"You know quite well of what I am speaking! You know that you can tell me if any one can! The fact that you go disguised alone condemns you! Why should I remind you of our previous meetings--of the links which bind you to the history of the Prophet's slipper?"

She shuddered and closed her eyes. "Your present att.i.tude is a sufficient admission!"

She stood silent before me, with something pitiful in her pose--a wonderfully pretty woman, whose disarranged hair and dilapidated hat could not mar her beauty; whose clumsy, ill-fitting garments could not conceal her lithe grace.

Our altercation had not thus far served to arouse any of the inhabitants and on that stuffy landing, beneath the flickering gaslight, we stood alone, a group of two which epitomized strange things.

Then, with that quietly dramatic note which marks real life entrances and differentiates them from the loudly acclaimed episodes of the stage, a third actor took up his cue.

"Both hands, Mr. Cavanagh!" directed an American voice.

Nerves atwitch, I started around in its direction.

From behind the slightly opened door of No. 48 protruded a steel barrel, pointed accurately at my head!

I hesitated, glancing from the woman toward the open door.

"Do it quick!" continued the voice incisively. "You are up against a desperate man, Mr. Cavanagh. Raise your hands. Carneta, relieve Mr. Cavanagh of his gun!"

Instantly the girl, with deft fingers, had obtained possession of my revolver.

"Step inside," said the crisp, strident voice. Knowing myself helpless and quite convinced that I was indeed in the clutches of desperate people, I entered the doorway, the door being held open from within. She whom I had heard called Carneta followed. The door was reclosed; and I found myself in a perfectly bare and dim pa.s.sageway. From behind me came the order--

"Go right ahead!"

Into a practically unfurnished room, lighted by one gas jet, I walked. Some coa.r.s.e matting hung before the two windows and a fairly large grip stood on the floor against one wall. A gas-ring was in the hearth, together with a few cheap cooking utensils.

I turned and faced the door. First entered Carneta, carrying the basket; then came a man with a revolver in his left hand and his right arm strapped across his chest and swathed in bandages. One glance revealed the fact that his right hand had been severed--revealed the fact, though I knew it already, that my captor was Earl Dexter.

He looked even leaner than when I had last seen him. I had no doubt that his ghastly wound had occasioned a tremendous loss of blood.

His gaunt face was positively emaciated, but the steely gray eyes had lost nothing of their brightness. There was a good deal about Mr. Earl Dexter, the cracksman, that any man must have admired.

"Shut the door, Carneta," he said quietly. His companion closed the door and Dexter sat down on the grip, regarding me with his oddly humorous smile.

"You're a visitor I did not expect, Mr. Cavanagh," he said. "I expected someone worse. You've interfered a bit with my plans but I don't know that I can't rearrange things satisfactorily. I don't think I'll stop for supper, though--" He glanced at the girl, who stood silent by the door.

"Just pack up the provisions," he directed, nodding toward the basket--"in the next room."

She departed without a word.

"That's a noticeable dust coat you're wearing, Mr. Cavanagh," said the American; "it gives me a great notion. I'm afraid I'll have to borrow it."

He glanced, smiling, at the revolver in his left hand and back again to me. There was nothing of the bully about him, nothing melodramatic; but I took off the coat without demur and threw it across to him.

"It will hide this stump," he said grimly; "and any of the Hashishin gentlemen who may be on the look-out--though I rather fancy the road is clear at the moment--will mistake me for you. See the idea?

Carneta will be in a cab and I'll be in after her and away before they've got time to so much as whistle."

Very awkwardly he got into the coat.

"She's a clever girl, Carneta," he said. "She's doctored me all along since those devils cut my hand off."

As he finished speaking Carneta returned.

She had discarded her rags and wore a large travelling coat and a fashionable hat.

"Ready?" asked Dexter. "We'll make a rush for it. We meant to go to-night anyway. It's getting too hot here!" He turned to me.

"Sorry to say," he drawled, "I'll have to tie you up and gag you.

Apologize; but it can't be helped."

Carneta nodded and went out of the room again, to return almost immediately with a line that looked as though it might have been employed for drying washing.

"Hands behind you," rapped Dexter, toying with the revolver--"and think yourself lucky you've got two!"

There was no mistaking the manner of man with whom I had to deal, and I obeyed; but my mind was busy with a hundred projects. Very neatly the girl bound my wrists, and in response to a slight nod from Dexter threw the end of the line up over a beam in the sloping ceiling, for the room was right under the roof, and drew it up in such a way that, my wrists being raised behind me, I became utterly helpless. It was an ingenious device indicating considerable experience.

"Just tie his handkerchief around his mouth," directed Dexter: "that will keep him quiet long enough for our purpose. I hope you will be released soon, Mr. Cavanagh," he added. "Greatly regret the necessity."

Carneta bound the handkerchief over my mouth.

Dexter extinguished the gas.

"Mr. Cavanagh," he said, "I've gone through h.e.l.l and I've lost the most useful four fingers and a thumb in the United States to get hold of the Prophet's slipper. Any one can have it that's open to pay for it--but I've got to retire on the deal, so I'll drive a hard bargain! Good-night!"

There was a sound of retreating footsteps, and I heard the entrance door close quietly.

CHAPTER XVIII

WHAT CAME THROUGH THE WINDOW

I had not been in my unnatural position for many minutes before I began to suffer agonies, agonies not only physical but mental; for standing there like some prisoner of the Inquisition, it came to me how this dismantled apartment must be the focus of the dreadful forces of Ha.s.san of Aleppo!

That Earl Dexter had the slipper of the Prophet I no longer doubted, and that he had sustained, in this dwelling beneath the roof, an uncanny siege during the days which had pa.s.sed since the theft from the Antiquarian Museum, was equally certain. Helpless, gagged, I pictured those hideous creatures, evil products of the secret East, who might, nay, who must surround that place! I thought of the horrible little yellow man who lay dead in Wyatt's Buildings; and it became evident to me that the house in which I was now imprisoned must overlook the back of those unsavoury tenements. The windows, sack-covered now, no doubt commanded a view of the roofs of the buildings. One of the mysteries that had puzzled us was solved. It was Earl Dexter who had shot the yellow dwarf as he was bound for this very room! But how humanly the Hashishin had proposed to gain his goal, how he had travelled through empty s.p.a.ce--for from empty s.p.a.ce the shot had brought him down--I could not imagine.

I knew something of the almost supernatural attributes of these people. From Professor Deeping's book I knew of the incredible feats which they could perform when under the influence of the drug hashish. From personal experience also I knew that they had powers wholly abnormal.

The pain in my arms and back momentarily increased. An awesome silence ruled. I tortured myself with pictures of murderous yellow men possessed of the power claimed by the Mahatmas, of levitation. Mentally I could see a distorted half-animal creature carrying a great gleaming knife and floating supernaturally toward me through the night!

A soft pattering sound became perceptible on the sloping roof above!

I think I have never known such intense and numbing fear as that which now descended upon me. Perhaps I may be forgiven it. A more dreadful situation it would be hard to devise. Knowing that I was on the fifth story of a house, bound, helpless, I knew, too, that a second mystic guardian of the slipper was come to accomplish the task in which the first had failed!

I began to pray fervently.
