"Then I turned and looked at old Peter, and he looked at me, nodding his head.
"'Let's get out of here!' I said. 'It's no place for any living human to enter, without proper protection.'
"We went out then, and I locked and sealed the door, again.
"After breakfast, I developed the negative; but it showed only the door of the Grey Room, half opened. Then I left the house, as I wanted to get certain matters and implements that might be necessary to life; perhaps to the spirit; for I intended to spend the coming night in the Grey Room.
"I got back in a cab, about half-past five, with my apparatus, and this, Peter and I carried up to the Grey Room, where I piled it carefully in the center of the floor. When everything was in the room, including a cat which I had brought, I locked and sealed the door, and went toward the bedroom, telling Peter I should not be down for dinner. He said, 'Yes, sir,' and went downstairs, thinking that I was going to turn in, which was what I wanted him to believe, as I knew he would have worried both me and himself, if he had known what I intended.
"But I merely got my camera and flashlight from my bedroom, and hurried back to the Grey Room. I locked and sealed myself in, and set to work, for I had a lot to do before it got dark.
"First, I cleared away all the ribbons across the floor; then I carried the cat—still fastened in its basket—over toward the far wall, and left it. I returned then to the center of the room, and measured out a space twenty-one feet in diameter, which I swept with a 'broom of hyssop.' About this, I drew a circle of chalk, taking care never to step over the circle. Beyond this I smudged, with a bunch of garlic, a broad belt right around the chalked circle, and when this was complete, I took from among my stores in the center a small jar of a certain water. I broke away the parchment, and withdrew the stopper. Then, dipping my left forefinger in the little jar, I went 'round the circle again, making upon the floor, just within the line of chalk, the Second Sign of the Saaamaaa Ritual, and joining each Sign most carefully with the left-handed crescent. I can tell you, I felt easier when this was done, and the 'water circle' complete. Then, I unpacked some more of the stuff that I had brought, and placed a lighted candle in the 'valley' of each Crescent. After that, I drew a Pentacle, so that each of the five points of the defensive star touched the chalk circle. In the five points of the star I placed five portions of the bread, each wrapped in linen, and in the five 'vales,' five opened jars of the water I had used to make the 'water circle.' And now I had my first protective barrier complete.
"Now, anyone, except you who know something of my methods of investigation, might consider all this a piece of useless and foolish superstition; but you all remember the Black Veil case, in which I believe my life was saved by a very similar form of protection, whilst Aster, who sneered at it, and would not come inside, died. I got the idea from the Sigsand MS., written, so far as I can make out, in the 14th century. At first, naturally, I imagined it was just an expression of the superstition of his time; and it was not until a year later that it occurred to me to test his 'Defense,' which I did, as I've just said, in that horrible Black Veil business. You know how that turned out. Later, I used it several times, and always I came through safe, until that Moving Fur case. It was only a partial 'defense' therefore, and I nearly died in the pentacle. After that I came across Professor Garder's 'Experiments with a Medium.' When they surrounded the Medium with a current, in vacuum, he lost his power—almost as if it cut him off from the Immaterial. That made me think a lot; and that is how I came to make the Electric Pentacle, which is a most marvelous 'Defense' against certain manifestations. I used the shape of the defensive star for this protection, because I have, personally, no doubt at all but that there is some extraordinary virtue in the old magic figure. Curious thing for a Twentieth Century man to admit, is it not? But, then, as you all know, I never did, and never will, allow myself to be blinded by the little cheap laughter. I ask questions, and keep my eyes open.
"In this last case I had little doubt that I had run up against a supernatural monster, and I meant to take every possible care; for the danger is abominable.
"I turned-to now to fit the Electric Pentacle, setting it so that each of its 'points' and 'vales' coincided exactly with the 'points' and 'vales' of the drawn pentagram upon the floor. Then I connected up the battery, and the next instant the pale blue glare from the intertwining vacuum tubes shone out.
"I glanced about me then, with something of a sigh of relief, and realized suddenly that the dusk was upon me, for the window was grey and unfriendly. Then 'round at the big, empty room, over the double barrier of electric and candle light. I had an abrupt, extraordinary sense of weirdness thrust upon me—in the air, you know; as it were, a sense of something inhuman impending. The room was full of the stench of bruised garlic, a smell I hate.
"I turned now to the camera, and saw that it and the flashlight were in order. Then I tested my revolver, carefully, though I had little thought that it would be needed. Yet, to what extent materialization of an ab-natural creature is possible, given favorable conditions, no one can say; and I had no idea what horrible thing I was going to see, or feel the presence of. I might, in the end, have to fight with a materialized monster. I did not know, and could only be prepared. You see, I never forgot that three other people had been strangled in the bed close to me, and the fierce slamming of the door I had heard myself. I had no doubt that I was investigating a dangerous and ugly case.
"By this time, the night had come; though the room was very light with the burning candles; and I found myself glancing behind me, constantly, and then all 'round the room. It was nervy work waiting for that thing to come. Then, suddenly, I was aware of a little, cold wind sweeping over me, coming from behind. I gave one great nerve-thrill, and a prickly feeling went all over the back of my head. Then I hove myself 'round with a sort of stiff jerk, and stared straight against that queer wind. It seemed to come from the corner of the room to the left of the bed—the place where both times I had found the heap of tossed bedclothes. Yet, I could see nothing unusual; no opening—nothing!…
"Abruptly, I was aware that the candles were all a-flicker in that unnatural wind.... I believe I just squatted there and stared in a horribly frightened, wooden way for some minutes. I shall never be able to let you know how disgustingly horrible it was sitting in that vile, cold wind! And then, flick! flick! flick! all the candles 'round the outer barrier went out; and there was I, locked and sealed in that room, and with no light beyond the weakish blue glare of the Electric Pentacle.
"A time of abominable tenseness passed, and still that wind blew upon me; and then, suddenly, I knew that something stirred in the corner to the left of the bed. I was made conscious of it, rather by some inward, unused sense than by either sight or sound; for the pale, short-radius glare of the Pentacle gave but a very poor light for seeing by. Yet, as I stared, something began slowly to grow upon my sight—a moving shadow, a little darker than the surrounding shadows. I lost the thing amid the vagueness, and for a moment or two I glanced swiftly from side to side, with a fresh, new sense of impending danger. Then my attention was directed to the bed. All the covering's were being drawn steadily off, with a hateful, stealthy sort of motion. I heard the slow, dragging slither of the clothes; but I could see nothing of the thing that pulled. I was aware in a funny, subconscious, introspective fashion that the 'creep' had come upon me; yet that I was cooler mentally than I had been for some minutes; sufficiently so to feel that my hands were sweating coldly, and to shift my revolver, half-consciously, whilst I rubbed my right hand dry upon my knee; though never, for an instant, taking my gaze or my attention from those moving clothes.
"The faint noises from the bed ceased once, and there was a most intense silence, with only the sound of the blood beating in my head. Yet, immediately afterward, I heard again the slurring of the bedclothes being dragged off the bed. In the midst of my nervous tension I remembered the camera, and reached 'round for it; but without looking away from the bed. And then, you know, all in a moment, the whole of the bed coverings were torn off with extraordinary violence, and I heard the flump they made as they were hurled into the corner.
"There was a time of absolute quietness then for perhaps
