped from the room. He closed the door behind him; then followed Martha along

The Shadow had edged back into his hiding place; from that point he had heard the conversation. His path

was again clear; but he had found a mission to keep him on the second floor. No occupants of secondstory

rooms had heard Hal Rydler's stifled cry. There was chance to investigate without disturbance.

Hal had closed the door of the room. Martha had paused to push the knob inward. From this action, The

Shadow knew that the girl understood the locking device. Her knowledge of it was not quite perfect,

however; for she had first tugged at the knob, then turned it at the time when she had opened the door. Only

Doubtless, Professor Caglio would call her to task when he learned that she had released the prisoner.

Martha's last pressure of the doorknob was proof that she wished to postpone the time when she would be

called to account. Caglio would not know that Hal Rydler had left the prison room unless the old man

should come downstairs from his own quarters. Hal's closed door would give Caglio no clue to the young

But Caglio would learn eventually; and from that conjecture, The Shadow drew a conclusion. The girl whom

he had seen was probably a privileged person. She had no part in crime, although she probably knew that evil

Because of his conclusions, The Shadow showed no hesitation when he approached the door of the vacated

room. He drew out the knob; then turned it. He entered the room and closed the door. The reason for his

double action with the outer knob was that he might have an exit. The Shadow did not care to lock himself

MOONLIGHT showed paneled walls, as The Shadow pressed the inner knob to prevent the entry of chance

intruders. Keen eyes looked everywhere. The Shadow had heard Hal Rydler's statements. He believed that the

prisoner had actually seen The Head. Hal had spoken, too, of hands. Whence had they come?

Noting the pillowed end of the cot, The Shadow saw a narrow panel of less than eightinch width. Next, a

slight space; then a panel nearly three feet broad. Space narrow panel space broad panel; the

arrangement continued all along the wall. The Shadow concentrated upon the wide panel that was nearest the

Gloved fingers tapped, but their strokes were amazingly light. It was almost as if The Shadow felt the

thickness of the woodwork; as though his testing fingers could sense space beyond. His hands were moving,

groping for the secret of the panel. Each hand found a vital spot. With one thumb at each side of the panel,

The Shadow pressed. The woodwork gave; the panel moved inward several inches then slid toward the foot

Dank air pervaded blackness. The space beyond the panel was not conditioned like the atmosphere of the

room. The Shadow placed one knee upon the cot; then edged across and stooped through the low doorway

that the opened panel had produced. He found the panel, slid it back into place. There was a muffled click

A flashlight glimmered. The Shadow was in a narrow corridor. The thick wall was hollow, but it was lined

with brick, except for the opening that afforded access to Hal's room. The Shadow followed the passage; he

came to another opening in the opposite wall. This led to the panel of another bedroom.

A spiral staircase appeared at the end of the passage. This was in the house wall itself. The Shadow

descended. At the bottom, he discovered a lengthwise passage in the house wall. He followed it, to discover

other metal stairways. The passage reached the front wall of the house. It turned. The Shadow continued his

He had noted openings in the bricks of the inner wall. Calculating from Cliff's description of the ground floor,

The Shadow knew that these must open into the study, the living room, and finally the hall. It was at this last

Probably, there was a similar passage starting on the other side of the shaft. One that could be entered from

hall, dining room or kitchen; with spiral staircases to the second floor. Thus a hidden prowler, starting from

THE SHADOW returned along the passage. He found the opening to the study. He pressed the panel. It slid

aside. The Shadow stepped into Professor Caglio's headquarters. He found a light switch and pressed it.

Illuminated, the study looked quite ordinary. The Shadow had closed the panel; the walls seemed all alike.

There were points, however, that concerned The Shadow. First: the passage had ended with the side opening

Did another passage begin past some blockade? It was possible; for The Shadow had found no opening that

indicated the mysterious corner room that housed the professor's automata, including Zovex.

The Shadow tried the wall. He found a panel near the corner, that gave beneath capable pressure. The oak

moved sidewise. The Shadow saw a cavity that housed a tall, bulky safe. This was Professor Caglio's vault.

Here, perhaps, was where he kept blue prints and models of his various inventions.

The Shadow closed the panel. There was no indication of a passage beginning from beside the safe. The

cavity was thoroughly bricked. If there should be a passage to the Oracle room, it would be found in the wall

Deliberately, The Shadow probed wide panels. Not one broad space of the side wall gave results. The panels

conformed to the usual procedure, alternately narrow and wide. There were five of the broad ones. The

Starting back toward the rear panel, The Shadow paused. He looked toward the wall that lay between the

study and the living room. He decided to test it also. He came to the middle panel. He found that it yielded

To any but The Shadow, the sudden sweep of blackness would have been startling. It might have signified a

sudden danger. But The Shadow remained at ease. Dark was his habitat. He linked two facts immediately.

This panel had a special purpose. For some reason, no one was supposed to open it while the study was

lighted. To insure that procedure, the panel was fitted with a switch that automatically cut off the lights.

To test his prompt theory, The Shadow released the panel so that it pushed toward him, impelled by an inner

spring, like the previous panels that he had opened. The movable woodwork came flush with the wall. The

lights in the study glowed promptly, again revealing The Shadow's cloaked form by the wall.

The Shadow stepped over and pressed the regular light switch. In total darkness, he returned to the side wall

panel. He pressed it inward and slid it to the left. Light greeted him from a broad, windowlike space a few

ONLY glass lay between The Shadow and the scene that he viewed. He was looking into the living room,

through the big mirror that adorned the wall opposite the fireplace. Hal Rydler and Martha Keswick were

This was a contraption with which The Shadow had long been familiar. The glass, silvered by a special

To any one in the living room, the glass would appear as a framed mirror. That situation would exist always,

since lights would have to be on in the living room for any one to study the glass from that side.

Conversely, any one in the wall cavity would always be able to see through the Argus mirror and watch the

occupants of the living room. The cavity was a perfect spy room, so long as one precaution was steadfastly

All light must be kept from the space behind the mirror. Even the flicker of a match might be a giveaway.

The Argus mirror explained the cutoff to the light switch, that ended illumination in the study whenever any

one pressed the panel. That was Professor Caglio's arrangement to prevent a chance betrayal of the secret.

Sound was cut off by the glass. The Shadow saw no reason for silence in motion. He probed about in the

darkness of the narrow spy room. He discovered a folding beach chair at one end. This was for the benefit of

The Shadow stepped back through the opening into the study. He closed the panel. He sought the passage that

led through the main walls of the house. He came to the blockade caused by the elevator shaft. Carefully, he

He could hear voices from the living room; but he was out of sight as he glided past the door of the elevator

shaft. Reaching the panel just beyond, The Shadow opened it and stepped into the passage which he had

THE room that Cliff Marsland occupied was above the dining room. Cliff, awake on his couch, was suddenly

swung to alertness when he heard a hiss from the opposite wall. Staring, he saw The Shadow in the

The Shadow had found Cliff's room. In this case unlike Hal's the opening was across from the cot.

Propped on an elbow, Cliff heard The Shadow's whisper. He stared, astounded by the facts he heard. He

listened to brief instructions; then repeated his understanding in a low, cautious tone.

Cliff saw The Shadow move toward the door; then glide out into the hall. Soon the cloaked master returned.

He had gone to set the outer knob of Hal Rydler's door. The Shadow's figure faded. Cliff heard a slight click

Below, The Shadow appeared again when he came out from the far passage and passed the elevator shaft.

Then he was gone, into the secret corridor that skirted living room and study. This time, The Shadow took the

He had one detail that needed attention: to unlock the inner knob of the room where the prisoner had been.

That accomplished, The Shadow returned below. Again, he entered Professor Caglio's study. He did not turn

on the light. Instead, he went directly to the panel that opened into the spy room.

Stepping beside the Argus mirror, The Shadow closed the opening through which he had come. Totally

obscured by blackness, he indulged in a whispered laugh a prophetic quiver of mirth that was stifled within

these narrow walls. The Shadow had another view of Hal and Martha, as they chatted above their coffee cups.

Finally, The Shadow stretched out in the beach chair. His whisper came like an echo of his former thoughts.

Here, in the midst of Professor Caglio's abode, The Shadow had found a headquarters of his own. From here

he could issue forth to new forays; and try again to find a secret entry into the room where Zovex might be

No space could have been better suited to The Shadow's needs than was this spy room. It extended past the

end frames of the glass; hence either extremity of the space would serve a hidden lurker, should Caglio or any

Moreover, the presence of the Argus mirror meant that no light would be introduced into the spy room. With

no thought of a bold intruder hiding here; with no illumination to reveal a silent, watching form, the old

Through keen ability, The Shadow had penetrated to a spot where he would dwell secure. He could watch the

living room; he had access to Caglio's study. Entrenched in a strategic position, The Shadow could remain.

Unseen, unheard, his very presence unsuspected, this master sleuth would await the time for action. Hal

Cliff Marsland and Squint Proddock were seated by the fireplace in the living room. Opposite them was Hal

Rydler. Cliff and Squint had just finished a trivial conversation. Hal was reading a book; he had scarcely

With the lull in conversation, Cliff reviewed the events of today. He had risen early; he had come downstairs

to find Hal and Martha talking in the living room. Having met neither one before, Cliff introduced himself.

Professor Caglio had arrived next. He had been surprised to see Hal; but had quickly recovered from his

puzzlement. Hal had mentioned that he had slept poorly; and Martha had added an explanation.

"It was the moonlight, uncle," the girl had said. "Mr. Rydler was troubled by bad dreams. I was passing his

Squint Proddock had joined them for breakfast in the dining room. An uneventful morning had followed.

Then lunch; now, afternoon. They had been in the living room constantly, except for the intervals at meal

With the day dwindling, Cliff knew that The Shadow had kept watch all the while. From his cloaked chief,

Cliff had heard the secret of the Argus mirror. Cliff could almost sense keen eyes, peering from a perfect

watching place. Yet Cliff found it difficult to curb impatience. He had the urge for action.

A clock was chiming six when Professor Caglio and Martha entered the living room. They were followed by

Marley. The glumfaced servant was carrying wood to build a new fire, for the old one had gone out, hours

"I have the model prepared," declared the professor, wisely. "Selfridge is ready to give us a demonstration.

"I was the one who wished to see the model," put in Cliff, quickly. "You say it is ready, professor?"

Caglio showed a pleased smile at Cliff's quickness to fill the stopgap. Cliff arose, made a sign to Squint,

Cliff followed Caglio through the hall, where the permanent, mellow light pervaded. They entered the study.

As soon as the door was closed, the professor clamped an approving claw upon Cliff's shoulder.

"Timely work, Marsland!" clucked Caglio. "I thought that Proddock would catch the idea I gave him. That I

"Squint's slow, sometimes," he rejoined. "He ought to have got the drift of it; but he didn't. That's his way."

"But you were doubly alert. You saw that I wanted only one of you to come with me."

"Right. I could not count on Marley stayin' there indefinitely. I wanted either you or Proddock to remain."

"Marsland," he stated, "young Rydler is of no use to us. I intend to be rid of him. Unfortunately, my niece has

befriended him. Therefore, I cannot harm him at present, unless some emergency should render it necessary."

"Martha was here for a purpose, though she did not realize it. Originally, Zovex acted only as an Oracle, to

tell the fortunes of society folk who came here. Martha entertained the visitors."

"I get it," grunted Cliff. "The moll was the front for a spook racket. How was the take, prof?"

Caglio smiled at Cliff's slang. He was convinced that The Shadow's agent was a product of the bad lands.

"It was quite large," declared the professor. "But since Zovex has changed his policy, the receipts have

"Squint told me," answered Cliff. "Fiftyfifty. Zovex is the brain. He uses fellows like Squint and me to stage

the jobs. We deliver the swag. It stays here so Zovex can figure a way to fence it. We get our cut later."

"Yes. When it is safe. Very well. There is always the chance that we may be investigated."

"Yes." Caglio smiled, sourly. "Zovex, however, had prepared for such an occurrence. Every worker is

covered during his act of crime. Nevertheless, some one might visit this house some one not wanted "

"Yes. A sleuth expecting to find a supercriminal. But what would he find? I shall tell you. Nothing but a

talking head! An automaton that can be examined. A device once used for telling fortunes."

"Never! Because I asked no fee for Zovex's services. Wealthy persons sent anonymous contributions. But no

"I get it. The moll your niece she'll back that story. That'll crimp any wise district attorney who wants to

"Exactly! Any trouble must be quickly squashed. I shall tell you why, Marsland. The mechanical brain of

"They talked a great deal to Zovex. He learned of many private subjects, that concerned money and its

"Our basic policy," reminded the professor, "will be to bring my niece to a state of quietude, with all her

suspicions gone. Once she believes that Hal Rydler is free from danger, Martha will again be useful."

PROFESSOR CAGLIO was drumming the desk top as he spoke. Cliff could see that the old inventor was a

capable analyst. Caglio had covered the situation well. His policy was obviously planned to cover up the

future, as well as the present and the past. Yet Cliff could not picture the old man as the actual plotter.

Cliff wondered; and with the thought came new speculation regarding Zovex. The Head had looked

mechanical. Cliff had so described it to The Shadow. But there were reasons why it might be real.

Caglio's own actions indicated that The Head must live. The professor's explanations of the Oracle's

mechanism had been glib ones. He had bluffed both Cliff and Squint last night; yet, today, Caglio was talking

straight. So long as his speech did not concern the secret of the Oracle, Caglio lacked guile.

This made Cliff believe that the old man's actions had been ordained by some master whom Caglio himself

Even as Cliff pondered, the answer came. Caglio was studying Cliff's countenance. It was a poker face that

gave the old man no inkling of Cliff's own thoughts. Caglio knew only that his companion was engaged in

speculation. Admiring Cliff's keenness, the old man suddenly became confidential.

"I mentioned a model of an invention," cackled Caglio, leaning forward. His eyes were alight and wide. "My

invention! My masterpiece! Hehhehheh! Few eyes have seen it. Yours will be privileged.

"My invention" his tone had become a croak "will revolutionize industry! It will give me commercial

mastery of the world! The ways of mankind shall some day follow my dictates. Why? Because human beings

"Zovex is a brain." Caglio grinned, cunningly, showing his stumpy teeth. "I shall count upon him as my

adviser. I shall harness my mechanized controllers to machinery everywhere. Power plants, steamship

engines, printing presses all will become perpetual when controlled by my master device. It shall be the

A clucked laugh trailed from Caglio's lips. The old man arose behind the desk and wagged a bony forefinger.

"Later, I shall show you the Caglio controller. You are a man who would recognize its potentiality."

Cliff understood at last. Caglio was a victim of the mania so common to inventors. He believed that he had

solved the impossible. He had been working on a device to produce perpetual motion.

"For years I have endeavored." Caglio's finger was still wagging. "I have approached the threshold of

success. A brain greater than my own has approved my efforts. I have gained encouragement from an

The old man had reference to Zovex. Cliff knew the hold that The Head had gained. Caglio had become the

Oracle's tool because of his own urge to complete his impossible invention. Zovex had gone in for crime.

Caglio had aided willingly; not because he had a lust for evil, but because nothing, good or bad, could stop

Zovex had humored Caglio. The professor had returned the favor. He owned full fealty to The Head.

HOW far Caglio would have followed his present tangent, Cliff never learned. Amid the trail of the

professor's maddened cackle came an interruption. It was a knock at the door of the study. Caglio recognized

Havelock came into the room. The chauffeur was wearing cap and gloves. He had evidently come back from

a trip in the big roadster, for he was carrying a folded newspaper beneath his arm. Havelock's face was

"Look at this, professor." He spread the newspaper upon the desk. "It's about Pinky Garson. He was in an

"Nobody had anything on him," reminded Havelock. "He was just going through on his way South, when he

smacked that taxi under the Sixth Avenue 'L.' He must have bounced off and hit a pillar. He's in a hospital.

"He has not recovered consciousness," remarked Caglio, studying the newspaper. "There is a chance, though,

"That's just it," agreed Caglio. "And if he don't know where he is, maybe he'll say too much!"

"Go back to the living room," urged the professor. "Engage the others in conversation. Tell Proddock that you

admire my invention. Say that I shall let him see it later. That will give me a chance to talk with him."

As Cliff strolled from the room, Caglio followed. Cliff saw the old man press the outer knob. Caglio pointed

frontward. Cliff went to the living room. As he entered the door, he glanced sidelong and saw Caglio stepping

in the opposite direction, toward the door of the room where he housed his automata. Cliff guessed that

ONCE inside the living room, Cliff had a mission to perform. He knew that The Shadow had not overheard

the conversation with Caglio. The Shadow could not have opened the panel from the spy room, for that

would have extinguished the lights. It was Cliff's job to pass word. He had a way to do it. He nodded to

Squint Proddock; then strolled to the big Argus mirror. In nonchalant fashion, Cliff began to adjust his

"The prof has a swell invention, Proddock," remarked Cliff. He avoided the nickname "Squint," because Hal

and Martha were present. "It ought to bring a lot of money. All it needs is a promoter."

"What's the invention?" queried Squint. He had caught on to the bluff this time. "Did you see it work?"

Cliff paused. His eyes were moving. Left straight upward downward. Letter by letter, Cliff was spelling

a message. It was a system that he had learned from The Shadow: speech through motions of the eyes. Slight

head tilts added to the code. Cliff was a slow speller with the system; but he managed his first message:

"You'll see it later." Cliff had brought a comb from his pocket. Using the comb in front of the mirror, he

Cliff turned away from the mirror. He pocketed his comb and sat down to talk with Squint. He knew that The

The door of the living room opened immediately afterward. Professor Caglio entered. Smiling benignly, he

closed the door. He noted that Marley, the servant, had gone. Caglio addressed the others:

"Dinner will be at seven o'clock. I notice that Marley has gone to prepare the meal."

FROM behind the Argus mirror, keen eyes had noticed the professor's lips. The Shadow, already cognizant of

Cliff's message, could also see that Caglio intended to remain here. The professor was just inside the closed

The Shadow stirred within the spy room. He had the right opportunity to enter the study, knowing that Caglio

had not returned there after his visit to Zovex. The Shadow opened the panel. Darkness greeted him; but as

soon as he had gained the study and closed the panel from that side, the lights came on again.

The newspaper was on the desk. The Shadow eyed the headlines. He saw the news about Pinky Garson. The

crook was in a New York hospital. As The Shadow read, he detected a sound. It came from beyond the wall

The Shadow sprang across and listened by a narrow panel. It was from that spot that the noise came most

plainly. A scuffling; a slight scrape; then a thump. A click, like that of a doorknob.

Swiftly, The Shadow reached the light switch and extinguished the glow in the study. He placed his hand

upon the doorknob, intending to open the barrier and peer into the hall. Some one had left the room where

The doorknob would not turn. It was locked from the outside. The Shadow turned on the light and made for

the rear of the room. He gained the hidden passage that skirted the living room. Though silent in tread, he was

speedy. He arrived at the end of the passage, at the elevator shaft. He heard a rumbling sound. The elevator

The Shadow had arrived too late. Some one, coming from the automata room, had gone along the hall past

the closed door of the living room. That person had already descended to join Havelock in the roadster. There

The Shadow returned to the study, via the skirting passage. The lights went out as he entered the spy room.

They came on again, after the panel closed. Ensconced behind the Argus mirror, The Shadow viewed the

Whispering lips chilled the tiny chamber wherein The Shadow stood. The exit of a dweller from the automata

room was to The Shadow's liking, even though he had failed to see the one who had departed. Actually, The

Soon he would have a chance that he had purposely postponed: a visit to the room wherein the Oracle dwelt.

The Shadow would later form his own conclusions regarding Zovex, The Head that lived!

Joe Cardona, acting inspector, made the statement from behind his desk at police headquarters. His words

"Pinky was," admitted Cardona, chewing at the stump of a cigar. "You're right on that guess, Burke. But

"Why should I? Markham here talked with him just a little while ago. Pinky was conscious for five minutes,

Reporters shuffled out, Cardona smiled. He had bluffed Clyde Burke, sharp news hawk of the tabloid Classic.

Markham started to speak. Joe motioned for silence. He wanted to be sure that the reporters were out of

"Pinky wants to talk to you, Joe," informed Markham. "Says he'll only talk to you alone."

The dashboard clock showed seven when the police car stopped in front of a small hospital near Sixth

Avenue. Cardona entered alone. He encountered an interne, showed his badge, and was conducted to a tiny

CARDONA entered the room. The interne closed the door from the outside. Pinky Garson, head bandaged,

"You're a squareshooter, Joe," whispered Pinky. "Wisht I'd been the same. I oughta stayed straight."

"Yeah. I did. But I slipped back. I'll tell you how and why, Joe if you'll promise to do something for me."

Pinky's glazed eyes saw friendliness in Cardona's gaze. The dying man motioned for another sip of water.

"It's this, Joe," he affirmed. "I had two keys on me. The interne's got 'em, I guess. Both are to safedeposit

boxes. In the same bank. You'd have trouble finding the bank and learning the name the boxes are under. I'll

He gave Joe the name of a bank in Cleveland, and the name under which the safedeposit boxes were held.

"Listen, Joe." Pinky was pleading. "One box has dough that's mine. Twenty grand, that I'd built up out of

good investments. I gotta couple of kids, in Cincinnati. I ditched 'em years ago. The dough's for them, Joe.

"They say crooks have pals. That's the bunk. Every crook's a rat! I'm a rat! I'd doublecross a dying pal!

That's the kind of a mug I am. The only decent guys I've ever met was the fellows I done dirt to. Fellows like

"That's why I wanted you to come here I don't want no rat to get the mazuma that I made when I played

straight. It's for the kids. If you say they'll get it, I'll die knowing they will."

Pinky paused. His eyes closed. He was awaiting Cardona's reply. Joe's answer came low, but emphatic.

"The money goes to the kids," assured the ace. "Tell me about the other deposit box, Pinky."

"This'll throw you, Joe," he said. "Y'know what's in it? Some of them bonds that Threed shoulda got. I was

the guy that staged that job, Joe. I turned 'em over to The Head. He kept more'n half o' em; but wanted me to

"I know what you're thinking, Joe," the dying man. "The dough ought go to Threed, too. It ought to make for

"Sounds screwy; but it ain't. Zovex is The Head. He's a konk with a clockwork brain. And The Head is smart.

"I get it." Cardona nodded, as Pinky sank back and closed his eyes. "I can go in and out as Tony Darelli."

Cardona waited a few minutes; then departed. Downstairs, he asked for Pinky's effects and received them. He

found the safedeposit box keys in an envelope. He handed the latter to Markham, when he had joined the

LIGHTS were gloomy in the downstairs corridor of the secluded hospital. The interne had left the office. On

the ledge lay a sheet of paper with a notation referring to Pinky Garson and the dying man's room number.

A strange sound came from the hospital entrance, a dozen minutes after Cardona had gone. It was a thumping

succession of footsteps. Into the dim light clumped a horrendous figure. It was the squareformed creature

The monster was wide and bulky. Limbs and body were thick and rounded. Its arms extended oddly, hanging

short from squarerigged shoulders. Heavy, clumsy gloves covered the hands. Above the thicksweatered

body was a downturned head, its features lost below the visor of a pulleddown cap.

The clumping visitor stopped by the window of the office. He saw the paper that bore Garson's name. With

an evil snarl, the fiendish creature thumped toward the stairs. Upward it went with steady, heavy footsteps. At

A nurse had heard the sound and was standing in the hallway. She could not locate the direction from which

the thumps had come. The nurse went along the corridor. Peering from the stairway, the clumper saw her

departure. He moved forward and reached Pinky Garson's door. He opened the barrier and entered.

Pinky was lying with closed eyes; but his ears sensed the thumps as the figure thudded up beside the bed. An

interval followed. Pinky opened his eyes. His half smile faded. His lips gasped. All that Pinky could see

before him was a face. He recognized that fiendish, leering visage with its gloating leer, its squatty nose, its

VENOMOUS eyes saw Pinky's consternation. Evil lips phrased grating words that were as nothing human:

"I I couldn't help it!" gasped Pinky. "It it wasn't no squawk. Honest, Zovex! I didn't think you could come

"I I wasn't sure. I was croaking; I had to send for a pal. Honest, it was a pal I talked to! Tony Darelli, from

he had seen the face he dreaded. The past had surged through Pinky's brain. He had quailed, unable to resist

snare soon after The Head returned to find him at the windowless abode. Death would be designed for Joe

Dinner had begun at Professor Caglio's. The meal had been delayed, probably through some fault of the

servant Marley's. Hence the clock in the living room was chiming half past seven when the expectant diners

The Shadow, watching through the Argus mirror, saw the last of the throng depart. He turned about and

opened the panel to the study. He stepped into the silent darkness. Light came on as The Shadow closed the

This was The Shadow's hour of opportunity. He had delayed in order to make sure that Caglio would not

return to the study. Knowing that the old professor would be at dinner, The Shadow had time to operate.

His first goal was the narrow panel on the other side of the study. It was there that he had heard the sounds

from the automata room. The Shadow knew that there must be a hollow space beyond the narrow panel.

He had not learned that fact upon his previous investigation. That was because he had tapped the broad panels

only. All other special panels had been wide ones. This narrow space was inches, only. It could not serve as a

way to a regular passage. In view of present circumstances, however, the narrow panel demanded survey.

The upright strip opened under proper pressure. It slid aside. The study lights revealed a space between brick

walls. It was a cleft straight through to the next room, with another barrier at the other end. The space was

The Shadow could not squeeze his shoulders through it. Nor could he manage to reach the barrier at the other

end. He had found a passage to the room that he wanted to reach; but the avenue was useless.

The Shadow closed the panel. He tried the door of the study and found it locked from the outside. He took to

the roundabout passage that skirted the living room. He came to the end of the elevator shaft. Cautiously, he

From the end of the hall, The Shadow could see into the dining room. Professor Caglio was seated at the head

of the table, with Martha on his right and Hal on his left. Cliff Marsland was seated next to Martha. Squint

Marley entered from the kitchen. The servant was carrying a platter. Martha took a helping; then, the

professor. While the old man was engaged, The Shadow edged out into the hall and closed the panel. Neither

Caglio nor Marley saw his advent. As for Hal and Squint, their backs were toward the hall.

If Cliff saw, it would not matter. The Shadow was running a risk only so far as Martha was concerned. As it

happened, Cliff did not spy The Shadow. But Martha, chancing to look toward the hall, caught a full view of

THE SHADOW saw the girl's stare. He had closed the panel. Martha did not know whence he had come. For

an instant, burning eyes were focused from a distance. Then The Shadow had swept noiselessly along the

Martha blurted a cry of surprise. Cliff looked toward the girl and saw the direction of her gaze. He knew that

Martha had seen The Shadow. With quick impulse, Cliff scuffed his chair backward and snatched at a glass

of water that was near Martha's plate. His action caused the others to look toward him. Martha looked with

"You will excuse me, Miss Keswick. I don't blame you for being startled. I almost toppled that glass of

made. She thought the incident of the glass was a chance one. It gave her time, however, to regain her

Martha knew that this house held secrets. She had seen the Oracle; she had guessed that there was a lurker

here whom she had never seen. Hal's experience had added to her belief. Sight of The Shadow had startled

her but momentarily. Her conclusion was that the cloaked shape must be identified with Zovex. The girl was

IN the hallway, The Shadow had passed the door of the study. He stopped at the door of the automata room

and found the knob pressed inward. He turned it. The door opened. The Shadow gained his first entrance into

The Shadow had known that this door would ordinarily be locked from the inside. But since some one had

departed from the room, he had inferred that it would be locked from the outside only. In order to be sure of

later exit, The Shadow pulled the outside knob outward. Then, in the room itself, he closed the door behind

The Shadow noted the mechanical chess player and the dolllike writing figure. He passed beneath the cages

with their artificial birds. He saw the boxes of heads upon the shelf. He picked a closed one and opened it.

The Shadow studied the leering face of Zovex. The bulging eyes were glaring, despite their glassiness. The

Shadow removed The Head from its box. He studied the surface of the evil, Vlined face. It was not ordinary

waxwork; nor was it an embalmed head. The Oracle was made of some peculiar composition that possessed

The Shadow opened the back of the head and examined the interior mechanism. He tested various levers, set

them; then placed the head upon the squaretopped table. The Shadow waited. The lips began to move. They

Lips stalled. The Shadow jogged the table. An interval; the lips moved again. They stopped. Eyelids dropped

with a slight click. The Shadow lifted the head, opened it again and made another inspection. He pressed a

There were six roller ribbons inside the head. The Shadow counted them; but made no test. He knew that they

acted as phonographic records. He saw no reason to make the head speak. He replaced the automaton in its

The squaretopped table interested The Shadow; for it was there that the head had rested, according to Cliff's

account. The Shadow removed the top of the table. First, he studied the top itself.

It was formed of nine squares, each about six inches across. These were grooved together to form a solid top.

They were held compact by a foursided border, that added six inches to each edge. Thus the entire top

That space was considerably more than the pedestal, which The Shadow estimated to be twenty inches square

at the top. The Shadow saw the array of batteries nestled in the pedestal. He removed them. The pedestal

narrowed downward on the outside. Viewing its interior, The Shadow saw that the cavity tapered in similar

The Shadow tested the batteries. They were dead. Caglio's explanation of electromagnetism was sheer bunk.

WITH a whispered laugh, The Shadow replaced the bordered table top. He had learned one fact. He wanted

another. He went to the waxwork chess player and opened the door in its chest. He also unclosed the two

doors in the supporting oblong box. He saw the array of interior levers; but he needed his flashlight to make a

By the glimmer of the little torch, The Shadow studied the machinery. The levers were not thickly placed; for

he was able to extend his arm up through the hollow body of the chess player. A glow shone through the door

in the figure's chest. The door was merely a light framework, its front stretched with cloth.

The Shadow extinguished the flashlight. He walked about the room, tapping at every panel, broad and

narrow. The only one that opened was the panel that connected with the cramped passage into the study.

All that The Shadow found inside was a long box that looked like a carrying case; but there was room for

other objects, if required. The Shadow opened the carrying case. It was empty. It had plushlined sections;

It was easy to see that the box had contained cylinders of various lengths and widths. If hollow, larger

cylinders could have held smaller. This was likely for, beside the box, The Shadow found fiber wedges. With

large cylinders inside small ones, these plugs would prevent the interior tubes from rattling.

The Shadow shut the carrying case and closed the safe. A repetition of his lowtoned laugh told that his

inspection was concluded. The room was as The Shadow had found it. He made his exit into the hall. He

Instead of returning toward the front end of the hallway, The Shadow chose the stairway to the second floor

He had seen every one in the dining room, except Selfridge. It was likely that the technician would be in the

garage during Havelock's absence. The second floor proved clear, and The Shadow chose a room on the

livingroom side of the house. He found its secret panel and descended by a spiral stairway to the study.

The Shadow crossed the lighted room and stopped at the panel to the spy room. He had accomplished his

intended purpose. He had visited the room where Professor Caglio kept the talking head. For the present, The

JUST as The Shadow pressed the panel to produce darkness, his ears caught a click. It came from the door of

the study. It meant that Professor Caglio had returned from dinner. The warning sound was the old man's pull

upon the outer knob. Methodically, Caglio was following the sensible procedure of assuring himself an

Had The Shadow paused one instant, Caglio would have discovered darkness when he entered the study. The

Shadow's plans would have been crimped. But, to The Shadow, the warning click was an immediate spur to

quickness. He swung into the spy room and closed the panel behind him. Lights were on again at the moment

Behind the Argus mirror, The Shadow saw the diners returning to the living room. Cliff Marsland strolled in

front of the mirror and glanced at his reflection in the glass. Cliff's eyes moved, choosing varied directions.

All was well for the present. Cliff would be on watch, ready to give word of any important event that he

might notice. He was counting upon another trip to the closed room. Cliff expected that he and Squint would

soon as his agent anticipated. For The Shadow had learned new and deeper secrets through his visit to the

Strange events would soon be due. The Shadow was prepared for them, now that the last interlude was ended.

The master sleuth had completed plans of action. They might alter, however, should chance compel it.

It was well that The Shadow had made such allowance. Within the next half hour, he was to be faced by

Martha Keswick seemed very weary, as she seated herself beside the fireplace. The Shadow could see that the

girl was drowsy. Several minutes passed; Martha suddenly roused from her stupor. The Shadow saw the girl

rise and speak. He read her lips. She was stating that she planned to go upstairs and nap.

Apparently, Martha had decided that no harm would befall Hal Rydler during the evening. Cliff Marsland

and Squint Proddock had played their part as guests. Cliff, through his natural courtesy; Squint, by saying

Shortly after Martha had left, Professor Caglio entered. He noticed that Hal was reading a book. With a slight

The three strolled from the room. The Shadow knew that they were bound for the professor's study. He would

hear from Cliff later. That assumption was correct; but The Shadow's contact with his agent was to come in a

He stepped to the panel on the living room side. He opened it; the study lights did a quick blackout. The

"Step forward," ordered Caglio. "Wait here until I return. Watch through the mirror.

"Ain't this the hot one!" declaimed the crook. "Say I'd never have guessed that the mirror was a phony!"

"Stick close to the center," suggested Cliff. "Keep watching for Tony to show up."

Cliff knew that The Shadow was here in the darkness. He added information that he knew his chief would

"Pinky must have talked to Tony Darelli," remarked Cliff. "The prof is wise, though, having us here to look

Tony over. Here's the prof coming into the living room. I guess Selfridge is on his way up with Tony."

The sentence ended with an oath. Squint followed with a harsh whisper of recognition:

"The mug's got crust!" added Squint. "Say Pinky must have spilled something and then croaked! So he calls

"Yeah," nodded Squint. "And Joe's wise that this bird is some relation to the guy whose place was cracked.

Cliff's remark was significant. It indicated trouble for the ace detective. Squint gave a chuckle.

"The prof is leaving Selfridge with them," he declared. "He's gone out and he's closed the door. He'll be

SOMETHING gripped Cliff's hand in the darkness. Gloved fingers thrust a wad of paper into his agent's fist.

There was a whisper from the darkness of the study. Cliff and Squint stepped back into the large room. Squint

was talking as the lights came on. The professor heard him from beside the panel.

"It's Joe Cardona!" exclaimed the crook. "Used to be a flycop; now he's acting as an inspector. He's the

"We gotta smear him," added Squint. "Say putting him in there with Rydler was a bum guess."

"Perhaps not," Caglio's voice had returned. The old man had calmed. "It may work to our advantage.

Remember, Marsland? I told you this afternoon that I was prepared for such emergency as this."

"If this detective has brought others," clucked Caglio, "we shall handle him politely; and Rydler as well. But

"Probably," decided the professor. "First, I shall seek the advice of Zovex. I shall visit the Oracle presently "

A rap at the door. Caglio's eyes gleamed. He gave the summons to enter. Havelock appeared.

"Keen work, prof! We figured he'd be here by now. We were looking around when we came in by the drive.

Caglio's cackled statement was emphatic. The professor followed the chauffeur from the room, leaving Cliff

"Looks good, Cliff," chuckled Squint. "Some easy work for The Head, before he figures out how to get The

Seated by the desk, Cliff had opportunity to open the folded paper, without Squint noting it. Cliff read coded

lines in bluish ink. He understood their meaning. Brief instructions from The Shadow. The writing faded. It

was in a special disappearing ink. Cliff let the paper flutter beneath the desk.

Five minutes passed. The door opened and Professor Caglio entered. The old man's face showed a pleased

turn, will see them. Our purpose will be to lull them. Zovex will learn the extent of their suspicions. Their

"You don't have to turn out the lights," observed Squint. "The prof didn't douse them."

"I don't want to take chances," returned Cliff. "He did something at the panel. I'd better be sure."

Cliff turned off the lights. Edging through darkness, he found the panel. He opened it as Caglio had. Light

showed from the living room; then ended as Cliff stepped into the space between and shut the panel after

Quickly, Cliff whispered the news to The Shadow. He told of the proposed visit to Zovex; of Caglio's verdict;

The Shadow spoke in response. Cliff saw his silhouette against the silvered glass. The Shadow was looking

Cliff obeyed the whispered order. He stepped into the darkness of the study. He blundered toward the door, to

find the light switch. Cliff did not close the panel. He had left that to The Shadow.

A muffled click came from the back of the room. Promptly, Cliff turned on the lights. He saw Squint, staring.

"Funny," Squint remarked. "I thought I heard something at the back of the room; like the light switch was

Cliff was pleased. Squint had dropped the subject of that muffled click. It had been a deliberate signal from

The Shadow. The cloaked chief had gone through the study in the darkness. He had taken to the wall passage

that offered access to the upper floor. Cliff had abetted the process, stalling with the light switch until The

Such had been the purpose of The Shadow's message. He had wanted to gain an exit from the spy room.

Cliff's cooperation had aided him. But Cliff had not guessed The Shadow's motive. He would have been

For the second time, Martha was viewing that weird figure. But on this occasion, she was faced squarely by

the eyes that burned from beneath the hat brim. One fearful thought gripped the frightened girl.

Martha was barely able to phrase the terrible name. The Shadow's whisper came in sibilant return.

"Another guest has arrived," pronounced The Shadow. "He is a detective named Cardona. Like Hal Rydler,

Martha nodded soberly. There was a calming quality in The Shadow's tone. The burning eyes brought

confidence. They always did to those who were worthy of a trust. But to men of crime they delivered a fear

"I shall tell him," stated Martha. "He is to insist after he has first talked with Zovex, tonight."

The Shadow had moved backward across the hall. Martha closed the door of her room. She turned to look for

the mysterious being in black. The Shadow was gone. He had merged with the darkness of some doorway.

Martha looked about in vain. She heard a whispered voice that uttered a single word:

Nodding, the girl hastened toward the stairway. As she reached the end of the hall, she caught the tones of a

subdued laugh. It came from unseen lips, a whispered note of mirth that brought a shudder through the

Yet, strangely, the weird mockery did not bring fear to Martha Keswick. Instead, it was an urge; a final

inspiration that gave determination to complete the mission. It was a reminder of the promise that the girl had

Joe Cardona was still talking to Selfridge when Martha Keswick entered the living room. Professor Caglio

had not returned. The girl sat down and found opportunity to speak with Hal Rydler. The Shadow had

foreseen this situation. He knew that Selfridge would be busy making conversation with Cardona.

Quickly, Martha repeated the instructions. Hal looked puzzled; but his trust in the girl was sufficient. He

nodded his agreement. Martha arose and was idling toward the door when Caglio arrived. The professor eyed

He paused long enough, however, to see the girl go upstairs. Then he entered the living room and spoke to his

Hal and Cardona followed the professor to the room at the end of the hall. Selfridge came along. Marley went

by them on his way to the kitchen. The professor opened the door of the end room. Cardona stared about as

"I hope this will interest you, Mr. Darelli," said Caglio, in a polite cackle. "I do not recall the name of the

"A fellow named Garson," returned Cardona, gruffly. "He said you'd know him. Pinky Garson."

"He must have jested," decided Caglio. "'My patrons do not make themselves known by their nicknames. Mr.

"Quite true. Here is The Head. But, as I have explained to Mr. Rydler, it is nothing but a mechanical device."

"Ah, yes." Caglio caught himself. He had chosen the wrong story. "I told you the legends of the theraphim

and the androides. I spoke of the head of Mirme. I said that the theraphim were supposed to be embalmed

"Heads with gold plates beneath their tongues. But this head has no such device. Perhaps you misunderstood

me, Mr. Rydler. I meant that the head of Zovex simulates those that the ancients knew."

Caglio had brought the talking head from the shelf. Cardona and Hal were viewing the evil face through the

opened front of the box. Caglio placed the box upon the table; then removed the head itself.

He opened the back of the head and showed the mechanism. He chortled as he closed the hinged section and

placed the ugly head in its usual place within the box. Shrewdly, Caglio began an eccentric part. He tapped

"Some say that I am lacking here. That is not true. I am a dreamer. I have visioned a mechanical brain. That

may be why people form strange theories. Some think my own brain is incomplete. Others superstitious

"They believe that Zovex lives. That he thinks. They have attached odd meanings to the words that

mechanical lips have uttered. Because of that, I no longer demonstrate the Oracle without explaining the truth

Caglio was beside the table, watching The Head. The lips of the image moved. They grated a reply:

"That is all," he decided. "Come! Look at the automatic chess player. It is a marvelous curio! Ah! The board

Cardona began the game of checkers. He was usually good at the pastime; but tonight he lapsed. Joe thought

the waxwork Turk a poor opponent; moreover, he was constantly forgetting his moves in order to glance

"Heh!" Caglio's chuckle made Cardona stare at the checkerboard in time to see the automaton negotiate a

triple jump. "You are beaten, Mr. Darelli! You made one bad move. That was a mistake."

Caglio motioned toward the door. The visitors filed out with Selfridge. They walked toward the living room,

"MARLEY reports that the sky is clouding," declared the professor. "It will probably storm tonight. Both of

Caglio was shrewd in his gaze. He saw that Cardona was interested in Hal's statements.

"You may both have another interview," remarked the professor. "But I can promise very little more than you

already heard. The device is purely mechanical. You must allow me time to make adjustments."

"All right," agreed Hal. Then, as Caglio turned, "One other thing, professor: a favor that I know you will

readily grant. I'd like to know more about the chess player. Its operation amazes me."

"You forgot to show Mr. Darelli the machinery. I think he'd like to see it. He would realize then how

complicated it is. I suppose, of course, that the figure can be removed from the big chest? To give a better

"The Head is adjusted," he cackled, "but I shall need your aid, Selfridge, to dismantle the chess player. Let us

"I should like to know more about the subject that we discussed last night. Where are my brother's jewels?"

The technician had removed the waxwork figure from the oblong box. The chess player was lying on the

floor, tilted over. The observers saw that it was hollow. They looked down into the oblong box. Hal put a

"Then why such a large box?" asked Hal. "And such a large figure? The player itself contains only a shell of

Without knowing it, Hal was making the same discovery as The Shadow; but without a probe of his own. Hal

was acting as The Shadow had expected. More began to occur in accordance with The Shadow's hopes. The

Shadow had pictured Hal Rydler and Joe Cardona as a competent pair Hal to produce statements that would

"It only took a few minutes to get it apart," remarked Joe. "As I see it, there's only a couple of levers to be

The technician was caught wordless. Professor Caglio glared. He suddenly changed policy.

"We shall replace the figure," he decided. "That is your task, Selfridge. Perhaps you will need Marley "

THE professor stepped over and opened the door to the hallway. He went out to look for Marley; but returned

a half minute later to find that Cardona had already aided Selfridge. The automaton was on its pedestal.

Caglio shouldered forward and pushed the technician aside. He reached in through one of the doorways in the

box. He tugged at a lever. Something snapped. Caglio cackled angrily. He withdrew his hand, bringing forth

"Bah!" announced the professor. "The automaton will not operate. It will be three days before I can replace

"That you broke yourself!" growled Cardona. "I'm wise to your bluff, professor. I don't know your game; but

"Why? because there's too much space there. Plenty of room to hide a man and have him move around "

"I'm not Darelli," inserted Joe. "I'm from New York police headquarters! My name is Cardona and I know the

Selfridge made a spring for Cardona. The technician was whipping out a revolver. Cardona was quicker. The

ace detective already had a grip on his own gun. He jabbed a stubby revolver into Selfridge's ribs and

Hal snatched at Caglio's wrist. He wrenched the professor's hand from his pocket. A revolver plopped to the

floor. Caglio shouted a cry for aid. Men pounded into the doorway with leveled guns. Cliff and Squint had

Cardona stood dumfounded, while Hal grunted a hopeless utterance. And from across the room, the face of

Squint Proddock barked the words. With Cliff Marsland beside him, the narroweyed ruffian was ready to

Cliff Marsland was the speaker. From behind Squint's left shoulder, he jabbed his automatic hard against the

The revolver thudded the floor. Gunless, Squint lifted his own arms. Cliff was grim, as he spoke to Cardona.

"Keep Selfridge covered, Joe. You, Rydler, watch the professor. I came out here, just for this!"

Cardona was amazed. He had known Cliff Marsland as a character in the bad lands. For the first time, Joe

realized that Cliff was on the side of the law. A sudden explanation struck Cardona. The Shadow had been in

Cliff grinned at Cardona's surprise. He was sorry that the issue had been forced for he had long kept the

police in ignorance of the parts that he had played in aiding The Shadow. Some day, Cliff had known, his role

would have to be found out. Only The Shadow was keen enough to permanently play a hidden part. His

Cliff was glad, though, that Joe was the only representative of the law upon this scene. Joe would keep mum.

It came when a rasped tone sounded from across the room. All eyes turned as listeners heard. It was a

venomous utterance that only fiendish lips could have voiced. That snarl was the challenge of Zovex!

THERE was a clatter. As men stared, Professor Caglio cackled an echo to The Head's demoniac snarl. The

box upon the table was hurtling upward, the table top with it, impelled by the spring of swiftly rising

shoulders. Away went the box, to crash upon the floor, bottomless. The table top whirled after it, struck by an

From the pedestal projected a distorted figure that had bobbed up like a jackinthebox. It was a body of

skin and bones, a dwarfish, longlimbed shape garbed in tightfitting jersey. Upon twisted shoulders rested

That head was real! Fullsized, it formed the only normal portion of the monstrosity that had sprung from the

cramped pedestal. The arms, though scrawny, were as quick as whiplashes. Long limbs sped forward from a

sidearm swing. Clawish fists were aiming ready revolvers that Zovex had held within the compact hiding

Zovex was a freak who would have attracted thousands to a side show. More than that, he was a murderer,

ready to put on a swift performance. His itching fingers were upon the gun triggers. He had taken his

opponents unaware; pointblank, he was about to mow down startled men with quick, successive shots.

Hard upon the fiend's snarl came a chilling laugh, that drowned Professor Caglio's intervening chuckle. The

peal of mirth sounded from the doorway. Zovex heard. His bulging eyes saw. His snarl repeated, he forgot all

This climax was one that he had planned. He had learned the secret ways of Zovex. He shared none of the

bewilderment that gripped the others. He had expected this spindly creature to rise from the interior of the

pedestal. The Shadow's investigation of this room had given him every clue he wanted.

Zovex had whipped upward with the flashing speed of a cobra. The Shadow, watching from outside the door,

had barely matched the fiend's swiftness. Zovex had spied him instantly. As the creature aimed, his vicious

were pressed tip to tip. The girasol glimmered from his hand. His right fist was half beneath his cloak, stalled

Shadow's left hand came a vivid flash, with the blinding effect of lightning. A puff of smoke enveloped the

Bulging eyes were dazzled. Scrawny hands faltered. Dazzled by the flash squarely in his path of vision,

Zovex was halted. Then he pressed the triggers. His aim was wide. The fiend's revolvers rocketed their

bullets to the panels on each side of the door. His centering guns had stopped too soon.

Simultaneously, The Shadow acted. His right hand had whipped from beneath his cloak. With a short

Zovex had recoiled with the fire of his own guns. The impact of The Shadow's bullet trebled the jolt.

Backward went the lividfaced fiend, carrying the table base with him. The pedestal thudded the floor. Out

The Shadow had gained the vital edge in this amazing combat. That flash from his finger tips had stopped

The Head's aim. (Note: The explosion from the finger tips, produced by the action of two chemicals, is

terrific in its power. It is extremely dangerous in use; for an overamount, even though seemingly slight, will

produce an explosion with the effect of TNT. The Shadow has used it but seldom; on those occasions, with

the strictest care. Properly produced, the explosion is so instantaneous that the operator remains uninjured.

Because of the danger from these chemicals, I have never made a copy of the formula; and can answer no

requests concerning it. Maxwell Grant.) Hard upon his dazzling stroke, The Shadow had delivered his

SHOTS ripped from the hall. The Shadow wheeled, his left hand drawing a second .45. His new target was

the elevator at the front of the corridor. Three men had arrived. Havelock had come up with Marley. They

were bringing an unexpected newcomer Moose Sudling, the murderer who had left Manhattan.

Jemley's killer had picked a bad time visit The Head. Moose was the first of the trio to taste The Shadow's

lead. The arrivals had fired too quickly. Havelock and Marley regretted it, when Moose sprawled between

Two bullets had found Moose. A third clipped Havelock's gun arm. The chauffeur dropped to the floor,

From inside the room, one man made a frenzied attack. Squint Proddock, snatching up his gun from the floor,

was on the aim for The Shadow. Squint had lunged Cliff aside. Before The Shadow's agent could recover, a

Squint toppled to the floor, his gun jouncing from his fist. Cardona had finished the thuggish killer. Selfridge

was too slow to make a move. Caglio, breaking away from Hal, found Cliff on hand to cover him. Wildly, the

Sight of the slain monstrosity brought a terrible cackle from the old inventor's lips. Cliff and Hal seized him

as he clawed the air and uttered maddened screams. Caglio suddenly collapsed within their grasp and

"He counted on The Head to back him with his impossible invention. We couldn't help it, Marley and I.

Havelock was the only bad one among us. Marley and I played along. But we weren't for it."

Marley was coming into the room, aiding Havelock. Cardona ordered Marley and Selfridge to attend to the

crippled chauffeur. Joe stepped to the hall, expecting to see The Shadow. The cloaked fighter was gone. He

had given an order to Marley; then he had departed. Cardona could hear the rumble of the elevator.

Martha Keswick was standing in the passage from the stairs. The girl stepped forward as Cardona spoke to

her. Looking past Joe, Martha saw Hal Rydler stepping soberly into the hall. The girl gave a choke of

Joe joined Cliff. Together, they stood beside the toppled pedestal. Solemnly, they eyed the dead form of

Zovex. Twisted crazily, long arms and legs outspread, the spidery creature looked like nothing human. Its

overlarge head was tilted back upon the floor. Glazed eyes stared sightless toward the ceiling.

The lips still wore their twist, fixed in their finish of the fiend's last word. The Oracle had made its last

In oracular manner, Zovex had decreed it. Like all evasive oracles, he had failed to specify upon whom the

doom would fall. Zovex had tried to carry out his own verdict, with The Shadow as the victim. Zovex had

The Shadow had completed the decree. He had ended the vile career of Zovex, the monstrous murderer.

Half an hour later, Joe Cardona and Cliff Marsland stood again in the room where battle had been fought.

They had opened the safe beneath the shelf. From its interior, they had brought a medley of objects.

One was the carrying case that The Shadow had found there previously. It was filled with cylinders, large and

small, made of light fiber and stacked together. Stuffed in the case were garments sweater, trousers, shoes,

With the case they had found the mechanical head. They had observed how closely the composition face

resembled the Vfurrowed countenance of Zovex. They had discovered a single square of wood, six inches in

diameter. It was the center of the table top. With it were the batteries that had once been wedged into the

"A great racket," decided Cardona, with a shake of his head. "When the professor flashed the clockwork

batteries. They stayed in the safe. The pedestal was a cinch for Zovex. That spindly body of his could get into

"Even that passage we found, from this room to the professor's study," explained Joe. "A special exit for

Zovex, if he wanted it. No good for anybody else. Nothing wider than a cat could have gone through it.

"Sure! That's what Hal Rydler was telling us. He was fooled when he saw Zovex down at his brother's. He

never would have dreamed that anybody like that could get into the chess player, let alone the pedestal."

"Easy enough for Zovex to work the chess player when he was in it. He did it by putting his hand down

through the hollow arm and looking through that cloth door at the front. Easy to shift around, too, when the

"That was the stunt," he explained. "The top half of his arms made the shoulders, to match up with the big

cylinders around his body. The forearms, dangling, looked long enough for full arms."

"They would," agreed Joe "considering that Zovex had arms that were twice too long for his own body."

HAL RYDLER called from the hall. Cliff and Joe went from the room. They saw Hal pointing into the study.

The top half of the vault beyond the panel contained the model of the perpetual motion machine. Beneath it

were boxes. Selfridge opened them. Cardona saw the green of bank notes; a mass of printed bonds. One small

"This one is too heavy to move," stated Selfridge. "It must contain the stolen gold. Everything is here, sir. If

"It will go easy with you and Marley," interrupted Cardona, catching the gist of the technician's unworded

Martha Keswick answered. The girl had arrived at the doorway and was standing there with Hal Rydler.

"He will think of nothing but perpetual motion," affirmed Martha. "It was only Zovex who could talk him

into other schemes. Ones that were worse than his mania. But I did not know. I thought that The Head was

mechanical one of his inventions. I suspected that some creature lived here. That was all."

"Never! Otherwise, I would have informed the law. The only secret that I learned was the method of

A BABBLE from the stairway told that Professor Caglio had awakened and was coming to the ground floor.

Cardona ordered a departure. They took the cackling old professor with them. Selfridge and Marley brought

Havelock. Before arranging the parties in the automobiles, Cardona drew Cliff to a corner, where they had

"Remember The Strangler of a few years back?" queried Joe. "The one they were after, but never got? He

used to go up ivy vines to the second floor. Some people saw him. He was a burglar by trade."

"And a murderer by inclination," added Cliff. "Zovex was The Strangler? Is that your hunch?"

"It fits," affirmed Cardona. "Hal Rydler saw The Head in his room. He felt a clutch at his throat, just before

the girl came in to help him. It's another reason why Zovex went around in that clumsy outfit. He didn't want

"He was a deep schemer," nodded Cliff. "Getting facts from dupes; then tipping off crooks like Pinky, Squint

"And covering," put in Cardona. "He smeared any tracks that Moose left at Percy Rydler's."

Automobiles rolled from beneath the windowless building. They skirted the house and headed for the road.

They were bound for the town of Littenden, where Cardona could report to local authorities. A drizzle had

As the procession slowed at the outlet to the road, a sound came from the gloom. Cliff Marsland alone knew

its source. It was from a parked coupe hidden off the drive the car that had trailed Squint Proddock when he

The sound was a weird laugh. A tone of finality, from somewhere near the house where horror had held

sway. Solemn, it began as a knell. Rising strident, it changed to a peal of eerie triumph.

It told of hidden prowess, that token of The Shadow. It was the mirth of a master who had solved and ended

the riddles surrounding Zovex. It was a reminder, that taunt, that The Shadow had fathomed every move.

Through Martha's word to Hal, The Shadow had begun the climax. Hal's double request had caused Professor

Caglio to confer with Zovex. To lull the prospective victims, The Head had moved from the chess player to

the table pedestal. Zovex had placed himself where he could not fire from ambush.

Then had The Shadow counted upon the moves of others. Watching, he had known that The Head would be

forced to show his game. In the crisis, Zovex lacked the sure position that he would have had within the chess

player. He had been handicapped, hurling away table top and cubical box. Despite his speed, The Head had

The chilling laugh was a saga a full recounting of The Shadow's deeds. Fading amid the patter of the rain,

the shuddering echoes faded; but their memory persisted within the minds of those who heard.

The Shadow had won the verdict against crime. His triumph laugh predicted that new tasks would follow.
