More moving floor. Another door. The door receded and showed a black hole. Again the deep voice--

"Good place--safe--just quill-pusher--dump."

A headlong flight through darkness, falling, falling, into the bottomless pit. A crash. And Martin's mind and Martin's body became one again as he struck the floor.

He was lying face downward upon a bare floor. He sat up. His head was ringing, and he could feel that his cheek was swelling. His addled wits slowly settled themselves. He moved his head about and took stock, as well as he could, of his new surroundings.

He retained a vague memory of his pa.s.sage through the big room, and of the two doors. So, he knew the place he had been so unceremoniously dumped into was one of the rooms that opened upon Carew's headquarters.

The only light that entered the place crept under the door from the room without. He knew, without experiment, the door was locked upon him.

The room felt bare. He struck one of his few remaining matches. The room was bare, not a stick of furniture in it. The single window was closed, and he supposed it was shuttered as well, for he could not see through it. But he would make sure. He clambered to his feet, a bit dizzy yet but well able to control his movements. He moved softly toward the window, feeling his way.

In a second his hand touched the window-ledge. He felt along the sash and shoved upward. To his surprise, the window lifted easily. But the hand he shoved without met, as he expected it would, a heavy wooden shutter; and his investigating fingers disclosed, moreover, a padlock, that, by means of a staple sunk in the sill, locked the shutter fast.

No hope of getting away through the window.

The certainty that he was imprisoned in this sealed box of a room was not soothing to Martin's temper. He was not frightened--he was angry.

The haughty Carew had aroused in him resentment; now, he had been slugged semi-conscious and locked in this room. His anger reached the proportions of a rage, a hot, furious rage.

He left the window and crossed to the door. He did not try this time to soften his footfalls--he did not care who heard him.

He tried the door. Locked. He shook it, and rattled it. No response, but his straining ears caught the sound of light footfalls without.

He pounded upon the door, shouted threats, demands, challenges. He was in the mood to flog the whole vile brood of this Pension Spulvedo.

He resorted to the method that had brought him freedom once before that night--he lifted his foot and drove his boot against the door. And, as before, the response was immediate.

A peremptory voice was raised in the other room.

"Be quiet, you, een there! Eef you be not quiet, I feex you!"

A well-remembered voice! That greasy villain of a saloonkeeper was out there! It was Spulvedo who had smote him on the jaw. Martin redoubled his blows on the door.

"Stop! _Santa Maria_, eef you not stop, I shoot!"

Martin kicked away. The door, of flimsy enough construction, seemed on point of giving way. Then, there happened in such rapid sequence as to seem simultaneous, several things.

There was an ear-splitting crash, a splintering of wood, a hot streak pa.s.sing so close to Martin's head it scorched, a tinkle of broken gla.s.s from the window behind him, a smell of burnt gunpowder.

Martin stood on one leg, like a stork, his free foot suspended for the kick he did not deliver. There was a queer sinking feeling in that inward organ that received his food. He stared at a little hole in the door panel, just above his head--a little bullet-hole that glowed yellow with the light from the other room. The man had shot through the door at him!

"Eef you not stop the keek, I shoot lower!" came the voice.

Martin sat down quickly upon the floor. Then, on second thought, he crawled into the nearest corner and crouched against the wall.

To be shot at, to have Death's hot breath scorch one's very hair, might very well daunt a person of more tumultuous antecedents than Martin Blake. To a young man whose chief occupation in life has been the warming of an office chair, such an experience is apt to prove unnerving. It spoke well of the stuff Martin was made of that he was not overly frightened. But Martin was certainly a bit shaken.

He suddenly discovered there was a vast difference between braving death in spirit in the pages of a book, and braving death in person in a locked upstairs room of a dubious and isolated boozing den. It was all very well for, say, Roger De Puyster, hero of that sw.a.n.king tale "Death before Dishonor" to disregard such trifles as revolver shots and threats of death. But as for Martin Blake, law clerk, well, he squatted low and hugged close in his corner. No panic gripped him, but the instinct of self-preservation is a primal instinct. Martin's condition of mind, for the moment, was that bromidic state, "better imagined than described."

Chiefly, he was astonished. He, Martin Blake, had at last encountered a real adventure! He, the obscure law clerk and messenger, whose existence was a drab routine, whose every act must favor dull convention, had suddenly tumbled into the meshes of a dark intrigue, undoubtedly unlawful, where men's violent pa.s.sions were given free rein.

In the short s.p.a.ce of a half-hour, he had witnessed an abduction, been a.s.saulted, imprisoned, murderously shot at! These things had happened to him, to Mrs. Meagher's star boarder, to Martin Blake, the despised quill-pusher! There was in Martin's mood, as he crouched there in the corner, that transcended his anger, his wonder, his fear, something that was close akin to exhilaration.

It was very still. His thumping heart seemed to him to be the only sound that reached his straining ears.

What was going on out there in the big room? He had not heard Carew's voice. Was the captain still there? Was Spulvedo crouching without the door, pistol raised, waiting for him to "keek"? Where were the mysterious j.a.panese? What were they--Carew's men or Dr. Ichi's?

Strange thing about that envelope. Martin had been as much surprised as Carew at the contents. What kind of a game were Smatt and Ichi playing, sending him with injunctions of secrecy to deliver sheets of blank paper? Carew declared the envelope had been tampered with, but Martin knew better. It had not left his possession. Had Smatt foreseen the reception that would be accorded his messenger? He did not doubt it. Smatt was a cold-blooded fish; he would not hesitate to risk his clerk's skin if a dollar profit were in sight. Did Smatt and Ichi know about the abduction--the imprisonment of that girl who masqueraded in the gray overcoat?

Aye, the girl--that was the important thing! Who was she? Where had she been taken? If he could only get word to the police! He had no fears for himself, at least, not many. When Carew had adjusted the matter of the envelope with Smatt and Ichi, why, of course, he would be turned loose. But the woman--those yellow men....

Martin's ears became suddenly aware of a faint, strange sound. It was a sound he had been endeavoring subconsciously to place during the period of his musing; he had almost identified it as his heart-beats.

Now, alert and listening, he placed it. It was a tapping on the other side of the wall he leaned against, a light tap-tap-tap. It started, stopped, started.

Somebody was tapping on the wall in the next room. Another prisoner!

It was the girl--of course, it was the girl.

Martin was instantly sure of the tapper's ident.i.ty, with a sureness born of intuition and memory. He remembered the two doors opening from the big room, the gray overcoat lying in the corner, Carew's words when the semi-conscious Martin Blake was held poised before the other door.

"Not there--next room." Those were Carew's words. Why, of course, the j.a.ps had brought the girl to Carew, and he had shut her in the next room.

_Tap-tap-tap, tap-tap_. There it came again. Martin rapped against the wall with his own knuckles, paused, rapped again. Instantly came the response from the other side, the same number of raps. A plain answer.

But Martin's elation was short lived. The unseen tapper immediately commenced again, _tap-tap, tap-tap-tap-tap, tap_.

Surely there was method in that irregular tapping. A signal, a talk in code! But he could not read it. Nor dare he lift his voice in shouted communication through the wall--Spulvedo, and bullets, hung over him.

One experience of being shot at while unarmed and helpless was sufficient. It would not help the girl for him to get himself shot.

The unevenly tapped message came again. The best he could do was repeat the taps. But this, evidently, did not satisfy the sender. The tapping on the other side ceased. Though he rapped till his knuckles were sore, he could not induce the other to recommence.

The gloom of the room was less dense, Martin's accustomed eyes being now able to discern all four walls and the outline of the window.

A-fever with excitement as he was, the inactivity palled upon him, became unbearable. He must do something. Well, he would try the window again.

But first he crept to the door and endeavored to peer through the key-hole into the big room. He hoped to get a view of what was happening without, of Carew, of Spulvedo. But he was disappointed.

The key, thrust in the lock on the outer side, completely barred any outlook. He pressed his ear against the door, but heard nothing.

A second later he was at the window, feeling of the padlocked shutter.

He drew his penknife from his pocket. It was a tiny, ridiculous blade, and it seemed futile to hope it would dig that stout staple out of the sill; still, thought Martin, any sort of attempt was better than no attempt.

He leaned over the sill and pecked away with his office tool. Of a sudden, a draft of cold, fresh air rushed up into his face. At the same instant, his other hand, which was leaning against the shutter, felt the shutter bulge slightly outward, and his ears caught a distinct, but not loud, sc.r.a.ping sound.

The sound increased, the bulge increased, the draft increased. Martin felt the staple that held the padlock bending, felt, also, the prying edge of a small steel bar between the sill edge and the shutter. Some one was outside, breaking entrance.

He drew to one side, shrinking against the wall, instinctively holding his breath. The prying of the shutter from without steadily continued.

Conjectures and hopes surged through his mind--it was a burglar, it was the police, it was some unknown, unguessed friend. He didn't care who it was so long as the shutter was opened.

His heart beat a ba.s.s-drum solo against his ribs. There were distinct, rasping creaks from the window-sill--the staple was groaning at being hauled from its wooden bed. There was a sharp crack, and the shutter swung open. Martin heard a relieved grunt, felt the cool, fresh air enveloping him, and saw a square of black sky, lighted with a few stars.

A hand grasped the window-sill and slid along it. Martin stared at the hand, fascinated. It seemed no more than a writhing shadow.
