II.

For two hours Nadine Nelson had sat, white-faced but steady-voiced, as

the three men questioned, cajoled, badgered, and threatened. At her

right, his chair within a foot of that in which she sat, was the man who

had posed as a servant. At her left was another, just as keen-eyed and

alert. Before her sat a heavy-chinned, broad-shouldered man whose

fingers crackled the typewritten sheets as he jerked out his questions.

The girl’s eyes met his fairly, unwaveringly. Yet she knew he was Chief

Whittson, of the United States secret service.

“You know that, for months, hundreds of thousands of dollars have been

passed through the agency of your father’s bank?” he snapped.

“I know nothing,” she said unemotionally.

“Then why did you say----” He referred to the typewritten sheets: “‘It

will all come out right?’”

“Because it will,” she replied steadily.

The men at her sides snorted impatiently.

“Did you know that your father was the head of the best-organised

counterfeiting gang in the country?” jerked out the secret-service

chief.

Her eyes did not flinch for an instant. “I knew nothing.”

“Where is your father, Miss Nelson?”

“I do not know.”

“Then why did you say”--his forefinger punched the typewritten page

viciously, and in his voice was snarled impatience--“‘he has gone to

them at last.’ Who did you mean?”

“I know nothing,” came the unvarying answer she had given a hundred

times before.

“Why didn’t you call in the police when you knew that your father had

disappeared?”

For the first time a shade of expression came to the girl’s face; her

lips curved in contempt. “Because I knew that the police could do no

more than the secret-service men of the United States.” There was more

than a tinge of contempt in her voice.

Chief Whittson straightened back in his chair. “Did you know that your

servant was not what he pretended to be?” he demanded.

“Yes,” she said defiantly. “We knew from the first that he was a spy.”

The former servant leaped to his feet, face red with rage. “So that’s

why you took it so cool, eh? That’s why you didn’t raise the fuss I

expected?” he flared. “And you went to your own room and locked the

door to cry. And I was _sorry_ for you. Me! A wise guy!

Some--clever--actress!”

She shrank back before the lashing sneer in the words.

“Then you knew of the dictograph?” demanded the chief, instantly alert

to take advantage of the first signs of break-down.

“Yes,” she whispered tremulously. “We knew, and we----” she stopped, her

breath catching suddenly.

“‘We,’” repeated the chief sharply. “What? What?”

Her lips quivered piteously. The nerve that had forced her frail woman’s

body to bear the rack for hours was breaking.

“What did you do? Tell me!” he commanded viciously.

“Don’t you think you’ve gone quite far enough on that line?” The quiet,

even voice of the man in the door-way caused the two men at the girl’s

side to leap to their feet, and the chief to jerk his body erect. “If I

were you, Miss Nelson,” the man in the door-way spoke to the girl, and

his voice was gentle, “I would answer only courteous questions.”

His white face, with its lean, cleft chin, and thin, firm lips, lighted

in a wonderful smile of encouragement; the hand that was not holding the

slim stick brushed back from his high forehead the hair whose whiteness

was accentuated by the great blue circles of the tortoise-rimmed library

glasses.

“Who are you?” demanded the chief, but there was no bluster in his tone.

The manner he had assumed for the girl had dropped like a mask. He was

the calm, alert detective once more, and his keen judgment told him

instantly that the new comer was not the type to bluff.

Before the man at the door-way could answer, a youth rushed past him to

the girl’s side.

“I found him, Nadine,” he cried joyously. “Here’s Mr. Colton. He’ll find

uncle.”

“Thank God!” breathed the girl, and her body relaxed.

Thornley Colton turned his head to speak over his shoulder. “A glass of

water, Sydney. Quickly!”

“So you’re Thornley Colton, eh?” The secret-service chief eyed him

sharply. “I understand you’ve done some rather remarkable work--for a

blind man.”

Colton smiled, then stepped aside as his black-haired, apple-cheeked

secretary came in with a glass of water. The girl’s eyes fluttered open,

and the blind man realised that she needed time to regain her scattered

senses.

“You have the average person’s idea of the blind, chief,” he said. “And

the average person gets _his_ notion from the blind beggar on the

street-corners who hobbles along led by a small boy and a dog, and taps

every inch of the side-walk with a heavy cane. Very few realise that is

mostly for effect. Fewer still know that in New York there are nearly

two hundred sightless men and women who go to business every day without

help or guidance. Some of the highest-paid private secretaries and

stenographers in the country are blind. Several of the blind

proof-readers are famous. And for many years the court of last resort in

the dead-letter office at Washington was a blind man. He was the most

expert ever employed by the government, and could read with his

supersensitive finger-tips addresses that had passed through the hands

of the keenest-eyed readers of illegible writing in the world. So you

see, the blind are not so helpless as one might imagine. Ah, Miss

Nelson, do you feel better?”

“Yes.” She looked up at him with a curious expression in her eyes. It

was the look of a child who has sought a protector only to be a little

frightened at the result. But she smiled bravely. “You did such a

wonderful thing for Ned”--she rested her hand fondly on her cousin’s

arm--“when he was arrested for the murder of the girl in the theatre,

and I thought----” Again came the look that was almost fear.

“I will do my best,” promised the blind man. “Do you mind my hearing the

story from Chief Whittson--his side of it?”

“No,” she said, with only a bit of nervousness in her voice.

Whittson smiled quizzically. This blind man might be interesting. On his

face and the faces of his men there was no doubt of the outcome. They

were government men, trained, efficient; the interloper was an

amateur--and blind.

“We know that Dryden F. Nelson was the biggest passer of counterfeit

money in the country!” began the chief. “He is the cleverest of them

all. Who would suspect the bank of a man like Nelson as a clearing house

for the cleverest counterfeits ever made? The scheme was wonderful, the

only organised gang in the country who could pass ‘queer’ at its face

value was that of this girl’s father. How long it’s been going on we

don’t know. The bills have the ‘feel,’ something no other counterfeiter

has ever been able to get. It was only within the past six months we

traced the bills to their source. And that was Nelson’s bank! For six

months we have tried to locate the plant, and failed. For the past three

weeks my man here has been in the house, and there has been a dictograph

in the library.”

“And you discovered nothing?”

“Nothing except to make morally certain his guilt. And he knew we were

closing in. He was frightened stiff! Now we find out that the girl,

here, was wise. She’s fooled us right along. We never suspected that she

was one of the gang.”

The girl cowered in her chair. “I’m not,” she faltered. “It isn’t true.”

“Now Nelson’s slipped through our fingers,” went on the chief

relentlessly. “Just when we had him worked up to a confession. He got

out of that room in some devilish way.”

“I’ve got the facts of his disappearance,” put in Colton.

“So have we!” snapped the chief. “Within ten minutes of the time he

went, every inch of this block was covered, and to-day ten thousand

police and two hundred secret-service men are scouring the city for him.

He can’t get out of it, and he can’t stay in it--long.”

“Why didn’t you arrest him before if you were so certain of his guilt?”

“Because we wanted his pals! We wanted to locate the plant! And he went

while Jim was watching the door every minute! While my ears were glued

to the dictograph-receivers and my pencil taking every word down in

shorthand.”

“You heard nothing?”

“After Jim brought the wine there wasn’t a sound but the infernal

ringing of the two glass rims on the teetery tabouret he insisted on

having beside his chair.”

Colton looked up with sudden interest. “Did you ever hear those glasses

ring before?”

“Every night at eight, when Jim here served his wine.”

“What other time did he have wine served?”

The former servant answered: “He only had it at eight in the library,

and he wanted it on the minute.”

“Significance--somewhere,” mused the problemist. For several seconds

there was silence as his slim cane idly tapped his shoe-sole.

Suddenly the girl sat rigid in her chair. “I can’t!” she cried. “Oh,

please! Please! I can’t!”

The expression on the blind man’s face was the only one that did not

change. The three secret-service men looked the amazement the sudden

irrelevant words had caused. The youth who was kneeling at the girl’s

side gazed at her in wonder.

“The truth will help us all, Miss Nelson,” said Colton gently.

But she paid no attention to the words. Her eyes, widened in fear, were

fixed on the shoe of the problemist.

“Yes,” she said, and her voice was barely a whisper. “Every night!”

The chief jumped to his feet. “What’s that?” he demanded. “What’s that?”

“The one thing you overlooked; the significance of two plus two,”

declared Thornley Colton. “If you will show me the library perhaps I can

point out some other things that your eyes have missed.”

The girl lifted her bowed head. “Oh, Mr. Colton,” she pleaded, “do not

show them--you don’t know what it means!”

The blind man went to her side, and put his hand gently on her shoulder.

“It is necessary,” he said, and his voice was tender. Then, to the

chief: “If you will lead the way.”

Chief Whittson rose, and jerked his thumb toward the girl as she buried

her head in her arms. One of the men nodded. She was to be guarded every

minute.

“I’ll stay here,” whispered Sydney Thames, as Colton passed him. The

black-haired secretary, tender-hearted, deifier of all women, was going

to guard the girl against further badgering.

The government man who had posed as the servant opened the door of the

library. “This is the room,” he growled. “There isn’t a break in the

walls. We’ve gone over every inch.”

Colton’s thin cane located the big chair near the door. He walked around

it, touched its back, the walls behind it, and measured the distance to

the room entrance. On his white cheeks was a hectic flush of excitement;

his nostrils quivered like those of a hound on the scent.

“You were watching the door every minute?” His voice was unconsciously

sharp.

“Yes.”

The blind man turned to the chief, a curious smile on his face. “This is

an instance of the blind’s superiority. You and your man know that there

is but one possible way for a man to get out of this room. You’re as

sure of that as you are of death. Yet you can’t realise that that is the

way Nelson got out because your eyes deceive your brain into thinking it

impossible. Sight is the greatest handicap pure reasoning has. Even a

man with eyes instinctively closes them when he is trying to figure out

some particularly intricate problem. The trouble is that you haven’t

closed your eyes. Nelson went out through that door!”

“What?” The chief and his man chorused it blankly.

The blind problemist did not answer at once. He darted across the room.

His stick found the chair at the fire-place.

“Nelson wanted you to turn this chair away from the fire?” he said

suddenly.

“How did you know that?” asked the chief, and in his tone was wonder.

“Because it was necessary for his escape.” The words came like staccato

notes on a taut wire. “He knew that a man was watching that door. He

didn’t know what instant it might open an inch. But he knew that with

the high sides of the chair toward the fire he would be invisible in the

depths. He pulled his slippers off, and left one so that it could be

seen--young Nelson, who came to see his cousin last night, gave me most

of the facts. Then he slid from the chair, and crawled across the floor

to crouch down behind that other big chair near the door. From past

tests he knew just how the servant would enter the room and just what he

would do. It was the work of an instant to slip through the open door as

the servant was crossing the room toward the fire-place. His stockinged

feet made his exit absolutely noiseless. The very simplicity of the

thing would deceive any man in the world who could _see_. Yet you knew

it was the only way he _could_ have gone!”

“I saw the door open!” gasped the secret-service man. “I thought it was

a draught.”

“Yes,” nodded the blind man, “because your eyes saw the cigar-smoke and

the slipper. They wouldn’t let your brain get any idea but that he was

in the chair.”

“But the very simplicity of that would make elaborate preparations

necessary,” objected the chief. “The thing would have to be timed to the

instant. Nelson hadn’t a chance to communicate with any one without our

knowledge. Jim, here, and the dictograph took care of that.”

Colton’s lips curved in a mirthless smile. “They made it possible! Their

very actions prove that both Nelson and his daughter knew of the

dictograph. They understood that, so long as you didn’t suspect they

knew, you would take no other precautions. They knew that you would

depend on the instrument to hear every word, and on this man to see that

there wasn’t a written word of instruction put into their hands. And

they fooled you! Tricked you every day!”

At the last word he dropped to his knees beside the big chair by the

fire-place. His supersensitive finger-tips brushed the carpet. Back and

forth they went a dozen times, then stopped. “See that!” he cried. “See

that!”

The two men leaned forward. For a minute they stared.

“Only a nail-hole through the rug,” declared the chief.

“Yes, only a nail-hole,” Colton repeated quietly. “That’s the only thing

your eyes can see. But my finger-tip felt the point of a nail under the

carpet and on a level with the floor.”

“Nail?” repeated the chief dumbly. He had forgotten his superior

attitude of a short time before. The dominant personality of the blind

man; his absolute sureness of himself compelled respect, and brought a

realisation that Thornley Colton was the master, he the pupil.

The blind man walked from the chair. His stick, poking in the corner

beside the fire-place, found the tabouret. With an exclamation of

satisfaction he pulled it out and touched its edge with his finger-tips.

“You spoke of it as being ‘teetery.’ See how finely it is balanced on

the two legs that are a fraction of an inch longer than the others. And

see here!” His stick fell to the floor as he used both hands to turn it

upside-down. The two secret-service men saw that all four legs were

tipped with metal balls. “See the scars of the nail-point on the balls

of the short legs?” cried Colton. He took his knife from his pocket, and

tapped with the blade. A low, musical click-click-click that could be

heard distinctly by the men resulted. “Hear that?” he demanded.

“What does it mean?” The chief made no effort to keep the bewilderment

from his voice.

“It means that under the floor, and under that nail-hole in the rug, is

a finely-adjusted magnet with a nail-pointed plunger in the centre of

the coil. That’s how Nelson beat your dictograph! That’s how he beat

your spy. Just as the girl inside understood the Morse messages I tapped

with my cane.”

“Telegraphy!” gasped the chief. “Nelson was chief staff-telegrapher in

the army for years.”

The blind man nodded. “The table was set here at eight because that is

the time the person at the other end would be ready to send the

messages. Nelson adjusted the tabouret so that one of the short legs

would be directly above the magnet-plunger, which was as sensitive to

the touch of the telegraph-key sending the current through the

magnet-coils as the most delicate instrument in the world. To the

trained operator who has learned to take a message from any single

instrument in a room where a thousand others are clattering away, the

click of the plunger against that hollow metal ball would be as easy to

read as print to the average man. But ordinarily the dictograph would

also hear. That’s why the goblets were placed rim to rim--so that the

ringing would drown the other sound over the wires of the dictograph, or

to a man listening at the door. Acoustics would take care of that. The

dot-dash of the magnet-plunger could not be heard five feet away, though

the man in the chair could get every word.”

“By God, that’s clever!” There was admiration in Chief Whittson’s tone.

“Pull back that chair, Jim! We’ll get the rug up and see the thing!

We’ll follow those wires and land the whole gang.”

He stopped as Nadine Nelson entered the room. She wasn’t the sobbing

girl they had left who now entered; but a white-cheeked, white-lipped

woman who did not speak until she had crossed the room and stood before

the chief.

“I am the ‘gang’ you speak of,” she said quietly. “The wires go to my

room!”
