THE throng from the train gate poured into the vast concourse of the Washington Union Station and melted

away, much to the amazement of Jerry Croft, and to his annoyance, too. He had counted upon staying with

This was his first visit to Washington, and he had heard, but forgotten, that the concourse at the Union Station

was large enough to contain an army of fifty thousand men. At this moment, Jerry felt that he needed about

His walk across to the main waiting room seemed like a oneman parade, and he felt that all eyes were upon

him, until he realized that many of the other people were too far away to identify him, even if they knew him.

In a way, he was lost, after all, but it didn't occur to him, until later, that persons who might have spotted him

The waiting room was large, too, but it was fairly crowded, which was something of a help. Jerry found his

way to the taxicabs, and hailed one just as someone else took it. He turned around and saw the darkfaced

He was an oddlooking chap, as Jerry had noted on the train. Odd, that he had arrived at the cab rank as soon

Maybe he had forgotten something; perhaps he wanted to send a telegram. People did send telegrams from

It was the telegram that had come from Professor Urlich Ardlan, and it was the thing that had brought Jerry

Croft to Washington. Jerry didn't have to look at the telegram to remember it; he knew its brief message by

A cab pulled up and Jerry tossed his small but heavy suitcase into it, as he took another look for the man with

the big, dark brow. Not seeing the fellow, he decided that it was safe to confide in the cab driver, so he told

him to drive to the World Wide Cafe, the meeting place the professor had named in the telegram.

Why Professor Ardlan, whose chief diet was milk toast, should have picked a restaurant as a rendezvous, was

something rather baffling; but then, Ardlan's ways were always curious, and Jerry had learned to expect

Some people insisted that Ardlan was crazy, and Jerry had learned not to dispute them, rather than have

himself considered a bit touched, too. In fact, through association with the professor, Jerry wondered at times

whether he was still wholly sane, particularly when he found himself worrying about men with big foreheads

The cab worked its way to Pennsylvania Avenue, and sight of that broad boulevard, glittering with light,

intrigued Jerry. He was riding away from the capitol building, but in what direction he hadn't an idea, and

when the cab turned off into a side street and swung along another, its passenger was totally confused. The

This, at least, was Jerry's destination. He alighted from the cab, paid the zone fare and entered the restaurant,

carrying his suitcase. A hatcheck girl wanted to take it, but Jerry shook his head and she smiled.

The girl had seen others like Jerry before. He was reasonably handsome, and very earnest, as if he had

important business to handle, with the answer to it in the bag that he carried. He was looking for someone, as

Jerry wouldn't have had trouble finding Ardlan, had the professor been in the restaurant. Professor Ardlan had

much the appearance of a shaggymaned lion, except that his hair was gray, and, in true leonine fashion, he

bellowed at everyone who approached him, which usually meant the waiters when he dined in public.

There was no one in the cafe like Ardlan. Jerry was sure, because he knew that he would have heard the

So Jerry took a table near a corner from which he could watch the door. He put the suitcase on another chair,

where it was within easy reach. Containing, as it did, a collection of chemical formulas, mostly pertaining to

gases, the bag was of importance to Jerry, especially as the formulas represented his own research of more

PEOPLE were coming into the restaurant, but Ardlan was not among them. Jerry wondered if he really had

remembered the telegram correctly. He pulled it from his pocket, and found that he was right. It said to come

to Washington on the express that arrived at six thirtyfive, and to meet Ardlan at the World Wide Cafe.

So Jerry put the telegram away and studied the menu, deciding to get a head start on his dinner before the

Men were seating themselves at the next table, and Jerry could overhear their conversation. It wasn't in

English, but Jerry had traveled around enough to know smatterings of other languages to the point of

This happened to be one that he couldn't class, though it had snatches of familiarity. (Note: Unknown to Jerry

Croft at this time, the language being spoken in the cafe is Esperanto. Jerry will learn the meaning of this

restaurant conversation later in the story. Throughout the story; if the text itself does not make the meaning of

the Esperanto clear, when it is spoken, a footnote will give the translation to the reader. For further

information about Esperanto, please turn to the end of this story.) At least, the men spoke plainly, so that their

Jerry looked toward the speakers and stared. One of the four was the man who had been on the train, there

was no mistake about it. Viewing the fellow in profile, Jerry saw the big forehead and its bulge; as for the

The others were speaking, and Jerry couldn't catch the odd words in the babble. Fortunately, at that moment a

waiter approached their table. They silenced, without noticing Jerry, but even the sudden quiet was curious.

They weren't worried about the waiter hearing them; they wanted to hear what he had to say, and it was in

There were nods from the rest. With wary looks, they began to point out items on the menu, that the waiter

jotted down while he nodded. By then, Jerry was behaving warily, too, but from the corner of his eye he was

They looked foreign, but of what nationalities, Jerry could not guess, except that they varied. The waiter,

obviously a member of their group, looked more American than the rest, but his inset face, tawny in shade,

Sliding his hand in his coat pocket, Jerry found a little notebook and rested it on his knee. He had a stubby

pencil handy, too, and he decided to jot down what he heard next, particularly if the bulgebrowed man

The fellow was the one who did speak, just after the waiter had finished taking the orders. He motioned to the

Pocketing the order list, he became a typical waiter as he strolled away, and Jerry, writing the words as well

as he could remember them, was definitely sure of one: florbrasiketo. He regarded it as the most important

Apparently, by mutual consent, the four men were saying little; when they did, they spoke more rapidly and

kept their voices lowered; so that neither Jerry, nor any others close by, could overhear them, but their tones

A different waiter took Jerry's order, and while he ate, Jerry kept watching for the professor and speculating

about the tribe at the neighboring table. It might be just a coincidence that the bulgybrowed man had come

to the World Wide Cafe, and not a remarkable one at that, since the name of the place indicated that it was

Nevertheless, Jerry didn't like it, particularly when Professor Ardlan did not appear.

ARDLAN was somewhere in Washington; he had come to the capital to sell the government a wonderful idea

that he considered to be of military value, and the fact that Ardlan was staying in Washington indicated that

He had left Jerry with enough work to keep him busy indefinitely, instructing him to stay at it until further

Jerry had enough money with him to stay at a hotel, but that wouldn't help to find Ardlan. The professor was

absentminded at times, but there were others with him, and one in particular, Trennick, wouldn't let him

forget an important appointment. In fact, Trennick had probably sent the telegram for the professor, unless

The thing rang home while Jerry was looking at the man with the bulgy forehead. Could it be that the

telegram itself was a hoax? That someone in the queerlooking outfit had sent it, signing the professor's

name, and that the man with the big brow had been assigned to pick up Jerry's trail along the way?

Professor Ardlan often had ideas that people were following him, but could never furnish proof. In Jerry's

case, it was different. He couldn't say that the man had followed him to the cafe, but the fellow had come to

the same place, which amounted to the same thing, and perhaps more. It might even mean that he had known

There was a way to find out. Jerry's waiter had left the check, and it came to an even sum, allowing for the

tip. His hat and suitcase close at hand, Jerry reached for them under cover of the table.

He noted that the man with the bulgy head was busy over a plate of broccoli and figured it a time for

opportune departure. Before any of them realized it, Jerry had his hat and bag and was on his way.

There was a cab outside, and stepping right into it, Jerry looked back. He saw the waiter the one who talked

the odd language gesticulating to the men at the table, and they were coming to their feet, not bothering

about their checks, which the waiter, as one of their crowd, could pay for them.

Men didn't bolt from the middle of a meal unless there was a fire, or they had chosen to go after someone

In this case, the early bird was Jerry. He didn't intend to waste his advantage hunting for worms. He was in

"Next corner," responded Jerry. "Turn left, then I'll give you the address. I'm in a hurry."

Hurry or no hurry, the cab was just turning the corner when Jerry saw the quartet tear from the World Wide

Cafe and pile into a speedylooking sedan that had pulled up to receive them. Then Jerry's cab was around

"Then turn off wherever you can, but keep going. Look into the mirror; you'll see that somebody is after us."

The driver looked into the mirror and caught a glimpse of Jerry, as well as the car behind. Jerry struck him as

He took the straightaway at his fastest clip, swerved finally into a drive that followed the river's curve. The

other car did the same, and when Jerry looked back, he not only saw that it had gained, but had the sinking

Grimly, Jerry Croft set himself to meet the unknown future, confident that when the critical moment arrived,

THE cab took a sudden swerve, ripped its way between two Japanese cherry trees, hooked another, skewed

about, and wound up within a biscuit's toss of the river bank. Two doors shot open at once one on the left

front, the other at the right rear. The front door emitted the cabby, the rear one disgorged Jerry and his bag.

Staying on the road and stopping farther on, the pursuing sedan let loose its fourman quota. They saw Jerry

Jerry tried to chuck the suitcase into the Potomac River, but it was heavier than a biscuit and wouldn't carry

that far. He went after it, trying to kick it ahead of him. Failing he ducked around the front of the cab, hoping

that he could scout up the cabby and enlist his aid in going after the four men, if they obtained the suitcase.

They didn't bother about the bag. They wanted to get Jerry, instead. Two rounded the front of the cab, as he

had; the other pair cut in from the rear. Jerry saw the second car of the pursuit line, as it nosed in through the

cherrytree wreckage that the cab had caused. He'd only be cut off if he kept in that direction. Desperately,

Four men were upon him, a pair from each direction, and they were swinging things that gleamed: guns. His

hands up to ward off the blows, Jerry felt a surge of overwhelming blackness that struck like an avalanche.

He went down beneath it, sensing blows that he thought must come from slugging guns, only to realize that

Feet that went jouncing away in one direction, toward the river, as if one pair of attackers had driven back the

Staring from proppedup elbows, with his hands clapped to his head, Jerry thought that the four were

fighting among themselves which seemed incredible for the moment, but faded into simplicity at what he

They weren't fighting each other; they were battling blackness! Slugging wildly, guns were meeting others

It was a shadowy struggle with an invisible foe, so far as Jerry could view it, until the swirl of battle carried

There, with invisibility denied him, the fighter who had taken on the odds declared himself, with a laugh that

carried weirdly out across the river. It was a laugh of challenge, defiant in its mockery, threatening ill to the

opposition, regardless of their number. Amid the swirl, Jerry saw the figure of the lone, intrepid fighter.

Cloaked in black, a slouch hat upon his head, this terror to men of evil was sledging with a pair of automatics

that were as large as bludgeons. His gloved fists were using their weapons with such advantage, that he was

Jerry had never seen The Shadow; in fact, did not identify him at the moment. He saw a being in black, a

superhuman warrior, which was enough. He knew that The Shadow must have come from the second car;

Those men who babbled in a strange tongue were not profiting by The Shadow's arrival, and recognizing it,

Scattering like debris tossed by a tornado, they came about to blaze with their guns; they were in darkness,

and they were shooting back at the light that fronted the cab, hoping that wild aim would clip their foe.

But The Shadow was no longer a target; he, too, had gone into darkness. Only Jerry glimpsed the long plunge

FROM the water's edge, guns spoke. Their stabs told that The Shadow was not submerged; he was using the

low entrenchments afforded by the bank to knife back his replies to futile shots.

Yelps from near the taxicab indicated that The Shadow was scoring hits. Jerry heard one man stagger past

him, while the others ran. Rising, he tried to grab at least one fugitive, but all were past him, heading toward

Again, The Shadow's laugh; this time, its trailing tone carried a warning that Jerry didn't understand at first.

Another man was joining Jerry the cabby, who had regained his nerve, now that he was with the hounds

Somewhere behind them was The Shadow; confident of his support, Jerry thought that this pursuit was what

He found out differently when he and the cabby overtook the four men. Two were helping the staggering

fellow, while the third, who happened to be the bulgeheaded man, was carrying one arm rather limp, as

though from a deep flesh wound. It was he who turned to brandish a revolver at Jerry and the cabby at sight

Instantly, The Shadow's gun spoke anew from somewhere in the background. Then did Jerry understand the

folly of his own pursuit; the reason for The Shadow's warning. Not only Jerry, but the cabby, too, had

blocked off The Shadow's fire. Otherwise, the cloaked marksman would have halted the four fugitives, to the

Two of the men, unscathed, had put their stumbling companion into the car; the driver was starting it away

when Jerry saw the fourth fugitive, the man with the big forehead, spring into the front seat.

The Shadow tongued a few shots after them, and they jabbed back, but his purpose was merely to draw their

fire away from Jerry and the cabby, who were much closer to danger than The Shadow if he could be

Intervening trees helped render futile the last exchange of shots, but Jerry was alarmed by the sudden way

The Shadow's gunfire halted until he heard sirens wail and saw motorcycles whirl in from a broad, curving

Police had heard the gunfire, and by allowing the escaping opposition the privilege of the last few wasted

The cabby was hurrying back to the cab, and Jerry decided to do the same, on the chance of meeting the

mysterious fighter who had so ably rescued him. Finding The Shadow in the dark would be impossible, but

On the way to the cab, however, Jerry remembered the suitcase. He knew that the men who talked the strange

tongue hadn't taken it, so it logically belonged at the place where Jerry had last kicked it.

Finding the place was the trouble. The cabby had turned off the headlights, in order not to attract any police

who might come trailing after the first squad, so Jerry decided to ask him to put them on again. He reached

The suitcase was in the cab, and Jerry eagerly opened it, while the cab was backing around and nosing for the

opening between the trees. The lights were on again, and Jerry saw that The Shadow's car was gone.

As swiftly as he had arrived, the mysterious fighter had departed, hoping, perhaps, that he could pick up the

racing motorcycles, to find the fugitive car that was trying to outrun the police.

Jerry's formulas were just as he had packed them. The driver was taking to the curved drive, and Jerry saw

that it skirted a roundish landlocked reservoir the Tidal Basin, jutting in from the Potomac.

"Guess they kind of had us worried," piped the cabby, from the front seat. "You're a cool guy, though. I could

"Yeah. Or, maybe" the cabby paused, to peek at Jerry in the mirror "or maybe you were still kind of

"I guess I was," acknowledged Jerry. "I don't exactly remember giving you the suitcase."

THE cab was swinging into a meshwork of streets where laidout squares, simple in themselves, were

rendered mazelike by the angular crossings of intervening avenues. The cabby knew his way around, for he

performed twists that kept carrying the cab along one general direction, but why he was heading that way,

Jerry was about to put a question, when a sudden idea struck him. Instead of asking the cabby where they

"To the address you gave me," returned the cabby. "That is, if you remember telling it to me, the same time

"I remember that part," assured Jerry. "I just wanted to make sure you got it straight."

For all that Jerry knew, their destination might be in Timbuktu, not Washington, but at least he understood

It must have been the cloaked rescuer who had handed the cabby the bag and given him the address in a tone

which could have been Jerry's. Up to that time, any tone could have been Jerry's, so far as the cabby was

concerned, for their only previous conversation had been an excited one outside the World Wide Cafe.

Maybe the cabby was catching the discrepancy, now that Jerry was talking normally. Maybe not, but in either

case it didn't matter. They were bound somewhere, at The Shadow's order, and Jerry Croft was willing to

The cab swung into one of Washington's many secluded streets, where old houses stood half hidden behind

rows of shade trees. The cabby poked along looking for the number that he wanted. Finally halting in front of

He paid off the cab driver; went to the door of the forbidding house, wondering suddenly whether he might

be walking into another trap. The cab was lingering, as if through its driver's curiosity, and Jerry was

remembering that he had only the cabby's sayso regarding the address given by the man he thought was his

Maybe the fellow was in the game and had taken Jerry to the river side so the pursuers could box him. With

The Shadow gone, the cabby could have faked his yarn, and this very house might be the headquarters of the

If so, the cabby would give the alarm if Jerry welshed at entering the house. If not, he'd at least wonder. The

door latch was clicking, and Jerry faced the barrier with tightened fist, hoping that he'd meet The Shadow, or

He met neither. Half stepping across the threshold, Jerry continued on a pace, staring in real surprise. His

hand came up, its fist unclenched, to receive the clasp of a shaggyhaired man who greeted him with a

Jerry Croft had kept his appointment in Washington or, rather, The Shadow had arranged that he should

keep it. The man who was greeting Jerry was none other than his singular employer, Professor Urlich Ardlan!

INSTEAD of clearing the mystery, the meeting with Ardlan only deepened it for Jerry, though he was

Once the door was closed, Ardlan's laugh took on a triumphant tone, for the benefit of two men standing by.

Jerry recognized one, a pale, dryfaced man with deep eyes and long chin, who happened to be Trennick,

Ardlan's trusted servant. The other was heavier set, darkcomplexioned, and mustached. He gave Jerry a

Professor Ardlan introduced the darkish man as Vic Marquette, from the Federal Bureau of Investigation.

"You see?" queried Ardlan, turning from Trennick to Marquette, "I did send the telegram, as I thought,

Marquette nodded, while Trennick gave a worried stare. It was Marquette who spoke to Jerry.

The query was blunt, and it seemed a criticism of Professor Ardlan. Marquette seemed to want a direct

Satisfied with the reply, Marquette shrugged and turned away from Jerry, who decided, therewith, to

"It's still too bad you named this address in a telegram," said Marquette to the professor. "Nobody is supposed

"Exactly what I told Professor Ardlan," put in Trennick, "and I was sure, sir" this was to the professor

Another shrug from Marquette indicated that he considered the matter closed. But it wasn't so to Jerry. He

was quite convinced that Ardlan hadn't sent the telegram, not only because of the professor's penchant toward

absentmindedness, but because the telegram in Jerry's own pocket did not match the one described. It had

There was only one answer: someone else had probably wired Jerry; perhaps the bulgebrowed man, which

would mean that he or some of his associates spoke English, as well as their peculiar, unidentified language.

They had brought Jerry to the World Wide Cafe to waylay him before he reached this address.

Jerry pondered his own mental question and came to the conclusion that The Shadow was someone who had

been watching the group of curious linguists, and seeing them go after Jerry, had taken a hand to stop them.

But only The Shadow could have given the cabby this address, which meant that The Shadow knew much

Those were things that Jerry ought to have told Vic Marquette. There was a reason why he didn't. It was

"I'M glad you're here, Croft," said the Fed. "According to Professor Ardlan, you're the one man he trusts "

"I trust Trennick, too," insisted Ardlan, clapping his hand on the servant's shoulder. "But each man to his

duty. Croft is my assistant in scientific matters, while Trennick attends to my personal affairs."

"Getting to the point, Croft," continued Marquette, "I'm here to make sure that the professor's invention is

quite safe. He insists that it is, because Trennick is on watch. But I have no proof" his tone was emphatic

"I've shown you the room!" boomed Ardlan. "Down in the cellar, where I keep my Neutralizer "

"But how do I know what's in the place?" demanded Marquette. "Maybe you're keeping a hippopotamus

downstairs, or maybe nothing at all! I've asked Trennick; he doesn't know. He's seen the outside of your

"The professor does have an apparatus that he terms the Neutralizer," he declared. "I have seen it, Mr.

Turning to the professor, Jerry suggested that he show the Neutralizer to Marquette. At first, Ardlan was loath

to agree, but at last he gave the nod and they went down to the cellar, with Trennick following. They came to

a steel door which had a combination lock, like a safe. Ardlan crowded himself in front of the combination,

so that not even Jerry could watch him operate it. When the professor opened the door, Jerry noted that the

Marquette started to enter, but Ardlan held him back. He insisted that neither Vic nor Trennick step across the

In the strong room, resting on a table, was the strangest contrivance that it had ever been Marquette's lot to

see. Trennick, too, stared openmouthed, for he had never been privileged to look at the Neutralizer before.

Its center was a squarish box, not unlike that of a radio cabinet, except that it had a greater variety of knobs

and dials, at least two dozen of them. The front was about four feet square, though the cabinet was less than

that in depth. A row of lights, of different colors, ran along the top of the cabinet, and there were two

Even more curious were the devices that topped the cabinet. They looked like small megaphones turned

upside down, and they were drilled with holes. Each was capped with a glass bell, and in each crystal dome

was a tiny fan, aimed downward. A chromiumplated bar ran along the tops of these bells, serving as a

The cabinet itself was flanked with cylindrical tanks about the size and appearance of small fire

extinguishers, except that they were made of glass. Each contained a liquid, and the colors varied, from

jetblack, through green and amber, to a smokywhite. These upright tanks, which formed two columns of

PRESSING a switch, Professor Ardlan caused the lights to glow; those along the top flickered, but the

diamond groups remained constant. Another click, and the fans began to whir in the glass bells, producing a

sucking sound from within the inverted funnels. Ardlan tapped the oddshaped stacks that topped the cabinet.

"The Identifiers," he explained. "They sort gases and classify them, automatically. The lights will then

Marquette rubbed his chin; Ardlan noted it. He stepped toward an oldfashioned gas jet in the corner of the

"Not necessary," he said. "It would be too much trouble as a mere demonstration. Just step over, Jerry, and

breathe close to the Identifiers. I am not sure which is the proper one, but we shall soon see.

Jerry complied. He was breathing against the third funnel in the row of eight, when the flicker of the lights

He manipulated a switch at the left, until only yellow and blue shone from the diamond at that side. Going to

the right, he repeated the process. When he turned a central knob, two vents popped open, one in the middle

Jerry kept on breathing as the professor gestured, but it was no use. Though Ardlan had stepped away from

the cabinet, the vents closed suddenly and the diamonds glowed anew with all four colors, while the lights at

The professor was pointing to one of the tanks at the side of the cabinet; Marquette observed that its liquid

"Enough, Jerry," said Ardlan. "Don't get yourself out of breath." He turned to the door. "Mr. Marquette, you

have seen what my Neutralizer does. It sucks in gases, identifies them, and provides a vapor that neutralizes

phosgene. I have experimented with all of them, along with chlorine and mustard gases. I regard them as

He was coming to the door, bringing Jerry along. Marquette, still looking at the tanks in the corner, gave a

"No," returned Ardlan. "I am more concerned about my Neutralizer. Look!" He stepped back to the cabinet,

where he had already turned off the switches, and pressed two catches. As he tilted the device forward, the

top lifted and showed the interior an array of pipes, fans, wires, and coils, with drycell batteries perched

"Entirely selfcontained," declared Ardlan. "And all the plans for it" he was tilting the cabinet back with

one hand, while he tapped his forehead with the other "are locked right here. It would take me hours,

perhaps days, to go over the mechanism, should anyone meddle with it. The misplacing of even a single wire

would put it entirely out of order. That is why I allow no one to touch the Neutralizer."

MARQUETTE started upstairs with Jerry, while Trennick waited for Ardlan to lock the door. Drawing Jerry

"No,", replied Jerry. "My work is research. I dope out chemical formulas for neutralizing compounds."

"Tell me," asked Vic, narrowly. "Had he been working on perpetual motion before he started this thing?"

The inference was plain. Marquette thought that the professor was a crackpot, despite the recent

demonstration, which in itself meant nothing, because the machine could have been rigged to produce the

Behind the thought was Vic's mistrust of the professor, which was reasonable, considering Ardlan's eccentric

Smiling at Marquette's doubts, Jerry insisted that he, at least, had faith in Professor Ardlan; but, therewith, he

He doubted that Marquette would have any regard for the opinion of a man who talked of enemies who spoke

an unknown tongue, and a friend in black who had fought them off and then vanished like a ghost. He didn't

suppose that Marquette could believe in the existence of such a person as The Shadow.

That was Jerry's mistake. Marquette did know about The Shadow. It was a mysterious tipoff from the being

in black that had brought Vic to Ardlan's. Had Jerry mentioned The Shadow, Marquette would not have

doubted his sanity. On the contrary, he would have placed more confidence in Ardlan's young assistant.

Marquette left soon after Ardlan came upstairs, and it wasn't long before the telephone bell rang. Ardlan

answered it, and Jerry heard him hold a blunt conversation. Returning, Ardlan announced to Jerry:

"The millionaire manufacturer," nodded Jerry, "who wanted to finance your invention. Is he here in

"Yes," said Ardlan. "On a matter of some government contracts. He made me another offer, Jerry!" The

professor's voice became a confiding whisper. "Half a million dollars for my Neutralizer, as it stands!"

"Of course!" Ardlan leaned back and boomed a satisfied laugh. "My invention is for the benefit of all

mankind, not as a thing of profit for Bradwell. Here is news, Jerry" again it was a whisper. "The official test

Trennick was in the doorway. The dryfaced servant spoke remindingly to the professor.

"Anderton called me this afternoon, Trennick," he said. "Have you forgotten so soon? It is your memory that

Trennick retired, apologetically, closing the door as he went. Once in the hall, however, the servant no longer

looked forgetful. Instead, his usually dull face was shrewd, as he sneaked to the telephone and dialed a

When a voice answered, Trennick spoke words that Jerry would have appreciated had he been present to

"Li alvenis sendangere," undertoned Trennick, "sed il rakontis nulo. Diru al mi, cu il evitis vin?" ("He arrived

safely," undertoned Trennick, "but he said nothing. Tell me, did he avoid you?")

Trennick was using the same language as the men in the World Wide Cafe! He was being understood, for the

"Ci tio estas grava," declared Trennick. "Illi estas preta provi la aparato. Morgau nokte estos nia fina okazo

malebligi iln." ("This is important," declared Trennick. "They are ready to test the apparatus. Tomorrow night

Hanging up the receiver, Trennick took quick catfooted steps along the hallway when he heard the creak of

the parlor door. He was gone, into the kitchen, when Professor Ardlan and Jerry Croft appeared. They

stopped at a table in the hallway, where Jerry had left his bag. He opened it to give Ardlan the sheaf of

Another door was opening, but it did not creak. It was the front door, which the professor thought was

securely locked; it had been, until a few moments ago. Through the crack of the door, The Shadow saw

"Trennick is preparing you some supper," the professor told Jerry. "He is thoughtful and faithful. I shall take

these down to the laboratory, and return later. I feel quite safe, Jerry, now that you are here, along with

The front door closed; its lock turned noiselessly under the probe of a special key provided from the other

side. As far as The Shadow had seen and heard, all was well in the abode of Professor Ardlan.

How Trennick's unsuspected treachery was to change the situation, only the future could reveal unless The

LATE the following afternoon, Jerry Croft took a cab from near the professor's house and rode to an

apartment hotel nearer the center of Washington, keeping sharp outlook along the way. He felt it safe enough

to be at large, since nothing untoward had occurred since the adventure along the Potomac River.

It was better, too, that Jerry should make this trip than the professor which was the only other alternative.

Better, too, because Ardlan wasn't in the right mood to call on Congressman Howard Anderton, who was the

From things that Ardlan had told Jerry in the morning, Anderton must have found the old professor to be

quite a Tartar; in fact, Jerry wondered how they had gotten together at all. With the test of the Neutralizer

finally decided upon, it would not do to let Ardlan ruin his chance on the last day, so Jerry had gladly

Congressman Anderton had a little office in his hotel suite, where he received people after hours. It was not

much more than a reception room, where a young man, apparently Anderton's secretary, was on duty. Jerry

Anderton was as big a man as Ardlan, but bald, instead of shaggyhaired. His face, though stern, was

"Glad you came, young man," announced Anderton. "I've had a deuce of a time with that professor friend of

yours. Wish he wasn't from my congressional district. Yes, I actually do. Sometimes, I almost think he's

Jerry didn't ask about the man in question. He merely wanted to know about the test.

"We'll hold it at the proving grounds," declared Anderton. "Ardlan says the apparatus is effective within a

radius of thirty feet, outdoors as well as indoors, so we'll have the test outdoors, to let people look on. We're

going to use goats. Souse them good with some poison gas and let the professor show that he can save them."

There was a chuckle from the door. Jerry looked to see a tall, rugged man whose square face wore a smile,

though it wasn't exactly a pleasant one. Somehow, those features looked familiar, with the grizzled hair above

Jerry remembered why, when Anderton introduced the visitor as Rufus Bradwell. Once Jerry had seen

"So you're going to let the witch doctor have a try," chuckled Bradwell, referring to Ardlan. "He'll have to use

plenty of hocuspocus along with that mechanized brainstorm of his, or it will be tough on the goats. When is

"Tomorrow afternoon. We aren't announcing it publicly, though, because Ardlan preferred otherwise."

"I am afraid that he has." Anderton turned to Jerry. "Frankly, Croft, the professor has been a nuisance. For

example, he insisted that Congress appropriate a million dollars before it was even tested, as a guarantee that

"He feels that it's a human benefit," said Jerry, "but he also told me that he was willing to take your word that

"And would donate it to all the world," added Anderton, "so that peoples of all nations could be protected

"A million dollars," Bradwell ridiculed. "Why, I wouldn't give another five thousand for the other half share!"

AT Jerry's surprise, Bradwell explained. He said that he had loaned Ardlan five thousand dollars to start work

on the Neutralizer, two years ago. He had letters to prove it, containing the statement that he, Bradwell, was

Of course, if Ardlan chose to give the invention away, that would leave him owing Bradwell five thousand

"We agreed to develop the device," stated Bradwell. "If Ardlan doesn't, I can. I have some of his earlier plans,

and basically, the thing has merit. But I think that Ardlan has gone off the track, as he always does. So I've

put other men to work along the same plan. Perhaps they will succeed if Ardlan does not."

Jerry couldn't readily believe that Ardlan would have given anyone the rough plans of his earlier work; but he

knew that there were things the professor had never told him. Moreover, Bradwell's statement, considered

logically, fitted with something that Ardlan had said the night before; something in keeping with the

The offer of half a million dollars hadn't sounded plausible, but now Jerry could reconcile it. If Bradwell

already held a half interest, and Ardlan figured the government would spend a million dollars, that meant that

Probably Bradwell had merely requested that Ardlan let him handle the whole thing, which would lead

Ardlan, in his nonetoorational way, to consider that he had received an offer of half a million dollars.

"All I ask is this," said Congressman Anderton, wearily. "You produce the professor at two o'clock tomorrow

afternoon, Croft, and have him bring his invention. I'll bring the goats, though he ought to be able to produce

them, too. He's got my goat, and Bradwell's, and a dozen other people's, I suppose!"

Smiling at Anderton's jest, Jerry was still trying to figure out Bradwell. Obviously, the millionaire was trying

to disassociate himself from Ardlan, at the same time claiming that the professor owed him something. Jerry

was beginning to wonder just how much the invention, if really practical, might be worth to a farseeing

"I can understand Ardlan's fear of enemies," said the congressman. "If news of his invention spread too far, it

"There are certain governments that would prefer to keep poison gases as an effective offensive weapon, and

they wouldn't care to have the Neutralizer get into circulation as a defensive measure. We know for a

certainty that such nations have agents operating in this country. They may be the enemies that Ardlan talks

Jerry doubted that Ardlan was worried about foreign spies. The idea was too rational for the professor. But

Jerry's own experience with men who certainly were not Americans gave potency to Anderton's statement.

About to leave, Jerry paused as a girl came through the door. She was very pretty, and trimly dressed, and

Anderton introduced her as his daughter, Ruth. She was about nineteen, and worthy of the admiration that she

He appreciated her sparkling blue eyes, brown hair, and saucy lips, but classed her as a trifle snippy. He could

tell that she was spoiled, too, from the proud way in which Anderton received her.

As for Ruth, she perched against the edge of the desk and looked directly at Jerry, as though to say that she

The glance that she gave toward Bradwell was her way of classing him as a dodo. Maybe she thought that

SHAKING hands with Jerry, Anderton turned to his daughter to say, almost apologetically:

"You do!" Ruth finished the exclamation with a pout, then turned to Bradwell. "But I'd been counting on you,

Mr. Bradwell, to take me downtown in your car to the Club Fiesta. You said you would, you know. You have

"I know," said Bradwell, gravely. "My car is waiting, Ruth, with Winstle at the wheel. He is a fine driver "

"And you expect me to ride alone?" Ruth interrupted, in horror. "Why... why" she stared at her father, then

She might just as well have shouted what she wanted, as far as Jerry was concerned, and Bradwell, for that

matter; though Anderton, the indulgent father, was quite deaf to such wiles. Jerry saw Bradwell smile.

"You should have let me finish," admonished Bradwell. "I was about to say that I was providing you with an

escort, too. Your father's friend, Mr. Croft, will be very glad to accompany you to the Club Fiesta in my car."

Slipping from her angled position against the desk, Ruth took Jerry's arm and waved a goodby to her father,

who was nodding that it was quite all right. Bradwell gave Anderton a reassuring glance, and undertoned:

Bradwell did exactly that, but when he came upstairs again, he stopped in the reception room. He had noted

that the secretary was gone, and Bradwell wanted to use the telephone. Getting the number he wanted, he

"It worked... Yes, just the way I wanted it... No, there's plenty of time. Winstle is stopping for gas just around

the corner. Oil, too. He can stall five minutes, maybe longer. The girl won't give Croft a chance to argue "

"Yes. Before they get to the Club Fiesta. We've got to play it safe... Croft wants to get back to the professor's.

He'll shake the girl by that time... The rest are with you?... Good! Get started."

While he talked, Bradwell was watching Anderton's door. On that account, he couldn't see the outer door of

the apartment itself. It had opened and a man was standing on the threshold; he preferred to hold his steady

pose, rather than ease the door shut. It was perfectly safe, since Bradwell was looking the other way.

Had Bradwell turned, which he didn't, he would have recognized the arrival as Lamont Cranston, a wealthy

Tall, with a masklike expression on his hawkish countenance, Cranston watched impassively, hearing every

word of Bradwell's conversation. Even its abrupt ending did not perturb the intruder, for he, like Bradwell,

heard the creak from beyond Anderton's door and noticed that the knob was turning.

Away from the phone, Bradwell fairly bowled into Anderton as the latter was stepping from the study. In so

doing, Bradwell created the impression that he had hurried back without stopping on the way.

It was during that encounter that Cranston closed the outer door. Disentangled from Bradwell, and accepting

the grizzled man's apology, the congressman looked across the reception room, then glanced at his watch.

"I rather expected Cranston," he told Bradwell. "I guess I was mistaken. He always keeps his appointments

punctually. He must have said that he was coming tomorrow, not today. You've met Cranston, of course. A

More remarkable than either Anderton or Bradwell supposed. Lamont Cranston, the hawkish gentleman who

JERRY CROFT wasn't allergic to women. He was simply choosy, and within reasonable lines. He liked them

closer to his own age than nineteen, for Jerry was twentyfive. Moreover, he considered brains at least as

valuable as beauty. He felt that Ruth Anderton was as short on one as she was long on the other.

Winstle's delay at the gasoline station proved a nuisance, and so did Ruth. Jerry couldn't very well hurry

Bradwell's chauffeur, and the girl dodged his suggestions to that effect. She said that there wasn't any hurry to

get to the Club Fiesta. Jerry would like the crowd, of course, because Ruth did, but she rather preferred a

It was simply a case of getting properly introduced, though Jerry doubted that Ruth's definition of the term

Her questions were definitely to be approved; she wanted to know what Jerry did, where he'd been, and other

But the way she snuggled closer and kept lowering her tone, so that Winstle wouldn't overhear, was an

indication that she wanted to tow Jerry in as a new trophy, to impress her friends with her ability at using

Jerry didn't care to be a souvenir. If someone was to take someone else somewhere, he preferred to be the

taker. Maybe that would have suited Ruth even better, but Jerry hadn't come to Washington to cut a figure

He was thinking of humanity at large, and specifically concerned with Professor Ardlan. Tomorrow, his mind

Ruth could have her friends at the Club Fiesta, and to humor her Jerry was willing to let her think that he was

anxious to meet them. She'd get her surprise when the limousine arrived there; maybe sooner, if

circumstances so ordained. Telling people off was one of Jerry's habits, when they provoked him too much.

The limousine slowed for a traffic light that happened to be green, though it turned red very shortly. Jerry

observed Winstle's lapse in not going through, and wondered about it. He didn't puzzle long.

Another car wheeled up beside the big one. A couple of men jumped out and grabbed the limousine door.

Jerry started to open the door on the right, to find that a fourth man had pushed up from the sidewalk. The

fellow was masked, but he didn't show a gun. He was reaching for one, as he growled:

Putting his foot right in the middle of the man's chest, Jerry drove him so far across the sidewalk that the

fellow seemed to jar the bricks of the wall he bumped against. He sat down, but he had his gun in hand, so

Jerry figured the other direction was better. He turned, to see the first pair of thugs gripping Ruth and stifling

She was yanking at their masks, and they were too busy handling her to pull their guns. Up front, Winstle

Lunging shoulder first, Jerry bowled Ruth right out of the car and sent the two masked men sprawling ahead

of her. They took wide dives, and at that moment Jerry saw a cab, its door open. Its driver had seen what was

Remembering the cooperating cabby of the night before, Jerry picked up Ruth and thrust the gasping girl

into the yawning door. As he jumped in, the cabby slammed the door and was away, just as guns began to

Jerry managed to look back, despite Ruth's stranglehold. The thing he saw amazed him. Those guns had

Four thugs were going into action against a fighter whose ability was sufficient to make Jerry's flight with

FROM a rather amateurish preliminary, the thing had become a professional bout, though Jerry Croft wasn't

on hand to witness the transformation. One thug had luckily spotted The Shadow springing from an arriving

car and had yelled the word to the others, emphasizing it with his gun, before The Shadow's taunting laugh

Now, with mockery as a challenge, The Shadow was blazing back, scattering his foemen as they fired their

hasty shots. Here, under the changing glow of the traffic light, he had an opportunity to deal with enemies

Only one man had gotten back into the other car. If Winstle had held his ground, the others would have been

trapped flatfooted. But Winstle stepped on the gas and sent Bradwell's limousine roaring through the traffic

The fact that it was red didn't bring a collision. All other cars in the vicinity had darted away. The thing that

counted was the fact that Winstle took three thugs along on his running boards two from the street, the

To witnesses, it appeared that Winstle didn't want such passengers, but The Shadow knew better, for Winstle

was Bradwell's chauffeur and this was Bradwell's game. Moreover, the speed that Winstle made with the big

car, his deft way of rounding the nearest corner, where a hotel offered cover, showed that he wanted to save

In his own car, a coupe, The Shadow was in pursuit, but he saw the futility of the chase. This was a great spot

for a getaway, thanks to the crisscross of avenues. Once clear, Winstle would simply let his passengers drop

What The Shadow wanted was a car that didn't know that it was being trailed. Doubling back on his course,

It was the car that had brought the thugs that Bradwell ordered. Its lone occupant, the driver, thought that

His mask pocketed, the fellow was acting as though his car was just another of the lot that had scattered

during the fray. He was driving timidly along an avenue, taking care not to violate traffic regulations, and The

There were other cars, quite a few of them, in the forming procession; which turned the pursuit into a

slowmotion chase. After several blocks, the car ahead turned into a numbered street, then into a lettered one,

The Shadow did the same, but in an inconspicuous fashion, while the one attendant on the lot was checking

The unmasked thug started through a little alley in back of the parking lot, and The Shadow followed. He saw

the man enter the rear door of a small office building, and waited until a light appeared on the second floor.

Taking advantage of the darkness, which had settled before The Shadow left Anderton's hotel, the cloaked

trailer entered the building and found a stairway. Getting into the office was easy. The man ahead had left the

The Shadow saw him plainly in the light of an inner office, part of a tworoom suite. From the outer

darkness, The Shadow reached the door and overheard the telephone conversation that the fellow was making

to someone, who could only be Bradwell. The unmasked thug had a roundish face, but he looked quite tough,

"Hello, chief... Yes, this is Hortland. Thought you'd be back home... Yes, we got Croft out of the way... No,

he wasn't hurt, and neither was the dame, but he won't get back to the prof's for an hour, anyway. He fell for

"We had trouble, though The Shadow... Yeah, he showed up and went after Winstle... Don't worry, the

boys will drop off at the right places... Winstle? He'll be a hero, like Croft. The whole thing is a setup, the

HORTLAND was in a jam and knew it, as he hung up the receiver. Chance blackness had entered the room

and encroached upon the desk, and the fellow was lucky enough to spot its silhouetted form just before it slid

away. It was rarely that The Shadow approached too close, but on this occasion he did.

Perhaps because it didn't seem to matter at the moment. Hortland had told Bradwell that he could call the

right guys in a pinch, and "right guys" were usually made to order for The Shadow. If it meant bringing

Back in darkness, The Shadow waited. He saw doubt reflected upon Hortland's face. The fellow wasn't quite

sure that he had spotted indications of The Shadow. Nevertheless, he picked up the telephone and dialed it.

The undertone that Hortland used was quite a contrast to his speech with Bradwell. Watching for the

silhouette, Hortland was sure that The Shadow, if present, couldn't overhear. Still, Hortland was playing the

thing doubly safe. He didn't know that The Shadow, by choosing a new angle, was hovering almost in back of

Hortland was using the same language that Jerry had heard at the World Wide Cafe!

That part was obvious; Hortland was announcing himself to someone named Malga. But the rest of his

me... Send someone to aid me... Hurry... What?... They followed him!... They await the bell... I shall ring it,

HORTLAND was lowering the receiver with one hand, and The Shadow couldn't have seen the movement of

Beneath the desk, Hortland's thumb was pressing a button which produced no sound within the office. It was

Yet The Shadow wheeled as if actuated by the signal that he could neither see nor hear. Driving through the

darkness of the other office, he was at the hallway door as it bashed inward to admit a surge of men, who

As he went, The Shadow uncloaked a second gun, a mate to the one which he had used to cover Hortland. He

Hortland heard the impacts as The Shadow's automatics cracked revolvers from the hands that gripped them

Twitchylipped, the roundfaced man came full about, his hand fumbling his own gun as he pulled it from

his pocket. For Hortland recognized the mistake by which he had himself warned The Shadow, and thereby

The Shadow understood the language that Hortland had used across the telephone. In repeating aloud the

statements of Malga, the man at the other end, Hortland had given The Shadow a cue to the presence of the

HARD and swift were The Shadow's blows, yet with those strokes his own impetus seemed to fail. The very

men who were half staggered by his thrust were carrying him back into the darkened room, spinning the

Others were shoving in behind them, and to all, it seemed that they had met The Shadow's drive and stopped

Then, they felt The Shadow whirl away and knew that he had tricked them. Bringing them clear into the

room, some with gun hands numbed, others with aching skulls from which The Shadow's blows had glanced,

From various spots, the invaders turned to aim at the door; but, though there were four of them, not one was

The rule didn't apply to Hortland. He had a grip on his gun and was aiming it toward the upright oblong of

light that represented the outer doorway. As a sweep of blackness chopped across that space, Hortland jabbed

shots in quick succession. Above the barks of the revolver came an evasive laugh that might have come from

The Shadow hadn't made off through the exit, to pick up Hortland's bullets on the way. The thing that had

sliced into the doorway was the door itself, slammed by The Shadow. He preferred the darkness of the outer

He was still in the room with the blundering invaders, and Hortland was among them. They had planned a

As Hortland sprang back into the inner office and frantically yanked the cord of the desk lamp to put himself

in darkness, he heard shouts from the outer room. Shouts so loud, that they drowned his own as he tried to

"Restu proksimi de la fenestroj! Ili estas pli sendangere!" ("Remain near the windows! It is safer!")

Those were words The Shadow understood, though only Hortland knew it. Things happened very rapidly, to

the surprise of the recuperating invaders. Wheeled full about, The Shadow hurled himself suddenly upon

them at the other side of the room, where they were coming up from hands and knees beside two windows

They tried to spread, and stumbled across tables and chairs that they couldn't see, losing guns as they went.

But they were clever enough to turn their blunders into good account. They began to throw the furniture that

blocked them, and in that desperate effort, they bothered The Shadow more than they could have with guns.

Chairs and tables were big missiles. The Shadow could not escape them by dropping close to the floor, for

they bounded all about him. He saw the shapes against the slight light from the window, and maneuvered

Nor did the chucking process give away the positions of the foemen, as gun stabs would have. Inadvertently,

these enemies were using the best possible system. None of them stayed long in one spot, as they would have

had they paused to fire. Needing more furniture, they went after it by the simple process of darting about,

That made them impossible targets, considering that The Shadow, himself, was also on the move, avoiding

There were more shouts in the language they all knew, each man telling the rest to keep to the task. The

missiles were increasing in size as they lessened in number, for the furniture was breaking apart against the

walls. A table top smashed a window, carrying away all the glass, and the clatter gave someone an idea.

"Mi iras al la tero!" called a voice. "Gi estas pli amike ol La Ombro!" ("I am going to the ground," called a

POUNCING upon the shouter, The Shadow caught him close by the windows and flung him back upon the

others, as they surged in the same direction. They were lashing about with heavy clubs legs from tables and

chairs which had a longer reach than The Shadow's guns. But they were after the windows, not The

The Shadow jabbed shots to stop them, but his gun hand was gripped by the man who had bounced back at

him from the human wave. The Shadow saw the fellow; he was the man with the bulgy forehead, who had

trailed Jerry Croft. Therefore, he could not be Malga, to whom Hortland had made the telephone call. The

The bulgy man was putting up a frantic fight, despite the fact that his left arm was bandaged. With others

plopping through the broken windows like parachute jumpers, he wanted to do the same, since it had been his

He slashed at The Shadow with a handy chair leg, wrenched free to the window sill, and toppled across.

From the outer door came a shaft of light. The Shadow had counted three men going through the window;

this fellow was the fourth. One other must have chosen the way through the hall, and the man was logically

Hortland. To The Shadow, he was more important than any of the rest, for Hortland had talked to both

Half through the doorway, Hortland saw the last of the rescue crew go rolling through the window. Still

gripping his gun, Hortland hoped that he would see The Shadow following them and get another chance at

Hortland found his chance, but not as he expected it. Blackness itself came swooping in upon him from an

Bodily, The Shadow bowled Hortland out into the hallway, shoving the fellow's revolver upward so that its

spouting shots were as harmless as those of a popgun. Hortland tried to slug instead, and each time, The

During that process, he was shoving Hortland along the hall in zigzag fashion, from wall to wall, each jounce

knocking more breath from the fellow. Hortland's collapse was imminent, as they reached the stairway. The

He knew that the thought of a fall wouldn't be pleasant to Hortland, otherwise the fellow would have chosen

"I'll... tell all I know! Let... let me live! I'll talk... I'll spill everything "

The Shadow was drawing him back from the stairs, when Hortland chanced to look below. A new glitter

came into his eyes; with it, he showed a burst of strength. Pulling away from The Shadow, Hortland gave a

A gun spurted; its bullet found Hortland's chest. But the gun was not The Shadow's. The shot was fired from

Malga, the man whose name Hortland had cried, was actually here in person, to learn how his crew had made

out. Having heard Hortland's promise of a full confession, Malga had decided to dispose of the man who

SPRINGING to the stair top, The Shadow saw Malga below. He wanted to get a good look at the man with

the illsounding name, for tonight was not the first time that The Shadow had heard of Malga. The fellow

was notorious as the hidden leader of an international group who worked for whatever country made the

When The Shadow took a look at men of Malga's ilk, it was always along the barrel of an automatic. On this

Below was a squatty man, standing with a smoking revolver; a vicious personality whose face looked like a

grinning skull, except that it was dark, not whitened. Though deep in their blackish sockets, Malga's eyes had

an evil glimmer; his lipless mouth was drawn in a death'shead grin. His gun, too, was lifted; he was looking

Muzzles spurted from both ends of the stairway, as The Shadow and Kurd Malga began their duel. It was the

sort that should have been settled instantly, according to whichever gained the splitsecond advantage, for

The Shadow was a sure shot, and Malga rated as the same. But this was a duel with an obstacle that rendered

The obstacle was Hortland, bouncing in his crazy, halting tumble down the stairs. Mortally wounded by

Malga's shot, the squealer was going through a convulsion that carried him from banister to wall and back

again, in crazy pitching fashion. The Shadow had to sidestep to avoid that flaying, downward perking form,

Again their guns blasted, as each made a shift. Malga's was first, because The Shadow knew his rival had

miscalculated the direction of Hortland's next pitch. Hardly had Malga changed his aim, before The Shadow

Though Hortland had gone in the direction The Shadow expected, a slump of the tumbling body twisted it

Crouched low, Malga jabbed a third shot upward, as Hortland took a long, unguided lurch for him. That shot

was very wide, for Malga made an ungainly shift to deliver it. The mistake saved him, for The Shadow's

blast, coming at the same moment, was placed where Malga should have been, but was not.

Darting away under cover of Hortland's final lurch, Malga reached the court, to hasten after the four men who

had plunged from the secondstory window. By the time The Shadow reached the ground floor and looked

As an urge to Malga's flight, came the blare of police whistles and the wail of approaching sirens. This battle,

Turning to the slumped form of Hortland, The Shadow lifted the man's head, which twisted crazily from a

neck disjointed by the plunge down the staircase. Dying, Hortland might have forgotten his willingness to

talk, so The Shadow reminded him emphatically, speaking in the language that Hortland had used earlier.

It was useless. Hortland's eyes were staring glassily from his flabby head. The man who knew too much had

died too soon. Kurd Malga had at least seen to that before dueling with The Shadow.

Letting Hortland's dead form slump to the floor, The Shadow faded into the outer darkness. Gliding swiftly

across the courtyard, he melted from the glaring flashlights of arriving police; who promptly stumbled upon

By then, The Shadow was gone into the night, bound to another destination, where he knew too well that

Through Hortland's death, The Shadow had lost his chance to link definitely those two; but as to the game at

The Shadow's destination was the forgotten house where Professor Urlich Ardlan lived, sole possessor of an

amazing, yet unproven invention that might be a boon to thousands of helpless persons throughout the world.

AT the very time when The Shadow was starting for Ardlan's, Jerry Croft was thinking in terms of the

professor, too. Jerry and Ruth were still riding in the cab which had so luckily plunged them out of danger,

The fellow was acting as if a batch of pursuing cars were close behind him, which didn't make sense to Jerry.

Looking through the rear window, Jerry saw no one in pursuit, and began to figure what the answer really

Smart of Bradwell, Jerry decided, to have this cab show up just at the right time. He couldn't have let Winstle

do a runaround all over Washington with the limousine, for that was something that could be traced back to

Ruth was clinging close to Jerry, bothering him every time he turned to look back through the rear window.

Her eyes had their saucy gleam, for she was enthusiastic, rather than frightened, over the adventure, and the

"How thrilling," she murmured, "the way you fought them, Jerry, and brought me away! I don't care if they

She spoke as if she believed it, but Jerry took it for flattery. There wasn't anything to worry about; no

pursuers were on the trail, and Ruth knew it, for she had looked through the rear window, too.

Jerry was tired of the hero stuff, and considered himself a dupe, instead. The animosity he felt toward

Bradwell, who had shoved him into this thing, was sufficient for Ruth to have a share.

If it hadn't been for the girl, Jerry would have stayed at the scene of battle. Instead, he had done just what

Bradwell figured: he had seen to Ruth's safety ahead of everything else. She wasn't responsible for that part

of it, but if she had minded her own business and gone to the Club Fiesta alone in Bradwell's car, instead of

The cab driver had finished his runaround and was bound toward the city limits, in a direction which Jerry

was sure must be the opposite from Ardlan's house. Pushing Ruth aside, Jerry told the fellow to stop being

foolish. When the cabby looked as though he didn't understand, Jerry put his hands through the front window

"Forget the gas and try the brake," urged Jerry. "If you don't, I'll see that you wreck this buggy, and it will

Unable to breathe, the cabby was already handling the wheel in wobbly fashion, and the prospect of a

headon smash with a car from the opposite direction made him agree with Jerry. He applied the brakes, and

Jerry relaxed pressure accordingly. The cab pulled over to the side of the avenue.

"Honest, I don't know who those guys were!" the cabby panted. "Someone, slipped me a tenspot and told

me I was to help a guy and a dame out of a jam. He told me where I was to be, and said to keep dodging, and

"No." The cabby shook his head. "He got into the cab where I was parked; then out again. All I heard was his

Jerry didn't inquire if the man had a bulgy forehead, since the cab driver hadn't seen his face. He did ask if the

man had talked with a foreign accent, or used any words in a language that couldn't be identified.

Shaking his head, the cabby said that the man had seemed like an American and had talked in very good

Giving the professor's address, Jerry told the cab driver to start there and make it fast. As they were turning

around in the avenue, he asked if the Club Fiesta would be out of the way, and the cabby said it wouldn't be.

Jerry told him to stop there first, and as a result, he listened to a barrage of stormy protests from Ruth all

Wherever Jerry was going, Ruth intended to go, too. If he thought it would mean more danger, and therefore

wouldn't take her, he could compromise by stopping off at the Club Fiesta, where she still wanted him to

meet her friends, more than before. Saying nothing until the cab stopped at the night club, where a doorman

stepped up to meet the cab, Jerry suggested that Ruth get out. She said that she wouldn't unless he did, first,

The gesture was her mistake. Jerry took Ruth's waist, hauled her across in front of him, and added a neat push

that sent her out into the arms of the astonished doorman. Before Ruth could find her feet, Jerry pulled the

ALREADY, Professor Ardlan was receiving visitors. They had arrived while The Shadow was busy with

battle and Jerry in the midst of undesired flight. There were three men in the party, and Ardlan had let

One, their spokesman, called himself Mr. Crumpf; he wore glasses that were connected to a gold chain

Crumpf's companions were about on a par with their spokesman. Both were drab and seriousfaced; they

"We cannot tolerate cruelty to animals," insisted Crumpf. "We are a committee opposed to such practices.

You must not harm those poor goats, Professor Ardlan. If you will not listen to our protests, we shall take

Crumpf's companions turned their headshakes to nods, at mention of legal measures.

"Who said I'm going to hurt the goats?" boomed Ardlan. "Nothing is going to happen to them!"

"Under the protection of my Neutralizer," interrupted the professor, "which makes harming them impossible."

"We must have proof," he finally said. "Proof that this device of yours really works. We've heard arguments

like this before, Professor Ardlan, and we always like to put a question of our own. Why, if all is safe, do not

humans accept such tests themselves, instead of placing the burden upon helpless, ignorant animals?"

"The goats aren't my idea!" stormed Ardlan. "I'd undergo the test myself, if I didn't have to demonstrate the

apparatus. It's just that people won't trust me, but goats will. Perhaps you gentlemen would be willing to

"Perhaps we would," rejoined Crumpf, "if we knew more about your Neutralizer, as you term it."

Ardlan told Trennick to show the visitors the way downstairs, but the professor did not immediately follow.

As he observed the man who alighted, Ardlan gave a beckon; leaving the door unlatched, he closed it and

went downstairs. Trennick and the visitors were standing near the door to the laboratory.

Working the combination in the usual fashion, Ardlan opened the door, but held back Crumpf and the latter's

companions. Gesturing for Trennick to enter, much to the servant's surprise, Ardlan followed him halfway

Smiling, Ardlan turned to the group at the door. They started to enter; again, he waved them back. "My

demonstrations," boomed Ardlan, "are always given under the proper auspices. I think it proper for everyone

to show credentials. Turn around, gentlemen, so that I may introduce you to Mr. Marquette, of the Federal

They turned, to see Marquette standing with a drawn gun, displaying a badge with his other hand. It was Vic

Only Trennick was forgotten. Coming back to the door, the servant was carrying the gun that Ardlan had told

him to get, but he was stopping, stupefied, as though he did not know how to use the weapon.

TWO men had so far been mistaken: one was Professor Ardlan; the other, Vic Marquette. Both thought that

They didn't; nor did The Shadow expect them to do so. He hadn't fallen into the error shared by Ardlan and

He knew Crumpf for what he was a tool employed by Rufus Bradwell to get at Professor Ardlan's

invention; whether to destroy it, merely injure it, or simply learn its secret, were matters to be studied later.

The case was obvious, considering that Bradwell had taken spectacular pains to remove Jerry Croft, the one

Certain it was that Crumpf and his pals were smooth and calculating workers; otherwise, Bradwell would not

have hired them. At least, Crumpf was on a par with Hortland, and The Shadow could bear witness to

Hortland's punch in a pinch. He knew instantly how Crumpf and the men with him would react when snared:

Crumpf didn't have to yell at the others. They were on the move as quickly as he. Marquette, Ardlan were

forgotten. Three guns were swinging for The Shadow, shoved ahead of the men who held them, as all made

His leap from the stairs was something phenomenal. One quick step downward gave him impetus; with the

advantage of a higher level, he must have traveled close to twenty feet in the broad jump that he made or

would have carried that far, if he hadn't encountered human obstacles on the way.

In the time space that Vic had allowed for The Shadow to beat two marksmen, the master fighter had outdone

all three, for his flying drive carried him right into the surging cluster and scattered them wide.

Floundering backward, the men thwacked the walls and floor, their guns tonguing upward to the ceiling. The

Shadow was through them, and beyond, when they rolled to their feet and made a mad dash for the stairs, not

ON his feet, Vic Marquette was following The Shadow. So was Professor Ardlan, a few seconds later. In the

time that Vic took to snatch up his lost gun, Ardlan acquired a weapon, too, by snatching his own revolver

Ardlan took the additional seconds to boom an order at Trennick, telling the servant to close the laboratory

door and turn the combination dial. Then, with long strides, the shaggy professor was hurrying after

During the trip up the stairs, Vic realized the soundness of The Shadow's strategy. The cloaked fighter

couldn't have risked shots at Crumpf and the others when they surged. Had they been apart, in a room, The

Shadow's system would have been to shoot at two, crippling them, while making a quickfading dodge as a

had been an impossible place for The Shadow to stage a fadeaway. It seemed that every time Vic saw The

Vic was to learn more, very shortly; it was unfortunate that he didn't foresee the fact.

The front door was wide when the Fed reached it, and the fugitives were outside, scattering across the street.

The Shadow was taking a long bound down the front steps, his automatic poised as though deciding upon a

Changing direction, The Shadow took a sudden dart between two trees. He wasn't after the nearest man; he

was picking the most important fugitive, Crumpf. The Shadow fired, his laugh echoing with his shot.

Crumpf faltered, but did not stagger. The bullet had whined a half inch past his ear, enough to discourage

anyone's idea of flight, which was what The Shadow wanted. His plan was to take Crumpf alive.

Vic's gun was talking now, but uselessly. He'd picked another man; too late. The fugitive was too far away

Professor Ardlan wasn't shooting. From the way he squinted, he couldn't see very well in the darkness. The

man that Vic failed to get reached a car some fifty feet down the street. Vic looked for the third man and

Before Vic could aim, a young man sprang from an arriving taxicab and sprang for the third crook. He

grappled with the fellow, trying to wrest away his gun. Marquette recognized the arrival as Jerry Croft and

Jerry did, but only after a reeling struggle halfway to the waiting car, and it was only because Jerry tripped

Running beyond the trees, the fugitive reached the car and jumped into it. The car started, carrying the two

men away. Marquette fired a few wild shots after it, and so did Jerry, for he had gotten what he wanted: a

They were grappling in what seemed a furious style, and Crumpf, to Vic's amazement, appeared to have the

advantage. He was actually driving The Shadow ahead of him, back across the street toward Ardlan's front

IT should have occurred to Vic that such wasn't the direction Crumpf wanted; that, in reality, The Shadow

was hauling Crumpf back with him, intending to toss him, exhausted and defeated, right at Vic's own feet.

For the present, Vic's only idea was to help The Shadow; and the same thing occurred to Jerry, on the other

Jerry saw his opportunity and fired, winging Crumpf, who was on the side toward him. The Shadow wheeled

Crumpf about, thinking that Vic wouldn't make the same mistake; but the Fed did. He gave Crumpf a second

To offset further folly, The Shadow gave Crumpf a lunge, hoping he would sprawl and thereby show that he

was helpless. Crumpf staggered, which was enough for Jerry and Vic, but his reel was in the direction of the

Crumpf collapsed in the middle of the front walk. Marquette dashed out into the street to commandeer Jerry's

cab, and the young man joined him. Together, they sped away, hoping to overtake the other fugitives.

Professor Ardlan, stopping a few moments to look at Crumpf, continued as far as the sidewalk, but arrived

To all appearances, Crumpf was dead; but The Shadow had tried too valiantly to keep the man alive, to give

up the last shreds of hope. He glided up beside Crumpf's coiled form; stooped, and lifted the fellow's head.

Crumpf's goldchained glasses were gone, but they had only been part of his makeup. His gaze was clear,

There was defiance in those eyes. The Shadow used the system that he had tried with Hortland.

"Vi venis al la domo," spoke The Shadow, in a low tone, "difekti la provo kio estas en la laborejo." ("You

came to the house," spoke The Shadow, in a low tone, "to destroy the invention that was in the laboratory.")

Dying eyes still held their stare. Either Crumpf did not understand the language, or he was too obdurate to

answer any questions, even from The Shadow. Again, The Shadow spoke, this time in English:

There was a glitter in Crumpf's gaze. His lips opened; then, between clenched teeth, he gritted:

The response did more than tell that Crumpf was familiar with English only. The denial was practically the

same as "Yea," though Crumpf did not realize it. To really deny Bradwell's part, Crumpf should have shown

no recognition of the name; but his fading intellect hadn't rallied to that point.

He was being loyal to Bradwell, who hadn't doublecrossed him, as Malga had with Hortland. But loyalty, in

At least, Crumpf's warped conscience helped to ease his death pang, for a moment later, his eyes went glassy

and his head slumped, but his gritted teeth held an expression which might have been termed a smile.

THE taxicab was returning from a trip around the block, for Marquette and Jerry had found no sign of the

Moving to the steps, The Shadow merged with the door's blackness. Finding the door still unlatched, he

The Shadow let the door ease shut, because Trennick was turning to lock it. Gliding off into darkness, The

Shadow gave a whispered laugh a tone that might have been a knell for Crumpf, whose death was to be

But there was a tone of satisfaction in the final quiver of The Shadow's undertoned mirth. It certified Ardlan's

For The Shadow's easy glide, his pauses, proved that he did not intend to travel far. Instead, he was assuming

a duty; he intended to patrol this neighborhood in person, and make certain that no new attempt would be

made, by others, to complete the design at which Crumpf and his companions had failed.

UNFORTUNATELY, The Shadow's vigil did not include a watch within Ardlan's house, itself. He was

leaving that to Marquette, Jerry and Trennick. But the first two were not keeping tabs upon the third.

Professor Ardlan had gone into the parlor to talk with Vic and Jerry. As a matter of course, Ardlan closed the

It was Trennick's opportunity. Reaching the telephone, the servant dialed the same number as the night

As Trennick hung up, a sneering chuckle was audible from the descending receiver; it was identical with a

The tone of Kurd Malga, who had balked The Shadow by killing Hortland, and was confident that he had

BY noon the next day, reports of Ardlan's coming test had spread through official Washington and reached

the newspapers. Congressman Anderton had ended a dilemma by making the facts public. As he put it to

Cranston, who dropped into the apartment around noon, there had been no other choice.

"The professor wants a million dollars appropriated for the benefit of humanity," explained Anderton. "At

first, he wouldn't hear of doing things any other way. My mention of congressional committees made no

"What I did tell him" Anderton gave a rather pleased smile "was that the act of voting through an

"I argued that it would be better to prove the invention's merit, and deliver the apparatus to the government

for safekeeping. Afterward, the appropriation would come in due course as I actually believe it will.

Moreover, I see no reason why the war department would hesitate to give the device to other nations, as

"Our national policy is one of defense, and we have encouraged other nations along that line. America is

opposed to war, and anything that can nullify the horrors of war should be extended to those who need it. My

one hope" he shook his head "is that Professor Ardlan is not as crazy as he sometimes appears to be."

A scoffing voice interrupted. Rufus Bradwell had arrived, and the secretary had sent him into the study.

"You have only seen Ardlan in his milder moods," Bradwell told Anderton. "Like yourself, I hope that the

test succeeds, but knowing Ardlan and his eccentric ways, I am short on confidence. By the way, Anderton, I

This was The Shadow's first look at the chauffeur, and one glance told him that the fellow was a rat a fact

which Bradwell calmly ignored and Anderton failed to discern. However, when Anderton shook hands with

"I really did very little, sir," said Winstle. "I fought off one ruffian and managed to get the car away, but I

made the mistake of thinking that Miss Anderton was still safely in the car with Mr. Croft."

"They saw a cab and took it," explained Anderton. "Otherwise, they would have stayed with you. In any

Winstle started to say something, then glanced at Bradwell, as though taking a cue. The grizzled man clapped

"You're going to drive us to the proving grounds, Winstle," he said. "That shows how much we think of you."

Soon after Winstle had gone, Ruth entered the study. The girl was jauntily dressed and her hair was freshly

curled. There was no denying that she was attractive, though she would have described it as allure.

Her getup was unquestionably for Jerry's benefit, because she passed by Cranston and Bradwell with a

"No," replied Anderton. "He and Croft are bringing the Neutralizer out to the proving grounds in a truck."

Without knowing it, Anderton had answered the question that Ruth really wanted to put: namely, why Jerry

had not come. Bradwell looked toward The Shadow, who considered it good policy to supply the slight smile

THEY rode to the proving grounds in Bradwell's limousine, and as soon as they arrived there, Ruth strolled

over to a parked truck and watched the driver open the doors in the back of it: She expected to see Jerry

They didn't merely go "baaaaa!"; they lowered their horns and made for the spectators, and Ruth joined the

general scramble for safety. However, the goats were wearing ropes, and their keepers hauled them in before

The goats were dragged to the center of the flat arena and tethered around a great sack that hung from a high

pole. The thing looked like a cross between a giant hornets' nest and a small balloon.

Soldiers measured the ropes, to make sure that the goats were within the required radius, and before they had

finished another truck came through the circle of surrounding cars and rolled up beside the pole.

This time, Jerry did step out, along with Vic Marquette and a few other Feds. Ruth couldn't find a chance to

speak to him, because soldiers were ordering the crowd back. From the truck, Jerry and the others brought the

professor's famous invention, and unveiled it directly beneath the mammoth hornets' nest.

The soldiers checked the ropes again, to make sure that the goats were not close enough to ram the machine

In fact, the goats had become quite ludicrous in behavior, and even tried to butt the truck when it pulled away

from among them, much to the amusement of the crowd. Merriment increased when Professor Ardlan arrived

on foot and had to dodge between the bewhiskered creatures that were to help his test.

Sight of the shaggyhaired professor, zigzagging between the goats, was really very funny to everyone but

Ardlan. When the crowd echoed the "baaaaa" of the goats, Ardlan showed indignation. Forgetting the goats,

This was to be serious business. Maybe the lives of these very onlookers would some day be in jeopardy,

hanging by the thread that Ardlan's invention represented. The newspapers had rushed special editions, and

hadn't missed a trick in covering the possibilities of the gas Neutralizer; hence everyone was familiar with the

Poison gas, most horrible of war weapons, would be a forgotten menace if this test went through. There

would be one in every home, in every bomb shelter; they could be used in tanks, submarines, and other

military conveyances. Hospitals would find them a boon in protecting the wounded.

The Neutralizers, as experts pointed out, would be far more than a substitute for gas masks. They wouldn't

just protect people against poison gases; they would eliminate the gases, through neutralization.

This was of vital importance, considering that certain deadly gases, as yet little used in warfare, were known

to be odorless and therefore dangerous before gas masks were put on, or after they were taken off.

The Neutralizer, according to Ardlan's claims, could detect such gases automatically, and not only proclaim

their presence, but dispose of them. So it behooved the people who watched the test to show more sense than

Standing by Bradwell's car, The Shadow watched the professor's preparations. Bradwell was chatting with

Congressman Anderton, but The Shadow noticed that Bradwell's eye was occasionally on Jerry Croft, who

had come over to the car. At first, it had seemed that Jerry intended to speak to Anderton, perhaps to make

some pointed remarks that Bradwell might have understood. But Ruth had flagged Jerry, and was talking to

Maybe Jerry would have had a sharp eye for Winstle, too, had the chauffeur been around; but he was not.

Winstle had run into some acquaintances the chauffeurs of other cars and had gone somewhere with

A LOUDSPEAKER began to blare above the proving grounds, telling everyone to move back to a distance

of at least fifty yards. Soldiers were putting the order into effect. As the loudspeaker lulled, The Shadow

the whir of its fans, could not, however, be heard at that distance; nor did the lights show against the sun,

The professor pressed a final switch, and turned about. Two soldiers made a path for him, by tugging back a

The professor's approach gave Jerry his chance to break away from Ruth. He spoke a reminder to Ardlan:

"Yes, Jerry." Then, to the others: "It was the last thing you saw me do. Ordinarily, I manipulate the machine

A long cord had been carried from the gas bag atop the pole, to a spot where a cluster of army officers stood.

present visiting Washington. They had been invited to view this important test, which might prove so great an

capable of viewing the result that the other onlookers saw. The blanket had leveled to a mere layer along the

WITH a bellow of unbelief, Ardlan stumbled out toward his machine. Jerry leaped after him to draw him

back, for the ground was not yet safe. Savagely, the professor tried to keep ahead, and it took two soldiers to

help Jerry restrain him. Anderton turned to Bradwell and said, in a sorrowful tone:

Bradwell agreed. His face looked as long as Anderton's. Perhaps The Shadow might have noted that

Bradwell's gloom was not genuine, but it happened that The Shadow was not about.

Winstle had just returned, and The Shadow was moving swiftly in the direction from which the chauffeur had

come; though, as Cranston, he managed to keep his speed from being too apparent.

"Come, Ruth," said Anderton, to his daughter. Then, looking about, he questioned: "Where is Mr. Cranston?"

"He said he was going to meet a friend," the girl replied, "and ride back to town with him."

Ruth was looking toward Jerry, who was still engaged in humoring the professor. Ardlan was gesticulating,

tearing at his shaggy hair, and to all appearances would be a real problem for some time to come. So,

Some cars were already leaving the proving grounds, and it was toward one of those that The Shadow

hurried. He wasn't in time to overtake it, for it spurted through a gateway out to the road. But he was in time

One, that of the driver, was the grinning, skullish countenance that belonged to Kurd Malga; the other, bulgy

of forehead, belonged to the man who served as leader of Malga's strongarm crew!

There were two more of the tribe in the back seat, but The Shadow did not care about the odds. All that he

needed was a car, and people who noticed Cranston saw him turn suddenly, and spring into a coupe that a

The young man happened to be Harry Vincent, one of The Shadow's secret agents, posted here for just such

Other cars, however, intervened between Harry's and the gate. The delay made it impossible to overtake

Malga and his men. Easing back in the seat, The Shadow spoke in Cranston's quiet tone.

"You saw what happened, Vincent," he remarked. "This does not mark the end of our interest in protecting

There was a grim touch to those calm words, which told Harry that he could expect special instructions as to

the part he was to play. So far, The Shadow had played a lone hand, seemingly to perfection, yet his efforts

It would require more hands than one to get to the bottom of the riddle which had resulted in the failure of

Ardlan's great invention; for the ways of the opposition were many. They had spoiled today's test, despite

With such men in the game, neither Professor Ardlan nor his invention would be safe until the perpetrators of

JUST after dusk, Jerry Croft entered the World Wide Cafe and took a table in the corner. This was the second

time he had been in the place, but this evening he did not expect to meet Professor Ardlan.

Jerry had just left the professor at his house; he had come here hoping to meet the men that he had found

That the man with the bulgy forehead and his companions were in some wise responsible for the failure of

Ardlan's Neutralizer seemed quite obvious to Jerry. As obvious as the fact that Rufus Bradwell, the grizzled

millionaire with the toowise smile, must be the man behind the whole dirty game.

Things had looked all right last night, when Crumpf and a couple of stooges had come to grief trying to get at

the Neutralizer; but it was Jerry's opinion and one that seemed indisputable that Crumpf and his pals had

Their visit, Jerry decided, must have been intended as a failure; because, by their fluke, they drew suspicion

If Jerry had ever seen Kurd Malga, the man with the grinning death's head, he would have credited, or

discredited, the fellow with having done the job, for Malga looked the part of the archconspirator that he

was. Yet, there would still have been the riddle of how Malga, or anyone else, could have gotten at the

It never occurred to Jerry that the thing might have been an inside job, engineered by Ardlan's faithful

None of Malga's strongarm men was around the World Wide Cafe, though Jerry looked everywhere. He

listened for snatches of the strange language that he had previously heard, but no one was speaking it. Even

the tawnyfaced waiter was absent; either it was his night off, or, more likely, he had quit the job.

A chair scraped beside Jerry; he turned with a start, reaching for the gun that he had been carrying since last

Superficially, the congressman's daughter had a mood to suit every occasion, with an extensive wardrobe that

matched. Last night, she had tried to impress Jerry by being coy, convivial and, finally, trusting.

Not having clicked, she had used a new technique this afternoon a straight girlish pose, tending toward the

outdoor type. She hadn't made a dent; to Jerry, she had simply been part of the scene, like the lamented goats.

Her present course was to appear confidential and mature. Stunningly gowned; Ruth was a creature of

loveliness, her eyes dancing, her smile friendly instead of saucy. Her snub nose was offset by the tilt of her

chin, and, in all, Ruth was putting on an excellent act. But it was an act and nothing more, as Jerry could tell,

Ruth was out to make a conquest, and was using every wile. It was plain that she wanted to break down

Jerry's reserve, or indifference, whichever it might be, before she began to cast new eyes upon eligible young

men who came her way. Hence Jerry, quite sure that he saw through the game, did not feel at all honored by

Nevertheless, he covered his annoyance and became quite polite. He accepted Ruth's pretext that she had just

chanced into the World Wide Cafe, though he was quite sure that the restaurant did not belong on any

He'd tried to indicate that his lack of interest was actual; and since Ruth wouldn't accept that answer, Jerry

"I thought surely that you would come to father's apartment," she said. "He doesn't blame you because the test

To Jerry, that was as bad as if the blame had been placed on himself, but he didn't say so. He foresaw that if

he let Ruth talk long enough, he would eventually have cause to tell her off. So Jerry inquired, quite blandly:

That told Jerry something else. Jerry had told Ardlan that he was coming to the World Wide Cafe, though he

hadn't mentioned why. Ardlan must have informed Anderton, which was how Ruth had located Jerry.

"What did the professor have to say?" asked Jerry, casually. "Anything important?"

"I don't know," returned Ruth. "He was busy trying to get his silly invention working, as if it ever could! Dad

The news pleased Jerry, even though its bearer did not. He wouldn't have left Ardlan at the house if he hadn't

known that Marquette was due. In Jerry's opinion, Trennick wasn't enough protection for Ardlan.

Had Jerry known of Trennick's affiliations, he would have realized that the servant was no protection at all.

Most important, in Jerry's mind, was the fact that Professor Ardlan was overhauling the Neutralizer, testing

On the way back from the proving grounds, Ardlan had become himself again, and stated, with a positiveness

that impressed Jerry, that someone must have switched portions of the integral mechanism without actually

injuring it. In a case of straight sabotage, the professor argued, the Neutralizer would not have operated at all.

Such logic could not be disputed. Neat tampering, of a sort that even Ardlan had not recognized, smacked of

Bradwell's work. To Jerry, it also pointed at others the man with the bulgy forehead and his company

who, despite their strongarm tactics, were subtle enough to use a mysterious language whenever they

Jarring Jerry's reflections came Ruth's voice, which someone else might have likened to a lovely coo, but

"You haven't ordered dinner yet," the girl said. "Why don't you come and have dinner with us? I know that

Jerry was almost inclined to accept the invitation, simply because it would afford him other company than

Ruth's alone. He felt, too, that Ruth's attentions toward him could easily be interpreted as an infatuation, even

By making the case evident, it might be possible to convince the congressman that his very charming

daughter should bestow her affections upon someone other than Jerry Croft. So Jerry, seeking a direct way

out, began a slow nod, which Ruth regarded as a halfway acceptance of the invitation.

Just then, a waiter approached the table. He wasn't the phony that Jerry had been watching for, but he was

JERRY sat back with a sigh of relief. He was watching Ruth navigate around the corner that led to the

telephones, admitting, despite himself, that she did have charm, when he heard another scrape of the chair.

Turning, Jerry saw a young man, not much older than himself, sitting down beside him.

The fellow looked affable. When he extended his hand, Jerry gripped it and felt that the shake was sincere.

"My name is Vincent," remarked the stranger. "Harry Vincent. I framed that telephone call. Suppose we slide

out of here together, and talk over some matters more important than those that Miss Anderton wants to

The idea intrigued Jerry. He'd been looking for a way to irk Ruth, and no other could be better. Furthermore,

Still, as they walked from the cafe, Jerry was on guard, until he saw that his new acquaintance was simply

piloting him to another restaurant around the corner. As soon as they were seated, in a small booth, Jerry

He wanted to find out if Harry happened to be a real rival for the girl's affections, or simply someone who

had been taken over the hurdles like himself. Hence, Harry's reply actually astonished him.

"Why did I drop in on you?" Harry smiled. "I did so at the request of a mutual friend."

The term explained itself. Jerry knew at once that Harry referred to the blackcloaked fighter who had

intervened on three occasions in behalf of himself and Professor Ardlan. Inasmuch as he trusted The Shadow,

Only for a moment did Jerry's thoughts flicker back to the World Wide Cafe, where he could picture Ruth

Anderton being as greatly annoyed by his departure as he had been by her arrival.

In the cafe, Ruth was irked even before she left the phone booth, for the wire had been dead. She had kept

When she left the phone booth to look for Jerry, only to find him gone, Ruth stared, puzzled, at first; then

Quite confident of her charm over men, she merely supposed that Jerry had accepted her invitation and

started to the Anderton apartment, misunderstanding that she intended to accompany him. So she went back

"Hello. Raymond?... This is Miss Anderton. If Mr. Croft arrives; tell him to wait... Yes, I shall be there soon.

And remember, Raymond, you are to state what I told you earlier... Yes, that Professor Ardlan is in

Satisfied that such misinformation would keep Jerry at the apartment until she arrived, Ruth left the phone

booth. Continuing out of the World Wide Cafe, she almost brushed shoulders with a stocky, mustached man,

The darkish man happened to be Vic Marquette. Jerry thought that he was at Ardlan's but Vic wasn't. Having

learned that Jerry had gone to the World Wide Cafe, Vic had come there to find him; because the restaurant,

Like The Shadow, the Feds had learned much about a foreign operative named Kurd Malga, and had spotted

MEANWHILE, in the restaurant around the corner, Jerry and Harry were progressing nobly. As a friend of a

When Harry asked why Jerry had originally gone to the World Wide Cafe, Jerry produced the telegram that

"That's how the bunch picked up your trail," said Harry. "Tell me, what do you know about them?"

"Not much," rejoined Jerry, "except that they spoke a strange language, one that I couldn't identify."

Nodding, Jerry reached for his notebook. He felt that he was on the verge of discovering something important

which was, in fact, the case. For Harry Vincent, agent of The Shadow, was quite qualified to interpret the

tongue in question. Yet there was something that neither Jerry nor Harry recognized.

While problems of the past were being discussed, problems of the future were in the making. Problems that

RUTH ANDERSON, flaunting from the World Wide Cafe, was but a pawn in the game that was to come; yet

her moves, though seemingly innocent, were to prove of vital consequence. Still, she hadn't an idea of the

grimness behind her mild flirtation with Jerry Croft; how it was to be used as an instrument of murder.

In fact, Ruth was not only gay, but confident, as she called a cab and told the driver to take her to the

apartment hotel. She was sure that Jerry had already started there, and that soon she would have the

opportunity to make him pay some actual attention to her, after which, she could cross him off the list.

Vic Marquette was another pawn. He had been moved out of position. He should have stayed at Ardlan's,

Vic had made a bad mistake by coming to the World Wide Cafe, and he simply added to the error when he

sat down and ordered dinner, in the belief that Jerry Croft would show up. In placing suspicion upon Jerry,

Vic was carrying himself far from the trail that involved a known fox, Kurd Malga, and an unknown one,

Two other pawns were Jerry Croft and Harry Vincent, but they were at least progressing in the Rendezvous

Restaurant, which was the name of the place where they had chosen to dine, in preference to the World Wide

Partly from memory, partly by reference to his notebook, Jerry was repeating words that he had heard

"Esperanto!" exclaimed Jerry. "I've heard of it. An international language, isn't it?"

"Precisely," replied Harry. "Perfectly suited to Kurd Malga and his tribe of spies. They are international

themselves, hence they have become educated in a common tongue. Besides concealing their individual

" 'I followed him from the station,' " translated Harry, who knew his Esperanto. " 'He is the man.' " Then,

"The waiter said: 'Oni audos vin,' " recalled Jerry. "I remember the words 'komprenas' and 'malbona' "

" 'People will hear you,' " interpreted Harry. "Probably the rest was: 'If anyone understands, it would be bad.'

Jerry studied the notebook. This time, he was positive that he had struck the crux of the thing.

"The man with the bulgy head said: 'Alportu al mi iom florbrasiketo,' and it must have been important,

because the waiter repeated it. He said: 'Florbrasiketo. Mi memoros.' Tell me, Vincent: what does

"He was ordering broccoli," he said, "because that is what 'florbrasiketo' means. The waiter was simply

Jerry shoved the notebook in his pocket. He remembered, only too well, that the waiter had brought an order

of broccoli. What Jerry had considered to be his best bet had turned out to be a dud.

REALIZING that he had heard the last of Jerry Croft's notations on the Esperanto conversation, Harry

"Tell me about Professor Ardlan," he suggested. "Does he still think that he can get his invention working?"

"Absolutely!" returned Jerry. "He's been working on it all afternoon. He's going to give it a private test this

"Someone must have tampered with it. And yet well, Crumpf and the pair with him didn't get at it."

"Not even Trennick." Jerry paused suddenly and snapped his fingers. "Wait, though! Trennick could have!

The professor left him in charge of the lab, last night, while it still was open. Marquette mentioned it."

"But he told him to close the strong door." Harry was repeating facts given him by The Shadow. "Or did he?"

"He did," assured Jerry. "But Trennick was just coming up when Marquette and I came back from the chase."

Harry was elated. This was the very point that The Shadow had wanted him to check. Analyzing the

invention's failure, The Shadow had considered the inside possibilities and had divided them between Jerry

"You're sure that the professor is safe at present?" queried Harry. "That Trennick, if working with Malga, will

"How can he?" returned Jerry. "Marquette is there, down in the lab with the professor. Ardlan expected

Marquette to join him. Since the invention failed, Ardlan is less secretive about it."

"Of course. We can go to the house as soon as we finish dinner. Ardlan will be glad to receive any friend of

Harry decided to telephone The Shadow, to tell him how well he had progressed. Learning Jerry's story, and

arranging an introduction to the professor, had been the two things which The Shadow had told Harry to

SEATED in the reception room at Congressman Anderton's apartment, Lamont Cranston reached for the

telephone when Raymond, the secretary, handed it to him. He heard Harry's report, and approved it in his

quiet tone, without letting Raymond catch enough of the conversation to know what it was about.

Finished with the call, and having told Harry to get over to Ardlan's as soon as convenient which Harry said

would be very shortly The Shadow turned toward Raymond, made a Cranston gesture in the direction of

"I really don't know," replied the secretary. "You see, when Mr. Bradwell came "

"Yes. That is, he came after the professor arrived or perhaps before. I'm... I'm not exactly sure "

Cranston's eyes caught those of the secretary and held them with hypnotic effect. Under the accusing gaze,

"I... I lied to you," he confessed. "Professor Ardlan isn't here. He didn't come at all. I wouldn't have told you

"Call Ardlan's," spoke The Shadow in Cranston's firm, but calm tone. "I wish to talk with him."

Hurriedly, Raymond dialed the number, hoping to lessen the wrath of those burning eyes.

Clinging to the telephone receiver, Raymond nodded. He hoped that the number would hurry and answer; but

In the midst of those pressing moments, the door of the apartment opened and Ruth Anderton entered. She

saw that Raymond was using the telephone; ignoring Cranston, she hurried over to the secretary's desk.

"If it's Mr. Croft," the girl exclaimed, "tell him that Professor Ardlan is here, and wants to see him. It's very

Raymond's despairing glance turned to a savage glare in Ruth's direction. Like Jerry, the secretary felt

inclined to wring the swanlike neck that emerged from the collar of Ruth's brocaded gown.

An hour or more ago, Ruth had instructed Raymond to tell all callers that Professor Ardlan was in conference

with her father; her purpose having been to include Jerry in the hoax, and thus bring him to the apartment.

Having applied the rule to Cranston, who had finally uncovered the deception, Raymond's plight was worse

than Jerry's, for the secretary felt that the girl's meddling in his business might cost him his job. Ignoring

"The number doesn't answer, Mr. Cranston. I'm terribly sorry! Really, if I'd only realized that you wanted to

see Professor Ardlan, not Congressman Anderton, I wouldn't have misled you. Since the number doesn't

"It's not your fault, Raymond," returned The Shadow. "I understand who is to blame."

Ruth threw a piqued glance. She wasn't going to take criticism from anyone, not even from this Mr. Cranston

whom her father seemed to regard as important. In importance, Ruth came first, or, at least, she thought she

"Call Mr. Marquette. You will probably find him at the World Wide Cafe. Tell him to return to Ardlan's at

once. You won't have any trouble getting Marquette. They page people very promptly at the World Wide

amazed her, as did his insight into Jerry's sentiments toward Ruth, an attitude which the girl was reluctantly

But Ruth had no time for a reply, even if she could have thought up one. Turning, Cranston was gone with

THE SHADOW had reason to be off. Dusk had come again to Washington, and night was a time when crime

would be on the move. Protection of Ardlan was paramount, much more so than the guarding of the

professor's invention, which could be duplicated from his own brain, so long as Ardlan lived.

Hoping for a chat with Anderton, who might have furnished certain leads, The Shadow had left Ardlan's

protection to Jerry Croft, and later to Vic Marquette. Though learning, at Anderton's, that Jerry had gone to

the World Wide Cafe, and suspecting that Vic might follow, The Shadow had still remained in the belief that

But Ardlan hadn't come there at all. By rights, he must be at his own house, where there had been no answer

to The Shadow's call. Ardlan alone with Trennick, the man that The Shadow mistrusted as crime's worst tool!

In a car that he had parked near Anderton's, The Shadow was speeding for Ardlan's, no longer in the guise of

Cranston. He was cloaked in black, the garb that he might need when he reached his destination.

Though Ardlan's test had failed, the professor's persistence was the sort that would win him another chance, if

EVER since Vic Marquette had left the old house, Professor Ardlan had been coasting toward the brink of

death, though he did not realize it. In fact, Ardlan's mind had been solely concerned with thoughts of life. He

was alone in his laboratory, with the door locked, and he had his invention working.

Colored lights were responding to the dials that he manipulated, while a tank in a corner of the room was

emitting a sizzle of mustard gas ordinarily deadly, but neutralized when the professor's machine was in

On a table was a box of guinea pigs; Ardlan plucked one of the cavies from its nest and held it close to the

When the guinea pig showed no ill effects, Ardlan laughed and stepped past the flow himself. He put a tag

around the guinea pig's neck, labeling it as a specimen of life that had survived mustard gas.

Turning off the corner tank, he went to another large one that bore the deadly legend: "Phosgene." He

watched the bubbling cease from a glass container at the side of the Neutralizer, then turned on the phosgene.

Thumbing the dials of the machine, he waited calmly for its identifiers to show results upon the blinking

At that moment, above the slight hum and swishy whir of the Neutralizer, Ardlan heard a knock at the door.

Ordinarily, Ardlan didn't answer knocks while busy with a test. His lapse on this occasion was almost

accidental, occurring probably because he had just finished with one gas and was starting with another.

Ever cautious, Ardlan would have asked Marquette to speak for himself, except for two chance factors. The

first was that Ardlan, far from suspecting Trennick to be a traitor, trusted the servant much more than before,

for he considered Trennick's actions on the previous night to have been a display of loyalty.

The second factor was the phosgene. Not only was Ardlan's mind back to the dials of his machine, but he

remembered that Marquette had once asked him if his invention could neutralize phosgene. This was just the

It wasn't Marquette who entered. The man admitted by Trennick was thickset like the Fed, but he had a much

different sort of face. One, indeed, which could scarcely he classed as a human countenance.

Thrust boldly into the light, it looked more like a grinning skull, until Ardlan squinted and saw that it did

This was Ardlan's first meeting with Kurd Malga, who had decided to take a personal hand in matters, having

PROFESSOR ARDLAN was active, as he had demonstrated when he dodged the goats. He shot a long arm

forward, so rapidly and suddenly, that he had barely time to close his fist before it struck squarely in the

Malga stopped the slam, almost getting the door in the jaw. He had come back from Ardlan's punch as if

actuated by a springboard, the reason being that there were two men behind him, who propelled him forward

One was the bulgybrowed man that Jerry hadn't liked; the other, the tawnyfaced waiter who had formerly

worked at the World Wide Cafe. Darting away from the ugly three, Ardlan made for the desk in the far

Trennick was telling Malga that Ardlan had a gun in the desk. Had the professor recognized it, he could have

gotten the weapon, for Malga and the other two were trying to corner him in crafty, rather than hasty style.

But Ardlan didn't understand the language, whereas the words in Esperanto were plain to Malga and his men.

Professor Ardlan had shown power that afternoon, when he had started a suicidal dash toward the dead goats.

He demonstrated it again, flaying his attackers right and left, almost landing them against his precious

machine, which was humming away, its lights still blinking, while a hiss came from a corner of the room.

Skirting the contrivance, Trennick reached the desk and grabbed the gun from the drawer just as Ardlan came

reeling back to get it. The professor changed his motion to the servant's direction.

Coming in from a chance angle, Malga intercepted him. With bony hands that suited his skullish face, Malga

caught Ardlan's chin and neck and gave a hard twoway twist. Ardlan spun as if Malga had twirled a top, and

Trennick, a moment later, received evidence of the jujitsu skill which the master of the spy ring possessed.

Trennick, about to pour bullets into the coiling form of the shaggy professor, found his hand numb, his

fingers askew, with the gun barely dangling from them. Malga had given the traitor's wrist a neat twist.

He was calling Trennick a fool who would spoil their purpose, and the fellow understood, very shortly. While

stooping to pick up the revolver, Trennick stared at Ardlan and saw that the shaggy man was lying, quite

stunned. Then, one of Malga's companions, the tawny exwaiter, was pointing to the Neutralizer and

Malga looked, and widened his lipless grin. The lights on the device had stopped blinking. Malga snarled

suddenly, as the machine behaved automatically, diamond lights on one side of the dial matching those on the

other; but when he beckoned to Trennick, the servant settled that little matter.

Trennick knew where the right switches were, and he pulled them. He thumbed dials to make the lights

It meant "do some more," and Trennick did, by tilting the top of the machine and changing the first plugs that

Professor Ardlan was staring up from the floor, for his eyes had opened; but as yet, he could not move.

All the while, Trennick was panting words in Esperanto, telling Malga that a deadly gas was filling the room.

Satisfied, Malga beckoned for the servant to come along. As they joined the others, who were out in the hall,

Malga threw a savage glance at the professor, whose eyes, by then, had closed again, purposely.

SCARCELY had Malga slammed the door and started to twist the combination dial, when an answering echo

Trennick gasped that it must be Jerry, and Malga gestured to the gun that Trennick held, telling him to use it.

Raising the weapon, he gave a shout for help and fired at the ceiling. Like racers, Malga, and his two pals

They went up the stairs brandishing their own revolvers, only to be met by two men, instead of merely one.

Jerry had brought Harry along, and what was more, both had guns. All that fooled them was the clatter from

Accordingly, Harry and Jerry made a wise dodge for the parlor, as they fired their first shots.

Those shots were wide, but it didn't matter for the moment. The parlor was dark and afforded perfect shelter,

from which they poked their guns anew. The shots had halted the arrivals from below, and Harry yelled out.

From the doorway, Harry saw Malga and recognized the fellow from the glimpse of that afternoon. In his

turn, Jerry spotted the bulgyheaded man and the tawny waiter, hence knew that the halted men were

Hands were going up, guns drooping from loosening fingers, when Malga pulled the unexpected.

The unexpected happened to be the dangling light cord in the hall, which came luckily into the grasp of the

Guns blasted in that blackness, with men dodging everywhere, Harry and Jerry among them, for they heard

one man, probably Malga, come diving frontward, hoping to take a pot shot into the parlor.

Harry, more used to battle than was Jerry, knew that the front door was the proper target, for it was the

probable exit that the spies would choose. But as he swung, Harry encountered Jerry and had to give him a

It didn't amaze Harry. He knew exactly what had happened. Instinctively, The Shadow's foemen had dodged

for cover as they fired, and the cloaked marksman hadn't given them time to stop. Every man in the charging

cluster, Malga included, thought that the swift stabs were meant for him, alone, and none wanted to bear the

The Shadow wasn't halting his motion, nor his fire. He was skirting in toward the house, his guns going full

blast. Only one shot seemed really wild; it nicked the front door in back of Trennick's ear, and in so doing

It stopped Trennick's original intention to shoot at the backs of Harry and Jerry, the men just below.

Dodging back into the doorway, Trennick decided that he'd better square himself.

Harry was pumping shots in the general direction of the Malga group, and Jerry was just a trigger pull behind

him. Trennick joined their barrage, pushing out into plain sight to convince The Shadow that he was quite

loyal. Of course, Trennick was firing wide purposely, but he didn't make it too evident.

Malga and the rest were out in the street, a few of them stumbling badly. They were lucky, very lucky, and

probably Malga knew it. If it hadn't been for the plight in which The Shadow found Harry and Jerry, the

ranks of the spies would have been thinned by half, with most of the victims permanent examples of the

The Shadow had rushed matters in order to put his foemen on the run, knowing that they then would fully

forget their intended victims. In so doing, he had also obtained the sharpshooting services of Harry and Jerry,

both of whom were capable. The trouble was the trees, which had helped Crumpf's men to flee the night

Besides, The Shadow, having put the crooks to flight, was leaving the last touches to Harry and Jerry. He had

turned to place another shot at Trennick, so close that it almost scorched the fellow's cheek. It was a hint for

Another cue had come at the same moment, a strangely worded shout from across the street, given by Malga

to his men. From their moving cars, they blasted a firing squad at Trennick, who was now their only possible

Most of the bullets merely found the door into which Trennick had started, but a few winged the servant and

Trennick had played his part of pretended loyalty to Ardlan; very aptly, Malga had decided to give it the

The Shadow could have used the delay that Malga made, to wheel out to the street and take sure shots at the

departing cars, but he hadn't forgotten the major issue: the fate of Professor Ardlan.

Springing up the steps, he started into the house; and Harry grabbed Jerry, telling him to follow. Downstairs,

in the lighted passage, they found The Shadow hammering with a gun handle at the strong door. There was

Reversing his automatic, The Shadow blasted away the combination lock and chunks of the door's steel

sheathing with it. Fired from a few inches distance, the slugs from a .45 were handier and quicker than any

other method of entry. The door gave, and as it slung inward The Shadow reached out to restrain the two men

THE hiss of gas from the corner was louder than the whirring hum of the professor's Neutralizer. The room

wasn't safe, though Ardlan, on his feet beside the table that held the machine, was definitely alive.

Holding his breath, The Shadow sprang across the room, whipped Ardlan from beside the contrivance and

sent him on a long reel through the doorway, into the arms of Harry and Jerry, who hurried him toward the

Meanwhile, The Shadow reached the phosgene tank and turned off the gas. His breath still held, he took a

look at the Neutralizer as he passed it, saw that the device was not working. Grimly, The Shadow kept on his

Such things could be kept until later; the important matter at present was what Ardlan might have to say, for

his time was very short. At least, Jerry recognized it, for The Shadow, coming from the stairs, observed that

"Only a few wires, Jerry. That's... all I had... to fix. Should have... turned off the gas... first. But I forgot. Had

Ardlan paused to take a long, deep breath as he was lowered to a couch. Harry had turned on the parlor lights;

from the doorway, The Shadow saw a smile come to Ardlan's lips and freeze upon them. That was the way

with phosgene. Too many whiffs of it, and afterward the stuff would show its effect.

Odd circumstances had contributed to his passing from Ruth's meddling in Jerry's business, to the

professor's own folly. At least, Ardlan had died happy, for his whole aim in life had been to prove his

Still, The Shadow felt himself responsible for what had happened, for it was his way to calculate all possible

There was one that he intended to remedy, as far as he could. That element was Trennick. Moving out

through the front door, The Shadow found the dying servant just below the steps, where Marquette had

Such, to Trennick, was the significance of The Shadow's statement. Had the words been in English, Trennick

would have ignored them. A crook at heart, he would have preferred to keep whatever he knew to himself.

But he had been used to taking commands spoken in Esperanto, and habit could be an important factor in a

To a degree, reason played a part with Trennick. He judged that The Shadow's use of the special language

indicated a closer knowledge of matters than anyone supposed; that The Shadow might even have a hold

upon reactionary members of the group controlled by Malga. Such shattering of Malga's prestige made

Except for occasional choking coughs, Trennick spoke slowly, steadily, his words a jargon, for he was

"They came here," he said. "Malga and the other two: Baushon and Zuvar. Ili venis detrui!"

"They came to destroy," translated The Shadow. Then, his eyes revealing a sharp glint: "To destroy both the

"La profesoro unua," spoke Trennick: "The professor first. Poste, eble la inventajo."

Repeating those words, The Shadow showed by intonation that he understood them fully. Malga's system had

been crafty; by getting rid of Professor Ardlan, he had sought to dispose of the Neutralizer, too. He wanted it

to look as though Ardlan had died while attempting an unsuccessful test. Such a result would probably

Had Malga and his two pals, now named as Baushon and Zuvar, been able to leave the house before others

arrived, the scheme would have worked. Harry and Jerry, by their arrival, had precipitated battle, which was

unfortunate; for The Shadow, coming so closely afterward, could have saved the situation skillfully and

That, however, was a thing of the past. The Shadow was concerned with the future. He spoke to Trennick.

"Should anyone, Croft for instance, put Ardlan's machine into working order, then Malga "

The Shadow left the statement for Trennick to finish. The dying man picked it up.

"La revenos," croaked Trennick. "Yes. Malga will return. Li stelos la Senefikiganto "

He was saying that Malga would steal the Neutralizer, "Senefikiganto" being the coined Esperanto name for

"Malga will steal it... to destroy it... but he will hide his methods, as always. Malga has much other work to

There was a long gasp before the word "unknown." The Shadow propped Trennick to a better position beside

"I called Malga the night when Croft came. I told him that Croft had arrived safely; which surprised me. I

said that the invention was soon to be tested; that the next night would be the last opportunity to act "

"And Crumpf came the next night," prompted The Shadow, as Trennick faltered. "His purpose was to tamper

"When Crumpf failed," added The Shadow, "You did the task instead. But you had never seen Crumpf before

"Malga told you to let Crumpf proceed, but not to advise him that you, too, were in the plot "

Trennick inserted a weak nod, his eyes wide, at recognition of The Shadow's uncanny full knowledge.

Trennick would have stared harder, had he known that The Shadow was reasoning out facts that he had not

They found Trennick's body against the steps, but they saw no sign of the gliding shape that was moving

through the darkness. Nor did they catch the low, parting whisper that The Shadow uttered.

The cloaked investigator had profited from Trennick's dying statements. They had revealed facts which fitted

with The Shadow's own conjectures, though Trennick, himself, had not realized the importance of the

Within the house, Vic Marquette was pacing back and forth, glumly considering what to do next. He had met

Harry Vincent before, and connected him definitely with The Shadow, which was very fortunate for Jerry

Still, Vic was reasonable enough to recognize that he had made a mistake, himself, in following Jerry. Hence,

Jerry wanted to talk, but Harry wouldn't let him. In fact, Harry managed to insert a few words of definite

advice while they were going downstairs with Marquette and the other Feds, to have a look at the laboratory,

though, to admit that Trennick had also been shooting after the fugitives. Thus, when Marquette led the way

Indeed, Jerry would have been inclined to accept the theory, lifting Trennick from all suspicion of earlier

treachery, if it hadn't been for the open drawer of Ardlan's desk. He mentioned that point to Harry as they

were riding to Congressman Anderton's, where Marquette had told them to meet him, for further conference.

"They must have gotten into the lab," insisted Jerry. "They attacked the professor, and probably left him

senseless for a time. Only, he would have opened the drawer and besides, how could Trennick have gotten

It was sound logic, that Jerry backed by repeating Ardlan's dying statement. As Jerry reasoned, Ardlan

wouldn't have turned on the phosgene if the invention hadn't been working. The gadgets that needed fixing

were obviously ones that Trennick had altered hurriedly, after Malga and the others had overpowered the

THE remark was Jerry's. Harry already was sure that Trennick had talked, to The Shadow. The next thing

was for Harry to report other details to his chief. That opportunity was presented him at Anderton's.

Cranston was there, and Harry was able to mention the facts before Marquette arrived. He added that Vic had

left Feds on duty at Ardlan's, which was important, since Harry knew that The Shadow still regarded Ardlan's

Meanwhile, Jerry was telling the news to Anderton and Bradwell. In his deceptive way, Rufus Bradwell

seemed to share the congressman's grief over the passing of Professor Ardlan. It wasn't until Marquette

arrived that Bradwell showed his double nature, and even then, his way was too subtle to be criticized.

Marquette declared that the invention was definitely useless, basing his argument on an added finding that

Actually, it was the phosgene that had eliminated the guinea pigs that had survived the earlier tests. But Jerry

object, but hesitated, which proved fortunate. For Marquette, accepting the notion, turned to Jerry and

Eagerly, Jerry nodded. With Harry as a pal, Jerry was willing to defy any thrusts that might come from

Bradwell, even if Malga proved to be the instrument. Jerry knew that both he and Harry could depend upon

It was Harry who suggested that they return to the professor's house, and Marquette agreed. They started,

only to pause in the reception room, where Raymond, the secretary, spoke to Jerry.

A plan that boded ill for men of evil, judging from the sinister tone of The Shadow's whispered laugh!

NOT only did Rufus Bradwell issue a public eulogy in behalf of Professor Ardlan; he paid a visit to the dead

Reading it, Jerry could almost believe that Bradwell regretted Ardlan's passing. The tribute described Ardlan

as a humanitarian of vision, whose work might some day serve as an inspiration for other men of inventive

It was afternoon when Bradwell made his visit, and he went to the laboratory to look at the professor's queer

"My work is chemical research," replied Jerry. "I know very little about the professor's invention."

"Ah, yes," nodded Bradwell. "I had forgotten. I was going to say that I might use you, as a technician, along

with others who are working on a different kind of Neutralizer. I may have a place for you, anyway, Croft.

See me, after you have finished with your task of straightening poor Ardlan's affairs."

He handed Jerry a card stating his home address, in a fashionable section of Washington. When Bradwell left

truckers that they had made a mistake; that the furniture belonged in the house and wouldn't be taken along.

However, since they had brought the big truck, they decided to use it. The Neutralizer went into the back,

Marquette was around, and so were some curiousminded strangers who looked on from parked cars. Terry

had a hunch that some of them might represent Malga. Then Harry beckoned him into the rear of the truck,

and as it started, Jerry was surprised to find that the truck already contained a load in the shape of a bulky,

The next surprise was even greater. When Harry pulled away the covering cloth, he revealed, of all things, a

trim coupe of an undersized make of automobile, which was pointed toward the closed rear of the truck!

"Get the Neutralizer into the baggage compartment of the coupe," ordered Harry. "It will hold one of the gas

Watching through a peephole in the rear of the truck, Harry kept tabs on cars that picked up the trail. They

were on a road outside of Washington, turning a long curve, when Harry passed the word to the truck driver

The truck driver was Cliff Marsland, another of The Shadow's agents. Cliff picked up speed on the curve;

leaving trailers quite out of sight. Veering into a side road, he used the air brakes, bringing the truck to a

sudden stop. At the same moment, Harry released the brakes of the coupe. The rest was automatic.

A slight forward jolt of the truck sent the coupe rearward. The truck's whole back went downward on a hinge,

Harry had the car in gear as it hit the road; released, the truck's rear wall went up again on powerful springs,

As two cars swung into the side road, they passed Harry's and took it for a chance car coming the other way,

since the truck was rolling ahead, slackened apparently, because the side road was rough.

Harry and Jerry were safely away with the precious Neutralizer, while mysterious pursuers were on the trail

Veering back into Washington, the truck rolled into a garage, where Cliff and a companion left it. Other cars

had arrived; men from them watched the departure of the supposed truckers, then sneaked into the garage.

Faces showed in the light those of Baushon and Zuvar. They felt that they were absolutely safe, because

Boarding the truck, the pair found the Neutralizer and the gas tanks missing, with no sign of Harry or Jerry.

Nothing but an empty truck, which greatly mystified them until Baushon said to Zuvar:

He was stating that they had lost the trail; that this was the wrong truck. Zuvar agreed, since it was the only

plausible answer. Rejoining men who awaited them, the ugly pair left in their car. Since no one had followed

them along the wrong trail, they did not think in terms of followers, which was a mistake.

This was the right trail, and instead of trailing, The Shadow had simply waited at the end of it for these dupes

to come along. The car that actually followed Baushon and Zuvar was The Shadow's own, with the cloaked

It led to a house not unlike Ardlan's, but in a different, and more antiquated, section of Washington.

WHEN the others left their car, The Shadow did the same, from half a block away. He followed them on foot,

into the rear of the house. A sallowfaced guard conducted them down a flight of steps to the cellar, and

The returning guard failed to see the gliding form that faded into a gloomy corner of the cellar. It was as well

for him that he did not, for The Shadow had drawn an automatic and was ready to sledge it hard to the

Malga was present, with three or four others, among them a woman. She was sleek, catlike, dark of eyes and

hair, the very sort who might figure in schemes of international intrigue. Malga addressed her as Freda, and

After hearing what Baushon and Zuvar had to say, he asked Freda what she thought of it. She replied in the

Freda's opinion was that Baushon and Zuvar had been deliberately tricked. Somewhere along the line,

another truck must have curved in and played a game of crosstag with the first, taking Malga's men off the

friend, The Shadow" he spoke the term "La Ombro" with a sneer may be on watch at Bradwell's. I shall

By then, The Shadow was moving away. He did not go up by the stairs; instead, he worked his way through

the cellar, probing with a tiny flashlight. He found a loose window, wormed up through it, and rolled out to

the ground. From there on, it was an easy circuit to the spot where he had left his car.

A whispered laugh in the darkness presaged new plans in The Shadow's mind: ways whereby he could trap

Sometimes, success could come too soon. In fact, one sort of success might block another that was more

IT was high noon, and the upper waters of the Potomac River were gushing merrily beside the little cabin on

the shore. But Jerry Croft, engaged in scientific research, was too busy to look from the window and enjoy

the scene. He liked the open window only because it cleared the cabin of gas every time he gave the

keeping, showing the various wire combinations. He had already disposed of fifty out of the required seven

"Stay as long as you like," returned Jerry. "The only way I can get this job done is to keep plugging at it."

Smiling, Harry departed. Jerry heard the small coupe pull away, and returned to his task. He figured on

another hour, then a few sandwiches, of which there was a plentiful supply. But Jerry stopped just short of the

He was trying combination fiftyeight. It brought results. Blinking lights stopped; red and blue indicated

acetylene gas, which Jerry was using, and the ether dial tabbed. To his amazement and delight, Jerry realized

He spent a short while longer, proving the result. Then, firmly clamping the top of the machine, he turned off

Never had outdoors seemed more delightful. He could feel a thrill that fought off the everbitter memory of

Bothering with sandwiches was a waste of time, to Jerry. He could not hold back his bubbling enthusiasm.

He wanted to get hold of Harry, to relay word to The Shadow. The only way was to go to Washington.

Grabbing his hat, Jerry put a padlock on the cabin and started along a path that he knew led to a road.

Hitchhiking into town was something of a problem, especially as cars weren't frequent along the Potomac

road. Seeing a service station, that was combined with a small store, Jerry stopped there. He bought a pack of

cigarettes, pocketed the paper matches that came with them. Then he opened conversation with the rather

"Nice place you have here," remarked Jerry. "First time I've been around Riverview Corners. I'm staying at

"Expected a friend out from Washington," resumed Jerry. "Only, he hasn't come. Guess he's forgotten where I

"In that case," suggested the dour man, "you ought to go into town. It's only about an hour."

"By car, yes," agreed Berry. "The trouble is" he gave a troubled smile "my friend is the one who has the

As Jerry spoke, a delivery truck pulled up in front of the store. Its driver was coming in to get cigarettes, and

"Sorry there's no taxi service out here," remarked Jerry, to the storekeeper. "It would be worth a couple of

"Come on, then," the fellow said. "I'll take you up for a couple of bucks. But I'm in a hurry:"

HURRY suited Jerry. They reached Washington under the estimated hour, and Jerry insisted that the delivery

man take an extra dollar. Transferring to a cab, Jerry rode to the hotel where he knew that Harry Vincent had

Of course, Harry had! Jerry should have thought of it before. Harry was staying in the log cabin on the

There was no other way to reach The Shadow. Trying Vic Marquette was totally out of the question. So Jerry

decided that the only thing to do was leave a message for Harry to call him somewhere, in case Harry came

But where should he have Harry call? Debating that question, Jerry suddenly had an answer.

He knew that Anderton had kept confidence with Ardlan, and greatly regretted the professor's death. He

would be glad to know that Jerry had set out to vindicate Ardlan, and had obtained some success. The only

danger, as Jerry saw it, lay in the chance that Bradwell might be at Anderton's.

Finding Bradwell's card, Jerry noted the telephone number, and used the simple expedient of calling the

house. Hearing Bradwell answer, Jerry hung up. Bradwell was not at Anderton's, which was all that Jerry

Riding to Anderton's by cab, Jerry was chuckling over that little stunt, but his laugh ended as he reached the

apartment hotel. The first person he met was Ruth Anderton, who was tripping breezily from the doorway in

Before Jerry could sidestep the girl, she had him by the arm and was gesturing toward a roadster parked by

"You're coming out to Pimlico Racetrack with me!" she exclaimed, saucily. "You can't dodge me this time! I

have a lot to talk about, and I know that you're no longer busy. If you try to get out of it, I'm going to follow

"You promised me a date, and I'm tired of waiting for you to keep it. We'll have dinner when we get back,

She meant it all, as Jerry could tell by the firm expression of her lips. Such persistence could mean trouble,

particularly since Jerry had begun to remember, after calling Bradwell, that various people in Washington,

specifically Malga Co., might be on the lookout for him. They might just happen to he watching Ruth, which

"I'll have to see your father first," suggested Jerry. "You'd better come up, too, just so you can tell him that

Ruth came along, a very confident smile on her face. She was sure that her father would have no objection if

Jerry accompanied her to the races. He had spoken of Jerry and regarded him as a very earnest and capable

young man. Had Ruth known what Jerry really had in mind for her, she wouldn't have been so blithe.

They found Anderton in his study, and Jerry had hardly shaken hands before he gave the reason for his visit.

It was not the one he had originally planned, but a new one, which had struck him on the way up to the

"Mr. Anderton," said Jerry, bluntly, "I want you to prevent your daughter from annoying me any further."

Anderton's long face mingled outrage with amazement, while Ruth gave the most surprised gasp that Jerry

"She kept me away from Ardlan's," persisted Jerry, "twice, when I was needed there. The first time was

excusable; it was the night of the holdup. But the second time, well" he threw a glare at Ruth "her

deliberate falsehood prevented persons from getting to the house in time to save the professor's life!"

It was Anderton who glared at Ruth. Lies were something that he would not tolerate. Knowing it, the girl

"Ruth said that Professor Ardlan was here," he told Anderton, "when he happened to be at his home. It was a

Brazenly, Ruth tried to climb out of it, by matching one falsehood with another, which proved riskier than

"Ask Raymond," suggested Jerry, by way of interruption. "He was the person involved."

ANDERTON stepped out to question the secretary, while Jerry watched Ruth wilt into a chair. She hadn't

supposed that Jerry would press the case so far, and if Raymond talked, disaster would be sure.

In fact, when he saw Ruth's horrified collapse, Jerry was almost sorry for her, particularly when her father

came striding back. The purple hue of Anderton's face told that Raymond had confessed.

"Go to your room!" stormed Anderton, confronting his daughter. "I'll attend to your case later."

"You are going to bed!" roared Anderton. "To stay there until tomorrow! If you need any further persuasion

He was fumbling in the desk for a ruler, and Ruth, fearing more forcible chastisement, went flinging from the

room, with her father calling after her that he was giving her just ten minutes to get to bed.

As soon as the girl was gone, Anderton picked up her car keys, which were lying on the desk where Ruth had

"You can do me a favor," he said to Jerry, "by putting the car away. In fact, you can use it for the next few

days, if you wish. The best punishment for Ruth will be to deny her the car, which will keep her from

"Save your sympathy for Raymond," interposed Anderton. "He thinks he's going to lose his job, but he won't.

Going out, Jerry stopped at Raymond's desk to give the secretary some encouragement. Then, realizing that

"If Congressman Anderton wants to see me, I'll be at the World Wide Cafe at seven o'clock. You can call me

Outside, another car had pulled up in back of Ruth's roadster. It was Bradwell's limousine, and Jerry noticed

Thinking that Winstle hadn't spied him, Jerry slid into Ruth's roadster and started the motor.

It happened that Winstle's book was a vocabulary of Esperanto; he was memorizing certain words, then

looking up from the book while he repeated them. In one of those glances, Winstle observed Jerry in the

Really fearful of her father's further wrath, Ruth hadn't lost a moment in obeying his mandate. She'd gotten to

bed in so few minutes, that she, herself, was really surprised. Then, knowing that she had found refuge, she

Hoping that she could wheedle her father into letting her return to circulation, Ruth remembered the car as a

possible argument, so she went to the window to see if she had luckily placed it where she could later call

The car was in sight, all right, but no longer an argument. Ruth gave an angry gasp when she saw Jerry at the

Her last hope spiked, Ruth glared angrily at the sunlight, wishing that she had gone to Pimlico without

inviting Jerry. She should have taken it as a lesson to mind her own business, but she didn't. She hated the

bright afternoon, but couldn't be glad when it ended, because she was to miss an evening at the Club Fiesta,

She detested Jerry and her father, and felt that she should despise everyone in sight; so she was applying the

rule to Winstle, when she saw the chauffeur leave the limousine and come into the apartment hotel.

Perhaps Winstle had come to take her father to Bradwell's. Ruth decided to find out, as it might prove

Having at least four minutes left, she stole from her room, went along the hall and peeked into the reception

"Mr. Bradwell does," Winstle replied. "You don't know where Mr. Croft has gone?"

HEARING the door of the study open, Ruth scampered back to her room and was in bed, appearing quite

not only listened patiently, but inserted a few sobs. The tearful attitude didn't deceive Anderton; he was no

So was Winstle. Back in the limousine, the chauffeur drove a few blocks, stopped at a telephone pay station

and made a call. He mentioned Jerry by name; then spoke hesitatingly in Esperanto, referring to his little

be at the cafe at seven o'clock, Winstle added a few lame sentences as to how and where he had picked up the

He listened to Malga's reply; remembering the words he didn't fully understand, Winstle looked them up in

Malga had commended him, and given some new instructions. Having received the day off, with Bradwell's

approval, Winstle had made himself very useful. However, the chauffeur considered himself smart, rather

than lucky, in having sopped at Anderton's on the chance of spotting Jerry Croft.

He didn't know, of course, that Jerry's chance fixing of Ardlan's Neutralizer had brought it all about.

Nor did The Shadow, when he stopped at Anderton's a short while later. The congressman had gone out, and

not seeing Ruth's car, the visitor supposed that the girl had gone somewhere, too. Only Raymond was in the

To have mentioned Jerry's visit would have been to bring up something that Raymond wanted to forget. He

still looked worried, and The Shadow took it that Raymond feared his deception of the other day might

Actually, Raymond was troubled because the storm had already broken. He didn't care to gloat over the

deserved discipline that Ruth had received, because he feared that his job was still hanging in the balance.

So The Shadow left Anderton's without learning of the recent tempest, wherein Jerry had temporarily solved

the minor problem of Ruth, only to produce much greater difficulties, which could produce a permanent

Crossed circumstances, loose links in an important chain, were threatening to ruin The Shadow's plans

TWISTED in the Washington traffic, Jerry Croft pulled the roadster to a space beside the curb and paused to

Back to the cabin on the Potomac seemed foolish, for his work was done there, and Harry Vincent probably

wouldn't return for a while. No use in going back to the hotel from which Harry had checked out.

Driving around the boulevards of the capital to look for Harry's car would be even more foolish, for Jerry

realized only too well that he, himself, might be the object of a search conducted by Malga, Baushon, Zuvar,

He thought of driving out to Pimlico, but felt it foolish to waste time at the races. It would be nice to leave

some stubs of racing tickets in the car, for Ruth to find when her father again allowed her to use the roadster;

Jerry didn't feel vindictive; he considered Ruth's punishment sufficiently severe, and was interested chiefly in

the fact that she wouldn't be able to bother him until his present work was through, at which time he intended

Beside, having recognized Ruth's shallow flippancy, Jerry knew that she would misinterpret anything that

showed the slightest thought concerning her. Probably she would regard the ticket stubs as a billetdoux,

Reflecting, Jerry lighted one of the cigarettes that he had bought out at the Corners. He was dropping the pack

Maybe the chauffeur had seen Jerry outside Anderton's. If so, the word had certainly been passed along.

Malga and his tribe would already know that Jerry was in town, probably with something important on his

Bradwell certainly wouldn't have wanted men, like Malga, hanging around his pretentious home by day.

Amid the scene where crime was hatched, Bradwell's would be an oasis. Say, better, a spider's web, with

Spiders liked flies, but not such challengers as bumblebees, and Jerry, knowing all he did, felt that he could

The right stunt was a trip to Bradwell's, to see the millionaire and tell him off for the crook he really was.

Jerry was sure that he could deliver a verbal broadside strong enough to leave Bradwell flabbergasted for a

while to come, but he'd confine it to criticism of such unethical practices as having Professor Ardlan

murdered by undercover specialists under the leadership of a dirty spy, named Kurd Malga.

He'd leave Bradwell shivering in his oversized boots, but without any idea that Ardlan's Neutralizer was

At least, such was Jerry's intent. He didn't realize that he'd be putting himself in the position of a tightrope

walker on a high wire. He was more interested in getting to Bradwell's. He had the address, but how to drive

Jerry figured that a dizzy dame like Ruth Anderton wouldn't be able to find her way around Washington

without a street map; though, at that, she'd probably have to ask someone to interpret it for her.

Anyway, the map ought to be in the car, somewhere; and it was. Jerry found it in a compartment among sortie

LOCATING his present whereabouts, Jerry zigzagged for Bradwell's, getting off streets and onto avenues,

then back and forth again, until he finally pulled into the driveway of a very imposing mansion that had

The driveway split, and one portion went around the great brick mansion, so Jerry took that route.

As he parked the car, he noted a garage, large enough for three or four cars, well to the rear of the house; it

had a driveway leading to another street, which Jerry remembered for future reference.

Ringing the bell of a rear door, Jerry was answered by a dumblooking footman, who seemed shocked

because any visitor could have arrived by the rather private door. When Jerry asked to see Bradwell, the man

shook his head, so Jerry, figuring him a fellow too dumb to be a member of the spy ring, simply pushed him

Another horrified servant rushed up to stop him, and in the commotion, a squeaky voice from upstairs

demanded to know what was the matter. Dodging between the blundering servant and a large grandfather's

clock, Jerry saw a pale man at the top of the stairs. The fellow looked frail and studious, so Jerry reasoned

Without more ado, Jerry dashed upstairs coming upon the squeaky secretary as he was about to dart back to

Sweeping the fellow aside, Jerry opened the door himself and strode into an office, where Rufus Bradwell

was rising from behind a desk, holding a sheaf of letters which he had taken from a drawer.

For a moment, Bradwell's eyes showed glitter; then his squarish features took on their habitual smile. With

his free hand, Bradwell waved the timid secretary back from the door and studied Jerry. To the visitor's

"So it's you," chuckled Bradwell, a raspy note in his deep tone. "Tell me, have you already given up your idea

"What makes you think I had that idea?" snapped Jerry, suddenly on the defensive. "The Neutralizer went to

"Of course," agreed Bradwell, "along with some tanks of gas which would be very useful for experimental

Jerry doubted that Bradwell had. He was quite sure that the millionaire had obtained his information from

Malga, after the latter's bloodhounds had lost the trail through Vincent's trick of taking the coupe from the

truck. While Jerry was groping for a logical reply, Bradwell made the most of the start that he had gained.

"Your intention was quite plain," he told Jerry. "You refused my offer of a job, because you wanted to

With that blunt query, Jerry thrust forward, intending to clear the desk and get at Bradwell if the grizzled man

made a denial. The back step that Bradwell took made him appear fearful and defenseless, but he was neither.

With the jerk, Bradwell let go of the letters he had taken from the desk drawer. Spilling away, the sheets of

Jerry stopped abruptly, for Bradwell, with the desk as barrier, had him quite at his mercy.

"Your impetuous entry gave you away," sneered Bradwell, "so I was properly prepared. Murder is a harsh

Raising his sharp eyes a trifle, Bradwell saw the secretary peering through the doorway, and ordered:

THE two servants came up from the ground floor, with a third to boot. While they were binding Jerry's hands

and feet, Bradwell approached the chair where the young man had been thrust, and demanded:

"So?" Bradwell turned to Peterton. "I think you had better search Croft's pockets."

Peterton searched them, while Jerry was being gagged. Bradwell told the servants to put the prisoner in the

wine cellar, and while they were lugging him away, Jerry turned his head to glare back. He was quite sure

It was three o'clock, for Jerry could hear the grandfather's clock striking, and every hour that Bradwell wasted

would simply bring closer the time when Harry would learn that Jerry was gone, and inform The Shadow.

But Bradwell wasn't wasting time. Viewing the exhibits from Jerry's pockets, he came upon one that pleased

him. It was the pack of paper matches that Jerry had received with the cigarettes. Its printed advertisement

Bradwell summoned Peterton and asked him if Winstle had telephoned lately. Winstle hadn't, so Bradwell

"I shall take the sedan, Peterton. Arrange to have dinner held until eight o'clock, because I shall not return

In the basement, in the dank darkness of the wine cellar, Jerry was getting very well cooled. He was sure that

he heard a car go out from the drive, but supposed that it was Ruth's and that Bradwell was having someone

From then on, Jerry heard nothing except the regular quarterhour chimes from the grandfather's clock on the

floor above. Occasionally, he strove against his bonds, but the cords were too stout, too tight, and too many.

At times, Jerry compared his present plight with Ruth's. She was probably moping because she had been put

to bed, and fuming at the sunlight from her windows, hating the day because it was so glorious. If so, she

Jerry wished that he could get just the most trifling gleam of sunlight, and with the cutting bonds and the

Perhaps the quarterhours should have seemed shorter; but, as they paraded, they seemed longer apart.

Hearing a halfhour chime, Jerry suddenly remembered that the hour before it had been six. His mind flashed

ahead to seven o'clock. If he could only call the World Wide Cafe, somehow, and leave a message there on

To get to a telephone, he would have to escape, so Jerry made another effort at the bonds. For the first time,

he rolled about, and in so doing lost his balance. Shoulder first, Jerry struck a thin post in the dark; one that

There was a clatter; a bottle fell from its perch and smashed on the stone floor beside the prisoner. A wine

bottle, as Jerry could tell from the smell of its splashed contents; but Jerry, though thirsty, didn't care about

the loss of the beverage. Rolling over, he groped with his pinned hands and found a chunk of glass. With its

He had luck. The piece of glass was long and jagged, as good as any knife, as proven by the cuts that Jerry

gave himself. He had severed one rope in a few minutes, and the result gave him enough slack to get at the

Soon, Jerry was ungagged, and carving at the ropes that bound his ankles. Another chime from above told

GROPING, Jerry found a stairway and followed it to the top. He came upon a door, that gave outward several

inches, showing a hasp and padlock on the other side. Dim light from a kitchen entry showed Jerry's wrists.

At first, he thought that they were gory from the cuts, until he observed that wine, not blood, was largely

Gathering himself, Jerry struck the door shoulder first, right by the padlock, hurling all his weight at what he

hoped would be a weak spot. It was. The padlock gave, but the hasp broke and the door flung outward, taking

He heard a startled shout from the kitchen; was on the point of turning back to the wine cellar to get a bottle

as a weapon, when a door came open and one of Bradwell's servants confronted him.

Jerry went at the fellow, this time with punches. He had boxed while in college, and had a very short, neat

uppercut which he used, hoping it would be easy on his fist. It was, but for the first time, Jerry saw what that

The servant was on the floor, while Jerry was still looking for him, which was very good, considering that

another man was springing in through the kitchen. The second servant thought himself a bit of a fighter, but

Jerry got past his guard and jerked his chin with the same neat poke. It sagged this one as it had the first.

On the way out, Jerry ran into the liveried footman who had first admitted him, and flattened the lethargic

fellow before he had a chance to resist. But Peterton, in the hallway, wasn't to be taken by surprise.

He came bounding in, swinging one of Bradwell's canes, which, in other hands, would have been an effective

weapon. Jerry managed to ward off Peterton's swings and grip the fellow's arm. Then, as the secretary's pale

face came about, Jerry tried his one reliable punch, using the other hand for a change.

The way Peterton shut his eyes and wagged his head, was ludicrous. Letting him sag to the floor, Jerry went

out by the rear door, saw Ruth's car where he had left it, and sprang to the wheel.

The key was still in the ignition, for in his earlier hurry to meet Bradwell, Jerry hadn't bothered to remove it.

At this moment, Jerry's recollection of a car that departed earlier seemed so long ago, that he didn't waste

He wanted to be away before Peterton and the servants rallied from the knockout punches he had given them.

Combined, they would be formidable, and on guard against further uppercuts. So Jerry sped the roadster out

It was dark along the streets, and Jerry knew that Harry was probably getting back to the Potomac cabin. But

the only way to reach him was to go there, himself, which would mean a long delay before getting word to

Something would have to be done sooner, in order to trap Bradwell before the millionaire learned that Jerry

Almost seven o'clock, the hour when Jerry had said that he would be at the World Wide Cafe. Perhaps

Congressman Anderton would phone there, or even stop by. At least, Anderton would listen to Jerry's story,

and probably believe it when he heard how Jerry had wasted an entire afternoon in Bradwell's wine cellar,

It was worth the chance, so Jerry, picking streets as best he could, drove for the World Wide Cafe in hope

that he could start the law's machinery working toward trapping Bradwell, Malga, and the rest a task which

THE same darkness that shrouded Jerry's flight from Bradwell's was furnishing cover for stealthy figures that

approached the old house which harbored Malga's headquarters. But slinky though those figures moved, they

No more were present than at the previous meeting; in fact, the total numbered less. Freda was present, and

so were several others, but such standbys as Baushon and Zuvar had not yet arrived.

It made The Shadow's position rather precarious, since newcomers might appear at any moment from the

stairs behind him. Nevertheless, this was the situation that he wanted. His purpose was to learn as much as

It was nearly seven o'clock, and from Malga's glances at a watch, The Shadow decided that seven was to be

the zero hour. An odd fact, considering that many members of the clan were still absent, and that Malga's

search for Ardlan's missing invention could scarcely have carried to the cabin on the Potomac where The

That brief delay gave The Shadow a chance to consider why Jerry happened to be in Washington. He must

have come of his own volition, since he was still at large, according to Malga's statement. There could only

be one logical answer, and it flashed to The Shadow's mind just as Malga resumed.

"Once we have captured Croft," declared Malga, "we can persuade him to tell us where the machine is

The words proved that spies had not found the Potomac cabin; also, that Malga had no idea that Jerry had

already started to put the Neutralizer into condition. In fact, from his contemptuous tone, Malga had seemed

Malga was reaching for the telephone, and it buzzed as he picked it up. Answering, he listened a few

He wanted the caller to speak more clearly, which indicated to The Shadow that Winstle was on the line.

Such proved to be the case. After Malga received the report, he ordered the caller to come to headquarters;

They could tell that Malga had received unusual news. He gave the details; his speech, as The Shadow

Hearing creaks from the stairs behind him, he glided away from the door and was in darkness, when two

newcomers passed. After they entered the meeting room, The Shadow returned to the door and picked up the

"So we shall go first to Bradwell's," Malga was saying, "and be prepared for whatever may happen when he

returns. No need to wait for the others. Winstle can stay outside and tell them where to go. As for Croft, we

"Winstle tells me that Croft is quite infatuated with Ruth Anderton," declared Malga. "They are such friends,

that she lent him her car this afternoon, probably because she was going elsewhere with her father. You have

"Not yet," he said. "I shall first call the Anderton apartment, to make sure that the girl had not returned there."

There was no answer to the call, and as that became apparent, Malga's teeth showed wider in his lipless smile.

Meanwhile, The Shadow was considering this new factor, and from it, he knew that Winstle must have

slipped badly on one point. No love existed, or was lost, between Jerry Croft and Ruth Anderton certainly

It made the matter of a car something of a riddle, even to The Shadow, though he felt quite sure that

Anderton, rather than his daughter, must have been the one who supplied it to Jerry.

"Tell Croft you have been captured. Coax him to the other headquarters, where we are going later. It is a

The World Wide Cafe was on the line. Freda asked for Jerry. Hearing his voice, she spoke in the dulcet but

affected tone of Ruth Anderton a perfect imitation, albeit Freda added a touch of breathless, repressed

This time, The Shadow's slide to cover was necessary for two reasons. Newcomers were not only coming

down the stairs; Malga's larger crowd was moving from the meeting room. Supplying the new arrivals with

bombs, Malga told them to come along. The whole tribe, Freda included, went up the stairs.

THE last footsteps had scarcely dwindled before The Shadow was in the meeting room, where Malga had left

a light burning. A better view of the arsenal showed him that the departers had taken other weapons than the

Picking up the telephone, The Shadow called the F.B.I. and, in Cranston's tone, asked for Vic Marquette.

But it was the voice of The Shadow that Vic heard, when he spoke over the wire. Instantly, Vic was agog.

Small wonder. The Shadow was telling Marquette that Malga and the ring of international agents had two

strongholds: one in Washington, the other outside. The Shadow named them: one, the house where he was at

"Get men to both places," said The Shadow, "and be careful at the inn, because guards are hidden just inside

the gates. Croft is starting from the World Wide Cafe. Flag him on the way. He thinks Ruth Anderton is a

side of the house. Be careful, in case some of Malga's men happen to be there. Check on a possible guard on

Finishing the call, The Shadow paused to listen; then called another number. He spoke to his contact man,

He gave Burbank instructions, to be relayed to the Washington police shortly before eight o'clock. Then,

learning that Burbank had a report from Harry Vincent, The Shadow waited to hear it.

Harry had gone back to the cabin, to find that Jerry had left. Moreover, the door was broken open and the

Neutralizer had been stolen. There were tire tracks of a large car close to the cabin. Other details, which

With that, The Shadow slid the receiver on its hook, but shifted his body to hide the action. At the same time,

"Bonega, Malga!" said The Shadow. "Mi helpos vin. Nur malsagulo pensis ke La Ombro estas amiko de la

"Excellent, Malga! I shall help you. Only a fool thinks that The Shadow is friendly to the law!"

There were slight sounds indicating that The Shadow was handling the telephone. In fact, one of his hands

held an object upright; the other, something toward his ear. Those hands had come from beneath The

Shadow's cloak. Instead of the telephone and its receiver, he was gripping a brace of automatics.

The Shadow's position resembled that of Hortland, the man whom he had once trapped. Creeping sounds

proved that intruders were moving up behind him. But instead of sending, or even pretending to send, a call

He was faking a call to Malga, the chief these arrivals recognized, using the language that the spy ring had

It had made his enemies hesitate; made them hold back the death thrusts that would have struck, had they not

caught those words in the tongue they understood. Yet The Shadow knew that he was carrying their credulity

to the limit; that this game could be quickly overdone. Doubt would follow swiftly.

FLINGING upward, backward from the table, he swept his arms wide as he spun about. One man, he was

It was Baushon; he didn't duck his bulgy head in time. The Shadow's right fist, weighted by the gun, flattened

At the same instant, The Shadow's left hand, diving under his right arm, stabbed a shot to the rear. It was

meant for a man on The Shadow's left, and it skimmed Baushon's teammate, Zuvar. The spurt of the .45 made

A knife clattered from Baushon's downdriving fist, as the bulgeheaded man hit the floor. Another blade,

tossed by Zuvar's darkish hand, barely missed The Shadow. Zuvar's dive was the reason for the wideness of

Instead of settling the pair, The Shadow made a lunge for the door to meet the guard from the floor above. He

had followed Baushon and Zuvar to the cellar and was aiming for The Shadow with a sawedoff shotgun.

Beating him to the shot could hardly suffice, for The Shadow knew the deadly spray of sawedoff shotguns

at close range. With an automatic, he bashed the shotgun downward; when the short barrel blasted, its load

On their feet, Baushon and Zuvar sprang for the shelves, while The Shadow was wresting the shotgun from

the guard. Another man came dashing into the meeting room as The Shadow and his grappling opponent

The new man was Winstle; seeing that Baushon and Zuvar were snatching bombs from a nearer shelf, he

Knowing that they couldn't gas The Shadow while they, too, were still in the meeting room, Baushon and

Zuvar fled, with Winstle dashing ahead of them. Outside the room, Baushon and Zuvar turned to hurl the

A mocking laugh greeted them; they saw The Shadow almost upon them. He had slugged the guard; and had

For The Shadow wasn't anxious that a gasfilled "pineapple" should be dropped in the cramped confines of

the meeting room while he still was there. Either by accident, or through sheer desperation, one or the other

With the stairs ahead of them, and Winstle halfway up, Baushon and Zuvar decided upon flight. On the steps,

however, they turned again to fling their bombs, for they were above the danger level.

The Shadow stopped those throws with bullets. His shots, his only way of saving his own life, clipped both

his foemen and brought them bounding to the bottom of the stairs. The dropping gas bombs burst, with

clouds of purplish smoke engulfing the pair and rolling upon The Shadow like a monstrous, clutching flow.

Deadly stuff, that gas, which was getting its preview earlier than Malga had planned. It snuffed the lives of

From the top of the stairs, Winstle saw the spreading puffs and knew that the two spies were doomed. On the

chance that the gas hadn't reached The Shadow, Winstle flung his bomb deep into the spreading cloud.

The thing he threw exploded. Its blast rattled the cellar, but didn't damage the meeting room; otherwise, the

whole house would have gone up in gas and flame. The explosive bomb cleared the smoke away and showed

the open floor. Winstle gave a very ugly gloat. He was sure that he had finished the career of The Shadow.

Hustling out by the ground floor, the only way he knew about, Winstle reached the limousine in front of the

house. He couldn't afford to be seen in this vicinity, and he had no reason to wait around. The reserves that he

Safely from the neighborhood, Winstle looked in the car mirror to make sure he wasn't being followed. The

back seat of the big limousine was dark, very dark. Too dark, in fact, for Winstle couldn't even see the rear

Winstle was halting at a traffic light, wondering why his eyes deceived him. Before he could guess, blackness

A fierce laugh whispered in the chauffeur's ear as he succumbed under the pressure of blackgloved hands

Hidden by the cloud of deadly gas, The Shadow had reached his cellar window before Winstle flung the

explosive bomb. Waiting in the limousine, he had allowed Winstle to drive off. Also clear of the territory to

which he had summoned the Feds, The Shadow was taking over the limousine, and Winstle with it.

MALGA'S call to Anderton's apartment had not been answered, but it was not proof that no one was at home.

She was in bed, with the lights out, another of her father's orders. He wanted her to see how pretty the bright

glow of Washington was, when viewed from her window and not from the interior of a night club. After ten

minutes or more, the telephone bell began to ring again. This time, Ruth was quite sure of an earlier guess:

that she was the only person in the apartment. Her father was out, and Raymond had gone home, but Ruth

was worrying about Martha, the portly housekeeper, who still should have been around.

Evidently Martha thought that Ruth was asleep, so had gone out a while herself, which was exactly what

Ruth had hoped would happen. Of course, Martha had first locked all the bureau drawers and the closet, a

All of Ruth's clothes had first been put away; at least, all that Martha knew about. But there were others, in an

Stealing out, Ruth found that Martha had not locked the linen closet. She opened the trunk and brought out

The trunk contained everything that Ruth needed, even a pair of old evening slippers. Rapidly, she dressed,

hoping that she could still keep what she regarded as a seveno'clock date with Jerry.

In Raymond's desk, Ruth found a few dollars in stamp money, took the cash along, and hailed a cab as soon

Had Jerry Croft really cared a jot about Ruth Anderton, he wouldn't have been at the World Wide Cafe when

she arrived there. Even without caring, he might not have stayed if he had trusted the facetious girl.

Jerry had fallen perfectly for Freda's bluff; he really thought that he had listened to Ruth over the telephone.

In Jerry's opinion, Ruth's call was a hoax. Learning where he was, the girl had probably tried to square

accounts by sending him on a wildgoose chase out to the Arromac Inn. Maybe she figured that he would get

So Jerry had resumed his dinner, still hoping that Congressman Anderton might appear. In that case, Jerry

would suggest a trip back to the apartment, just to make sure that Ruth was still there.

However, Anderton didn't appear, and Jerry began to wonder how he could explain things if Ruth really had

been abducted. After all, it would have been true to form for her to get out of bed and leave the house against

her father's order. In that case, she really could have been grabbed by some of Malga's crowd.

The thing worried Jerry, so he went to a phone booth, when he finished dinner, and called the Anderton

There was no answer. Jerry came from the booth, very worried, and was stepping to the check room to get his

SHE wasn't as nattily dressed as usual, and her hat looked too sensible to be of recent style. But those points

made no dent on Jerry. All he noticed was the way Ruth greeted him, as though she had worked a very clever

"I'm famished," announced Ruth. "All I had for dinner was crackers and milk. Let's have a real dinner."

"At the Arromac Inn?" laughed Ruth. "Why, it's a horrible place! If I ever told anyone that I'd been there, I

She put it so snippily, that Jerry gave the statement an extra significance. He thought that Ruth was politely

admitting her part in the hoax, but brazenly expecting him to accept such a thing as part of her special

privilege. In her turn, Ruth didn't like Jerry's glower. She decided to be smart too smart.

"You thought I'd stay where I was put," scoffed Ruth. "Didn't you? Well, I didn't! I'm here, so what are you

She lifted her face to look at Jerry. Her eyes were defiant, her nose snippy, her lips too smartly confident in

their tight smile. The thrust of her chin showed that she expected something. She was asking for it, so Jerry

Ruth had curled halfway to the floor before Jerry scooped her to her feet and held her there. No one else had

witnessed the delivery of that farewell token. Beckoning to the head waiter, Jerry gained his aid in getting the

"Congressman Anderton's daughter," confided Jerry. "She shouldn't have come out tonight. I don't think she's

well, because she's supposed to be in bed. Looks like she's fainted. You'd better send her home in a cab."

The head waiter agreed. They put Ruth in a cab, and one of the hatcheck girls was deputized to accompany

her. The cab had gone and Jerry was turning back into the restaurant, when a firm hand clamped his arm.

"She didn't call you," interposed Vic. He hadn't seen Ruth's departure in the cab. "Someone else did. What I'd

"Rufus Bradwell!" exclaimed Jerry. "He's in back of everything! He even bribed Malga and the spy ring to go

"I got those this afternoon," he said, grimly, "while I was tied up in Bradwell's cellar. That's where he put me,

They got into Ruth's car and Jerry took the wheel, while the Fed pointed out the shortest route to Bradwell's.

It led past the apartment hotel where Anderton lived, and Jerry smiled as he noticed the cab out front, and

looked up to see a light in Ruth's window. He hoped that she hadn't gotten over her surprise.

In fact, Ruth hadn't. Martha was back, and the helpful housekeeper had undressed Ruth and put her into bed

again, where the girl was just beginning to wake up. Ruth could not understand why Martha was chiding her,

Ruth couldn't remember having gone out. She felt sleepy, and she recalled a bad dream wherein a mule had

kicked her in the jaw, so heavily that it still ached. She asked Martha if it was after seven o'clock, and when

the housekeeper said yes, Ruth decided to go to sleep again and forget everything, including Jerry.

MEANWHILE, the sporty roadster was approaching Bradwell's. Hearing more of Jerry's story, and deciding

that it meant something, Marquette decided that a car that showed so well at night was not the proper medium

of approach. Jerry mentioned the rear route to Bradwell's garage, and Vic considered it.

"We'll stop on the back street," the Fed decided, "and go the rest of the way on foot. I think we can handle

this alone, Croft. The available men have gone out on other jobs that I'll tell you about, later."

It sounded good to Jerry. When Vic asked if he had a gun, Jerry shook his head. He had left the revolver out

at the Potomac cabin. So Vic produced a spare automatic, showed Jerry where the safety catch was, and told

From the moment that they started their creep in through the rear drive, Jerry sensed danger. There was much

shrubbery around Bradwell's, and each bush looked as if it hid a man. Fortunately, the drive was very dark,

A car swung in through the rear drive. It was Bradwell returning. Ducking around the front of the garage, Vic

automatic device. At the same time, the lights within the garage came on, and Vic, nudging Jerry, told him to

Moreover, The Shadow was in a fixed position, that he could not alter while still in the limousine. But it

wasn't danger to himself that brought him from the big car, on the side toward the garage. Other men, who

didn't know the deadliness of weapons being used against them, were in serious plight.

Vic, Jerry, and even Bradwell, the man they had forgotten, were shooting wildly, hopelessly, at foemen they

could not see. When a big bulb smashed beside them and sent up its cloudy, purplish ghost, they didn't realize

Vic first, then Jerry, went reeling into the garage under The Shadow's shoves. Grabbing Bradwell, The

Guns were talking now, outside, shattering the windows in the garage door, above the level of the defenders.

Those shots seemed foolish, until their purpose became plain. A bomb came through the space where glass

Shying from it, Vic, Jerry and their companion, Bradwell, went in the direction of The Shadow's call. He was

Shouting for them to stop, Malga ordered a few picked men to put on special gas masks, the only sort

effective against the new supergas that the murderers had used. Peering through the window of his own mask,

the chief killer yanked open the garage door and led his chosen squad into the preserves of death.

They were groping through the heavy curtain of purple, when Malga halted, frozen with amazement.

From the midst of that deadly mass in fact, from the very center came the challenge of the amazing

A waver of wind dwindled the purple veil. Around the sedan Malga saw a sphere of clear air, an isle of

safety, in the very midst of a deadly sea. Blinking through the goggly window of the mask, Malga couldn't

understand until he heard a hum, to the accompaniment of whirs, that dispelled the silence of the clearing

The tones came from a strange machine that was in Bradwell's sedan. Strange to some who saw it for the first

time, but not to Kurd Malga. The device was the famous Neutralizer, the legacy of Professor Ardlan, a

bequest that was saving the lives of men who were threatened by the very murderers of the old inventor!

It was the Neutralizer, operating as Ardlan had known it could and had intended that it should!

There was the slightest of smiles on the lips of Cranston. The Shadow had analyzed these facts long before.

He had found the real crux early: why should Malga, anxious to destroy Ardlan's invention, have dallied as

The answer was that Malga had preferred to let Bradwell try a while. He had supplemented the Crumpf

failure through Trennick, another worker who had been drawn into the spy ring. Later, Malga had made a

thrust himself, the night when he had murdered Ardlan. Even then, he had tried to keep the finger pointing to

Bradwell. A master of undercover work, Kurd Malga preferred to keep his own tracks hidden.

Things clicked suddenly to Jerry Croft. He should have realized, from the comparatively easy treatment he

had received this afternoon, that Bradwell wasn't behind the game. The case was plain: Bradwell, who simply

wanted to acquire the Neutralizer and bring it out as something new, was very minor when compared to the

The Shadow had seen all that before, from the obvious indications. He had surmised that Jerry's trip back to

Washington today could only mean that the Neutralizer was working, and that Bradwell, going out to seize it,

would be against Bradwell, who had gotten possession of the Neutralizer, The Shadow had seen a sure way

your own life, and some others, besides. By the way" Vic paused, to look at the device with the tanks and

lights, which was standing on a table in the corner "do you still claim a share in this invention, Bradwell?"

"I suppose you'll have no charges, then," said Vic to Jerry. "We've got the man we wanted, the real king of

the game, Kurd Malga. You can give the Neutralizer to the government, just as Professor Ardlan wanted."

"With your permission, Croft," boomed Congressman Anderton, "I shall attend to that part."

With a smile, Jerry agreed. He knew that Anderton attended to things well, as he had done in Ruth's case. But

In the case of the Neutralizer, Jerry was thinking what a mess of hopeless junk it would be at present, if The

Esperanto, the artificial language which appears in the story, was devised in 1887 by Dr. Ludovic Zamenhof,

of Warsaw, Poland. It was intended as an auxiliary tongue for international use, and its name, in the

Esperanto language itself, means "One Who Hopes." That the hopes of Dr. Zamenhof have been fulfilled is

proven by the fact that Esperanto is, today, in use throughout the world as a common mean of correspondence

Though Esperanto has not replaced existing languages, it should be remembered that such was not the intent

of its originator. Its widespread usage, rather than any localized adoption of the tongue, is largely in keeping

The prime advantages of Esperanto are its simplicity and its regularity. It is not, as many persons erroneously

suppose, a conglomeration of many languages, but rather a language of its own, incorporating the best

features of other tongues, and wherever possible, the word roots common to most. From there on, Esperanto

includes many helpful points specially invented for its own development, all to the advantage of its users.

Similar to the English alphabet, that of Esperanto modifies certain letters with accents, as a guide to

pronunciation. Some letters take uncommon pronunciations, notably the letter "j," which is pronounced more

like "y" or, specifically, like "j" in the word "hallelujah." However, once the pronunciations are acquired,

they are highly useful, because all words are pronounced as spelled, with accent always on the next to last

syllable. Thus, once learned as a written language, Esperanto can easily be acquired as a spoken tongue.

The definite article "the" is la. There is no indefinite article "a." From there on, the forms of speech take

regular rules. All nouns, or substantives, end in "o," as domo, a house; pomo, an apple. For plurals, "j" is

added (pronounced "y") making houses, domoj; apples, pomoj. Adjectives end in "a," as bona, good; granda,

With adjectives, we observe the effective simplicity of Esperanto. The prefix mal is used to denote an exact

opposite. Thus: malbona means bad; malgranda, small. For comparatives the word pli (pronounced plee)

signifies more; while most is plej (pronounced plehy). Thus, from bona, good, are obtained: pli bona, better;

Verbs are no problem in Esperanto. An example shows why. From the verb paroli, meaning "to speak," we

gain the following forms, by dropping the final letter "i." Paroles signifies "am speaking"; parolis, "spoke" or

"did speak"; parolos, "will speak." The conditional "should speak" is paroles; while the imperative "Speak!"

is parolu! Other verb forms follow similarly established rules, without any troublesome exceptions.

Adverbs end in "e." Thus, corresponding with rapida, quick, we find rapide, meaning quickly; likewise, bona,

good, is paralleled by bone, meaning well. Pronouns, such as I, mi; you, vi; he, li; we, ni; they, ili, are

regularly formed, and simply add "a" to denote possessives, as: mia, my; via, yours, etc.

One feature of Esperanto which has been unsoundly criticized, is its use of the accusative, or special form to

denote the object of a verb. Thus, to say: "I saw the dog," would be "Mi vidis la hundon," the letter "n" being

The reason for this is that it allows for any arrangement of the sentence, thus enabling persons whose own

languages have peculiarities to understand each other in Esperanto. The sentence above given could also be

phrased: "Mi la hundon vidis," or even "La hundon vidis mi"; yet in every case it would be plain that "I saw

the dog." If "the dog saw me," the words would be "La hundo vidis min," the added "n" for the object being

While not complete, the rules given above cover the fundamentals of Esperanto in considerable measure. But

it should not be assumed therefrom that Esperanto can be acquired without considerable study. If the

language stopped at this point, those learning it would be forced to acquire a tremendous vocabulary of

To offset this; and other problems, the originator added many remarkable short cuts and systems, which,

when once learned, reduce vocabulary to the minimum. These are mostly in the forms of prefixes and

For example: ad symbolizes a continuation. Thus; rido, meaning a "laugh," can be amplified to ridado, for

"laughter." The suffix aj indicates a concrete idea or substance; so from the ovo, "egg," comes ovajo,

meaning "omelet." Thus, Esperanto, in a sense, becomes a language of ideas, in which it is often possible for

a speaker to find the right word for an object even though he does not actually know the word in question!

An interesting illustration of Esperanto word pictures can be cited from the term florbrasiketo, which appears

in the accompanying story, and which means "broccoli." The word floro means flower; brasiko is cabbage; et

is a suffix signifying diminutive or small. Thus, florbrasiko, literally "flowering cabbage" gives the picture of

a "cauliflower," while florbrasiketo gives the same picture, in smaller form, thus indicating "broccoli" to

Similarly, brasiketo, indicating something like a midget cabbage, is obviously a "Brussels sprout." Thus from

two words: floro and brasiko, come five words, which, once learned, cannot be forgotten, because they

There are various textbooks of Esperanto on the market, and one, compact and paper bound, has gone into

editions totaling sixtyfive thousand. Dictionaries of Esperanto are likewise large in scope, but convenient in

Whether or not Esperanto is destined to replace existing languages, and play a strong part in international

good will, as its founder, Dr. Zamenhof, hoped, is still a question. It is certain, however, that its simplicity

and its appeal to the creative sense increase the interest of those who delve into the language, and that
