CHAPTER XV

THE TRAITOR UNMASKED

With his fingers across his lips, Cole enjoined silence. His glance

darted quickly over the floor, the ceiling and the walls. He moved

hither and thither, looking behind desks and filing cases. Finally he

stepped behind Carlin’s desk and gazed speculatively at a panel of

grille work in the wall. He held his hand before it and felt a strong

draft of fresh air. It was obviously a ventilating shaft, and the force

of the current suggested that air was driven into it by fans.

He whirled round and whispered to Carlin and the girl. “Talk,” he said,

“talk on any subject but the one you’re thinking on. Be as natural as

you can.”

Carlin showed plainly that he did not understand, but he nodded

obediently. Cole tiptoed to a typewriter desk in the rear, and in one

of the drawers he found a box containing a number of small tools.

Selecting a screw driver, he went back to the air shaft and loosened

several of the screws that held the grilled panel. In a few moments he

could bend it outward, and now he inserted his hand and ran it up and

down the sides of the shaft.

“Any more of that sauterne left?” he heard Carlin ask the girl.

“About a dozen bottles, I think.”

“We’ll instruct the chef to have it served after the fish course. Just

to celebrate the occasion, you know. Afterward——”

The lawyer ran on with the dogged air of a soldier obeying orders that

he doesn’t understand; but Cole heard no more. A sudden tensing of his

body hinted that he had verified a suspicion. He had found a small

metal disk attached to the opposite side of the air shaft, and to it

was affixed a wire that extended upward. A serio-comic smile twisted

his lips as he rejoined Carlin and Miss Brown. “Guess what I found,” he

said in a whisper.

The other two stared.

“An amplifying disk and a wire that seems to run out on the roof. A

dictaphone in other words. There may be others scattered throughout the

place. My little ruse has shown that these walls have ears.”

The lawyer was too astounded for words. Miss Brown looked fixedly at

Cole, her lips trembling a little at the corners.

“Did I hear you say something about sauterne?” asked Cole in his usual

speaking voice, at the same time motioning them to step farther away

from the shaft in which the disk was hidden. “Favorite drink of mine,

though I take only an occasional drop of such things.” Again he lowered

his voice. “To-night I shall get out on the roof and see where the wire

runs to. Carlin, this is additional proof that there is a renegade

in our midst. The man who posted the hunchback on how to get in here

probably installed the dictaphone. It isn’t safe for us to make a

single move until we have singled him out and rendered him harmless.

We must attend to that even before we consider what is to be done with

the body of Reeves.”

Carlin still seemed a trifle dazed. “You are right, of course,” he

said. “We must get rid of the blackguard at once. It is startling to

think that any one in our organization may be the traitor. How are we

going to find him?”

“Leave that to me.” Cole’s narrowing gaze slanted upward, as if his

thoughts were on the track of an idea. “I have noticed that a man of

that kind nearly always has a flaw in him of some sort. Generally that

flaw is cowardice. That gives us an advantage over him, right at the

start. We’ll play on his cowardice and make him betray himself.”

The lawyer looked somewhat dubious. “How?” he asked.

“I haven’t studied out the details yet,” said Cole, but the slow

twinkle in his eye told that the idea was assuming shape. “You sowed

the seed of a plan in my mind when you mentioned sauterne. But don’t

expect anything spectacular. Sometimes simple measures work best. Can

you arrange to have the whole organization here for dinner?”

The lawyer fingered his chin in a bewildered way. “It could be managed.

Most of them have planned to attend, anyway.”

“Splendid! Now, Carlin, since I am to take charge of the work here,

it would seem only fitting that everybody should drink my health in

sauterne, wouldn’t it?”

“Cer—certainly,” stammered Carlin.

“You could propose the toast yourself. I know you will do it

charmingly. And I want you to see to it that everybody is invited to

drink, including the waiters and the kitchen help. You could explain

that the toast is to be a sort of pledge of allegiance.”

The lawyer looked blinkingly at Cole, searching his face in vain for a

sign that he was jesting.

“I’m not sure there is enough sauterne to go around,” observed Miss

Brown, who evidently shared Carlin’s stupefaction.

“Then use smaller glasses,” suggested Cole. “Besides, in an emergency

the wine can be thinned out. I think you said there were a dozen

bottles. That ought to be enough for one round. I can almost taste

that sauterne already.” He smacked his lips as he consulted his watch.

“Carlin, I wonder if you would mind telephoning my landlady, Gramercy

0099, to see if any messages have been received for me. The bright

youngster who is watching Doctor Latham’s house may have been trying to

reach me. In the meantime, Miss Brown, I am going to ask you to come

with me to the dining room. I want to get a general idea of the seating

arrangement.”

With a long, wondering glance at Cole, the girl conducted him from the

office, while Carlin cleared his husky throat in preparation for the

task assigned him.

“You are a very deep person, Mr. Cole,” the girl observed, as she led

him into the dining room, where tables were set in horseshoe formation.

“I have a suspicion that you are keeping a perfectly gorgeous scheme

all to yourself.”

Cole smiled thinly, while his glance roved over snow-white napery and

brightly polished silver. At times Miss Brown had a naïveté about her

that he found rather alluring.

“I’ll take you into the secret in a few moments,” he promised. “One

confidence deserves another, however. How much longer must I go on

calling you Miss Brown?”

“Don’t you like the name?”

“I do not. I suspect you invented it on the spur of the moment the

other night. It served well enough for a temporary acquaintanceship,

but now its usefulness is past.”

“True,” she admitted. “It was an awkward alias, anyhow. How do you like

Merle Brownell?”

“Much better. One syllable more or less makes a lot of difference at

times. I take it you are the high priestess of The Unknown Seven?”

“Oh, no! I’m only an odd-job expert. My father, who died three years

ago, was the founder of the organization. I have hung around, more

or less, ever since. Most of the time I suspect I am in the way, but

occasionally I manage to make myself useful.”

Cole regarded her with a look that seemed to say, “You’ll pass.”

“You promised to take me into your secret,” she reminded him. “Aren’t

you afraid? How do you know that I’m not the traitor, or traitoress?”

“I know,” said Cole firmly, “but don’t ask me how I know. By the way,

Miss Brownell,” and Cole lowered his voice several octaves, “I see the

wineglasses haven’t been placed yet. Don’t you think you had better

speak to the chef about the sauterne?”

She gave him a puzzled look, then a roguish smile illuminated her

face. “I’m beginning to think the sauterne is the chief ingredient in

that brilliant idea of yours,” she declared, as she left the room. A

few moments later Cole followed, turning toward the laboratory which

Carlin had so proudly shown him. At one wall were several shelves on

which bottles were placed in long rows. After studying the labels, Cole

selected one of the bottles and put it in his pocket.

Miss Brownell was supervising the placing of the wineglasses when he

returned to the dining room. He stood aside and watched silently until

the task was finished and the waiter had left the room. Then he took

the bottle from his pocket and stepped to the table.

“Please guard the door,” he told Miss Brownell, speaking in very low

tones. “If any one wants to enter, keep him out on any pretext you

like.”

She watched him in astonishment while he went to work. The bottle

contained a colorless liquid, and with great care he poured a few drops

into each wineglass.

“Are you going to poison us?” she asked. There was a secretive air

about Cole that seemed to prohibit talking aloud.

“No, the stuff’s harmless. Nothing but spirits of hartshorn. It will

mix with the wine, but only a person with a very sensitive tongue will

notice the queer taste. Such a person, if there should be one among us

this evening, will notice that the wine has an odd flavor, but that’s

all. He won’t be able to identify the added ingredient. The quantity is

too slight.”

“That makes everything very clear of course,” remarked Miss Brownell.

“About as clear as mud.”

Cole went calmly on with his work. “I suppose it has often occurred

to you, Miss Brownell, that the imagination is a great aid to one’s

senses. Tell a person there’s a fire in the next room, and he will

instantly smell smoke, even though he may not have noticed it before.”

“I don’t see what that has to do with what you are doing.”

“A very great deal. When these glasses have been filled with wine, a

person, taking a casual sip of the concoction, will not notice the

queer taste. If he is told, after the second or third sip, that he

has drunk poisoned wine, the peculiar taste will become noticeable at

once. Without stopping to try to identify the queer flavor, he will

instantly become convinced that he has been poisoned, especially if the

circumstances are such that he already has reason to fear that some

such thing is going to happen to him. That’s what imagination does to a

person.”

“Is this some kind of psychological experiment?”

“In a way.” Cole had reached the last glass and was now putting the

bottle in his pocket. “Incidentally it is interesting to note that a

person with an uneasy conscience always has a lively imagination. Not

only can he spot real dangers a mile off, but his guilty conscience

is constantly surrounding him with imaginary ones. It’s a lucky

thing, too. If it wasn’t for such frailties in the human make-up,

we detectives would lose our reputation for achieving brilliant

deductions.”

Miss Brownell smiled soberly as they walked out. “I think we are

going to have a most interesting dinner,” she murmured. “I hope your

psychological experiment will succeed, Mr. Cole. I must run off now and

powder my nose.”

Cole slipped back to the laboratory and replaced the bottle. A few

moments later he met Carlin in the corridor. The lawyer told him that

he had called up Cole’s landlady, but no messages had been received for

him.

“That means Doctor Latham has made no move yet,” said Cole

thoughtfully. “He plays a slow and sure hand.”

The lawyer nodded. “Your landlady seemed quite distracted over the

robbery,” he announced.

“She isn’t the only one. I bet Toots is the most distracted female in

the world, just now.” Cole gazed gloomily into space, and then a tall,

broad-shouldered man approached with an easy swagger. Cole’s lips

twisted into a reminiscent smile, as he recognized the surgeon.

“Hello, Ballinger,” said the lawyer. “Shake hands with Kingdon Cole if

you dare. I wouldn’t blame him if he were to shoot you on sight, but he

has a forgiving disposition. Cole has just agreed to become one of us.”

“Splendid!” ejaculated the doctor, and the two men shook hands. As

their fingers touched, Cole experienced that indescribable something

that comes from contact with a man of strong personal magnetism.

Ballinger’s grip could not have been called energetic, but it

transmitted a subtle electric current.

“You are tackling a man-size job,” remarked the doctor after Carlin

had withdrawn. “You will have a chance to match your wits against the

infernal cleverness of the astutest rogue in the country. I suppose

Carlin has explained the situation to you?”

“He has only given me a few hints. There hasn’t been time for detailed

explanations. All I know is that a colossal project of some sort is on

foot, and that The Unknown Seven is trying to put a crimp in it.”

Ballinger took his arm and led him to the smoking room. He extended

his cigar case, and Cole noticed that his fingers were long, slim,

and finely tapering, the fingers of one having a deft touch, a strong

imagination, and a lively dramatic instinct. Again Cole saw that

Ballinger’s resemblance to Doctor Latham was very slight, extending

only to outward physique. It was the disguise, and the black beard in

particular that had produced the likeness.

“Too bad about poor Reeves,” murmured Ballinger, as he held a lighted

match in his cupped hands. “His life, however, would have been only a

burden to himself and others, so in one sense it is just as well that

he was shuffled off. For professional reasons I regret his death very

keenly. I had hopes of being able to restore his brain to some degree

of normal functioning. If I had succeeded I think he would have told us

a most interesting story, and that, of course, was just what the other

side feared. However, his actions told us a great deal the other night.”

“When he seemed to recognize Doctor Latham in you?”

“Exactly. To that extent the experiment was a complete success. It was

Carlin’s idea, and the credit belongs to him. I merely carried out his

suggestions, and I didn’t particularly relish the task.” He chuckled

apologetically. “Well, the murder of Reeves is additional proof of

the fact that we are fighting a crowd of very ingenious and utterly

conscienceless scoundrels. Evidently they are directed by a master

mind, a genius of the kind we often read about, but seldom meet. You

will admit there’s a great deal of fascination about a rascal of that

type, Cole?”

Cole did not answer, but he remembered the magnetic tug he had felt in

Doctor Latham’s presence.

“I almost envy you the exciting times you will have tracking this

master mind to his lair,” Ballinger went on. “We know some of the

smaller fry in the crowd, Professor Carmody, for instance, but our

efforts won’t lead anywhere until we have found the directing genius.

And when we have found him, Cole, we will be face to face with an

interesting character. Brilliant, resourceful, unscrupulous, and full

of bewildering subtleties, the kind that kills without hesitation the

moment his plans are interfered with. I dare say you have already

suspected who he is?”

Ballinger’s eyes shone with a fine glow of enthusiasm, but it was the

unimpassioned enthusiasm of a scientist who dissects and analyzes.

“Perhaps,” said Cole guardedly. “Haven’t you?”

Ballinger smiled queerly, but the opening of the door and the

announcement that dinner was served forestalled a reply. In the

corridor they were parted by a stream of people, and Cole found an

opportunity to speak a few words in Carlin’s ear. The lawyer nodded

bewilderedly, like one receiving instructions which he does not

understand. He knew Cole had a plan of some sort, but he could not make

even a guess as to what it was.

There were some twenty-five or thirty at the table. Cole found himself

seated between Miss Brownell and Carlin. Inwardly he felt a tingling

sensation, as he contemplated the bombshell he was about to explode

among the diners, but his face showed no sign of it. Now and then he

stole a glance down the two wings of the table. He liked the faces of

the men with whom he was to work. They were an alert, keen-eyed lot,

the kind of men Cole himself would have selected.

“You are a judge of faces,” whispered Miss Brownell, leaning slightly

toward him. “Who is the traitor?”

Cole shook his head. That very question had already occurred to him.

There was not one in the gathering who by his looks could be singled

out as the traitor.

“Whom would you pick?” he whispered back.

Her glance ran quickly up and down the table. He could see that her

woman’s intuition was at work. A queer gleam came into her eyes; her

face hardened for a moment. He tried to trace her glance, but it was

too late.

“It wouldn’t be fair to tell, would it?” she said evasively. “I may be

wrong, you know.”

Cole only smiled. As nearly as he had been able to tell, her glance had

rested for an instant somewhere near the center of the left wing of the

table. He scanned the faces of the men seated there, but none of them

impressed him unfavorably, and he wondered what Miss Brownell could

have based her guess on.

The dinner progressed by easy stages, and the scene which Cole had been

rehearsing in his mind was drawing near. Carlin, seated at his right,

looked nervous, and Miss Brownell’s usually vivacious manner seemed

somewhat dampened. Finally the sauterne was opened and the waiters

filled the glasses. Carlin cleared his throat.

Noisy applause greeted the lawyer’s announcement that Cole had

accepted the management of The Unknown Seven’s activities. Then Carlin

proposed a toast, and it was drunk standing. Cole watched the faces

of the men as they quaffed their wine. In several of them he saw a

vaguely wondering look, telling him that their senses had registered

an impression so faint that as yet their minds had not grasped it. He

sipped his own wine, and he wondered whether he would have been able to

taste the foreign substance if he had not known it was there.

When Carlin finished, Cole got to his feet amid renewed handclapping.

Somewhat bluntly he thanked them for the ovation, and then he veered

sharply to the subject uppermost in his mind.

“I wonder,” he said, “how many of you can look me straight in the eye

and tell me that you are loyal to this organization.”

A breathless hush followed. His very quiet tones had created a profound

impression. In the next instant every pair of eyes in the room was

leveled at him without wavering.

“It seems to be unanimous,” he observed dryly. “One can lie, however,

with his eyes as well as with his tongue, and I know that one among you

is a liar.”

Another period of silence followed, and then came a scraping of feet

and exclamations of incredulity. Cole held up a silencing hand. His

eyes were everywhere, noting each shifting expression in the startled

faces before him.

“One of you has proven false to the organization,” he declared in

short-clipped accents. “I discovered it only a little while ago. I

found positive proof, not only of the treachery, but of the traitor’s

identity as well. He is at this table. He was one of those who only a

few moments ago looked me straight in the eyes. What shall we do with

him?”

Once more came an electric hush. Cole had spoken quietly, but with an

emphasis that carried conviction. He smiled faintly, as he met the

startled glances of the diners. A slight trace of the foreign substance

in the wine was still lingering on his tongue.

“What shall we do with him?” he asked again.

“There’s only one thing to do with a traitor,” muttered some one at

the farther end of the table, and the suggestion was followed by a

chorus of approval.

“And that thing has already been done,” declared Cole with grim

emphasis. “So that it may serve as a warning to others who may be

tempted to betray us, the traitor will die right before our eyes.

Inside one minute the poison that was put into his glass will begin to

take effect.”

Cole pretended to look at his watch, but his glance was gliding swiftly

over the two long rows of faces. He had spoken rapidly, and yet with a

quiet insistence, putting his astounding announcement into the fewest

possible words. The effect he hoped to produce depended upon a quick

assault on the guilty person’s mental faculties, shocking him off

his balance before he had time to digest the statement. In the acute

tension of the moment, the vague impression that he had received while

sipping his wine would suddenly crystallize, and then, with the fear of

death upon him, he could not help betraying himself.

At least such was the psychological effect Cole had intended, and he

had been reasonably sure that the test would succeed. Moments passed

while he stood, watch in hand, glancing out of the tail of an eye

at the faces around the table. Sixty seconds passed, and a look of

diffidence crossed his features. Here and there an impatient mutter was

heard. Carlin was looking up at him with an expression of thinly veiled

disappointment. At length Cole snapped the watch shut. He smiled rather

sheepishly.

“The trick didn’t work,” he said disgustedly. “Yes, I might as well

admit it was only a trick. The traitor was too clever to betray

himself.” With that he sat down, well aware that he had made an

unfavorable impression.

“It was too thin, Cole,” whispered Carlin in his ear. “Too bad you

didn’t consult me beforehand.”

Cole nodded dejectedly. Then he felt Miss Brownell’s gaze on his face.

He turned and saw a knowing twinkle in her eyes.

“It was very clever, Mr. Cole,” she whispered. But for all that her

face indicated she might have given him only a consoling platitude.

“You saw, of course?”

“Yes, I saw enough.” The sheepish grin still lingered on Cole’s lips.

“And you guessed right. The traitor is sitting near the center of the

left wing of the table. Doctor Ballinger is a very astute rascal. It

took him only a fraction of a second to see through my little bluff. He

is smiling behind his palm this very moment. We’ll just let him keep on

smiling for a while, eh, Miss Brownell?”
