The next look in that direction was enough. The dull, black, frowsy outline of the valance above me was within an inch of being parallel with his waist. I still looked breathlessly. And steadily and slowly—very slowly—I saw the figure, and the line of frame below the figure, vanish, as the valance moved down before it.

I am, constitutionally, anything but timid. I have been on more than one occasion in peril of my life, and have not lost my self-possession for an instant; but when the conviction first settled on my mind that the bed-top was really moving, was steadily and continuously sinking down upon me, I looked up shuddering, helpless, panic-stricken, beneath the hideous machinery for murder, which was advancing closer and closer to suffocate me where I lay.

I looked up, motionless, speechless, breathless. The candle, fully spent, went out; but the moonlight still brightened the room. Down and down, without pausing and without sounding, came the bed-top, and still my panic terror seemed to bind me faster and faster to the mattress on which I lay—down and down it sank, till the dusty odor from the lining of the canopy came stealing into my nostrils.

At that final moment the instinct of self-preservation startled me out of my trance, and I moved at last. There was just room for me to roll myself sidewise off the bed. As I dropped noiselessly to the floor, the edge of the murderous canopy touched me on the shoulder.

Without stopping to draw my breath, without wiping the cold sweat from my face, I rose instantly on my knees to watch the bed-top. I was literally spellbound by it. If I had heard footsteps behind me, I could not have turned round; if a means of escape had been miraculously provided for me, I could not have moved to take advantage of it. The whole life in me was, at that moment, concentrated in my eyes.

It descended—the whole canopy, with the fringe round it, came down—down—close down; so close that there was not room now to squeeze my finger between the bed-top and the bed. I felt at the sides, and discovered that what had appeared to me from beneath to be the ordinary light canopy of a four-post bed was in reality a thick, broad mattress, the substance of which was concealed by the valance and its fringe. I looked up and saw the four posts rising hideously bare. In the middle of the bed-top was a huge wooden screw that had evidently worked it down through a hole in the ceiling, just as ordinary presses are worked down on the substance selected for compression. The frightful apparatus moved without making the faintest noise. There had been no creaking as it came down; there was now not the faintest sound from the room above. Amidst a dead and awful silence I beheld before me—in the Nineteenth Century, and in the civilized capital of France—such a machine for secret murder by suffocation as might have existed in the worst days of the Inquisition, in the lonely inns among the Hartz Mountains, in the mysterious tribunals of Westphalia! Still, as I looked on it, I could not move, I could hardly breathe, but I began to recover the power of thinking, and in a moment I discovered the murderous conspiracy framed against me in all its horror.

My cup of coffee had been drugged, and drugged too strongly. I had been saved from being smothered by having taken an overdose of some narcotic. How I had chafed and fretted at the fever fit which had preserved my life by keeping me awake! How recklessly I had confided myself to the two wretches who had led me into this room, determined, for the sake of my winnings, to kill me in my sleep by the surest and most horrible contrivance for secretly accomplishing my destruction! How many men, winners like me, had slept, as I had proposed to sleep, in that bed, and had never been seen or heard of more! I shuddered at the bare idea of it.

But ere long all thought was again suspended by the sight of the murderous canopy moving once more. After it had remained on the bed— as nearly as I could guess—about ten minutes, it began to move up again. The villains who worked it from above evidently believed that their purpose was now accomplished. Slowly and silently, as it had descended, that horrible bed-top rose toward it former place. When it reached the upper extremities of the four posts, it reached the ceiling too. Neither hole nor screw could be seen; the
