He was sitting in his old position when I entered, and there were no signs of the mysterious movements which I had overheard, though his chubby face was flushed as with recent exertion.
"Are you succeeding all right?" I asked as I came in, putting on as careless an air as possible, but glancing involuntarily round the room to see if we were alone.
"Only your help is needed to complete the matter," said Mr. Abrahams, in a solemn voice. "You shall sit by me and partake of the essence of Lucoptolycus, which removes the scales from our earthly eyes. Whatever you may chance to see, speak not and make no movement, lest you break the spell." His manner was subdued, and his usual cockney vulgarity had entirely disappeared. I took the chair which he indicated, and awaited the result.
My companion cleared the rushes from the floor in our neighbourhood, and going down upon his hands and knees, described a half circle with chalk, which enclosed the fireplace and ourselves. Round the edge of this half circle he drew several hieroglyphics, not unlike the signs of the zodiac. He then stood up and uttered a long invocation, delivered so rapidly that it sounded like a single gigantic word in some uncouth guttural language. Having finished this prayer, if prayer it was, he pulled out the small bottle which he had produced before, and poured a couple of teaspoonfuls of clear transparent fluid into a phial, which he handed to me with an intimation that I should drink it.
The liquid had a faintly sweet odour, not unlike the aroma of certain sorts of apples. I hesitated a moment before applying it to my lips, but an impatient gesture from my companion overcame my scruples, and I tossed it off. The taste was not unpleasant; and, as it gave rise to no immediate effects, I leaned back in my chair and composed myself for what was to come. Mr. Abrahams seated himself beside me, and I felt that he was watching my face from time to time while repeating some more of the invocations in which he had indulged before.
A sense of delicious warmth and languor began gradually to steal over me, partly, perhaps, from the heat of the fire, and partly from some unexplained cause. An uncontrollable impulse to sleep weighed down my eyelids, while, at the same time, my brain worked actively, and a hundred beautiful and pleasing ideas flitted through it. So utterly lethargic did I feel that, though I was aware that my companion put his hand over the region of my heart, as if to feel how it were beating, I did not attempt to prevent him, nor did I even ask him for the reason of his action. Everything in the room appeared to be reeling slowly round in a drowsy dance, of which I was the centre. The great elk's head at the far end wagged solemnly backward and forward, while the massive salvers on the tables performed cotillons with the claret cooler and the epergne. My head fell upon my breast from sheer heaviness, and I should have become unconscious had I not been recalled to myself by the opening of the door at the other end of the hall.
This door led on to the raised dais, which, as I have mentioned, the heads of the house used to reserve for their own use. As it swung slowly back upon its hinges, I sat up in my chair, clutching at the arms, and staring with a horrified glare at the dark passage outside. Something was coming down it—something unformed and intangible, but still a something. Dim and shadowy, I saw it flit across the threshold, while a blast of ice-cold air swept down the room, which seemed to blow through me, chilling my very heart. I was aware of the mysterious presence, and then I heard it speak in a voice like the sighing of an east wind among pine-trees on the banks of a desolate sea.
It said: "I am the invisible nonentity. I have affinities and am subtle. I am electric, magnetic, and spiritualistic. I am the great ethereal sigh-heaver. I kill dogs. Mortal, wilt thou choose me?"
I was about to speak, but the words seemed to be choked in my throat; and, before I could get them out, the shadow flitted across the hall and vanished in the darkness at the other side, while a long-drawn melancholy sigh quivered through the apartment.
I turned my eyes toward the door once more, and beheld, to my astonishment, a very small old woman, who hobbled along the corridor and into the hall. She passed backward and forward several times, and then, crouching down at the very edge of the circle upon the floor, she disclosed a face the horrible malignity of which shall never be banished from my recollection. Every foul passion appeared to have left its mark upon that hideous countenance.
