The man's hot breath scorched my cheek, his hands gripped my arm with nervous force, his hysterical whisper was barely audible, although his lips were within a few inches of my ear.

"Keep quiet," he muttered, "and don't open the door!"

"Why not?" I asked.

"They will kill me," he answered simply.

I resumed my seat on the side of the bed. My sensations were a little confused. Under ordinary circumstances, I should probably have been angry. It was impossible, however, to persevere in such a sentiment towards the abject creature who cowered by my side.

Yet, after all, was he abject? I looked away from the door, and, for the second time, studied carefully the features of the man who had sought my protection in so extraordinary a manner. He was clean shaven, his features were good; his face, under ordinary circumstances, might have been described as almost prepossessing. Just now it was whitened and distorted by fear to such an extent that it gave to his expression a perfectly repulsive cast. It was as though he looked beyond death and saw things, however dimly, more terrible than human understanding can fitly grapple with. There were subtleties of horror in his glassy eyes, in his drawn and haggard features.

Nothing, perhaps, could more completely illustrate the effect his words and appearance had upon me than the fact that I accepted his extraordinary statement without any instinct of disbelief! Here was I, an Englishman of sound nerves, of average courage, and certainly untroubled with any superabundance of imagination, domiciled in a perfectly well-known, if somewhat cosmopolitan, London hotel, and yet willing to believe, on the statement of a person whom I had never seen before in my life, that, within a few yards of me, were unseen men bent upon murder.

From outside I heard a warning chink of metal, and, acting upon impulse, I stepped forward and slipped the bolt of my door. Immediately afterwards a key was softly inserted in the lock and turned. The door strained against the bolt from some invisible pressure. Then there came the sound of retreating footsteps. We heard the door of the next room opened and closed. A moment later the handle of the communicating door was tried. I had, however, bolted it before I commenced to undress.

"What the mischief are you about?" I cried angrily. "Can't you leave my room alone?"

No answer; but the panels of the communicating door were bent inwards until it seemed as though they must burst. I crossed the room to where my portmanteau stood upon a luggage-rack, and took from it a small revolver. When I stood up with it in my hand, the effect upon my visitor was almost magical. He caught at my wrist and wrested it from my fingers. He grasped it almost lovingly.
