I watched with half-suffocated respiration. Since his outline was plain it was sure mine was so likewise; but I could not distinguish that he was looking towards the place where I stood, that is, in the middle of the after bulkhead, a couple of paces from the foot of the bed, whither I had backed on his entering. He very softly closed the door, on which I drew myself up waiting for the onslaught I was certain he designed, though when I considered what thing it was I should be dealing with, the sense of my helplessness came very near to breaking me down. Having closed the door he approached the bed, and bent his head down as though listening; then, with amazing swiftness, stabbed at the bed four times, each blow, with the vehemence of it, making a distinct sound; after which he hung over the bed with his arm uplifted and his head bent as though he would make sure by listening that he had dispatched me. His figure was so plain that it was as if you should cut out the shape of a man in black paper and paste it upon a dull yellow ground. From the upraised hand I could distinguish the projection of a knife or small sword not less than a foot long. He was not apparently easily satisfied that I lay dead; for he kept his menacing, hearkening posture while I could have counted sixty; he then went lightly to the door, opened it and passed out. Whether he walked in his sleep--and certainly his motions were those of a somnambulist--or whether he was influenced by some condition of his doom, of a character as unconjecturable as the manner in which vitality was preserved among the crew, who were years and years ago dead in time, I could not conceive; but, resolved to discover him if I could, I followed on his heels, catching the door as it swung from his grasp; but there was no need to close it nor slip a foot beyond the coaming; for, the glimmer all about serving my sight, I saw him enter the cabin opposite--that in which Van Vogelaar slept, whereby I knew who it was that would have assassinated me that night had I slept when I lay down. You will easily credit that this man had murdered sleep so far as I was concerned. I would not go on deck, and I would not lie down either, for what I had beheld had so wrought in my imagination that the mere idea of resting upon the holes which the villain's blade had made in the aged mattress filled me with horror. So for the rest of the night I walked about the cabin or rested on the edge of the bed, praying for daylight, and repeatedly commending myself to God; for, this being the second time my life had been attempted by the same hand, I could not question, if it was the will of Heaven this hideous cruise should be prolonged, the third venture would be successful, and in the dreadful loneliness and luminous blackness of that cabin I viewed myself as a dead man, and could have wept with rage and grief when thinking of my helplessness and of Imogene's fate.
