So on this summer night, while distant thunder rumbled, I left a silent motor-car and tramped with two armed companions up the mound-covered reaches of Tempest Mountain, casting the beams of an electric torch on the spectral gray walls that began to appear through the giant oaks ahead. In this morbid night solitude and feeble shifting illumination, the vast boxlike pile displayed obscure hints of terror which day could not uncover; yet I did not hesitate, since I had come with fierce resolution to test an idea. I believed that the thunder called the death-demon out of some fearsome secret place; and be that demon solid entity or vaporous pestilence, I meant to see it. * * * * * I had thoroughly searched the ruin before, hence knew my plan well; choosing as the seat of my vigil the old room of Jan Martense, whose murder looms so great in the rural legends. I felt subtly that the apartment of this ancient victim was best for my purposes. The chamber, measuring about twenty feet square, contained like the other rooms some rubbish which had once been furniture. It lay on the second story, on the southeast corner of the house, and had an immense east window and narrow south window, both devoid of panes or shutters. Opposite the large window was an enormous Dutch fireplace with scriptural tiles representing the prodigal son, and opposite the narrow window was a spacious bed built into the wall. As the tree-muffled thunder grew louder, I arranged my plan's details. First I fastened side by side on the ledge of the large window three rope ladders which I had brought with me. I knew they reached a suitable spot on the grass outside, for I had tested them. Then the three of us dragged from another room a wide four-poster bedstead, crowding it laterally against the window. Having strewn it with fir boughs, all now rested on it with drawn automatics, two relaxing while the third watched. From whatever direction the demon might come, our potential escape was provided. If it came from within the house, we had the window ladders; if from outside, the door and the stairs. We did not think, judging from precedent, that it would pursue us far even at worst. I watched from midnight to 1 o'clock, when in spite of the sinister house, the unprotected window, and the approaching thunder and lightning, I felt singularly drowsy. I was between my two companions. George Bennett being toward the window and William Tobey toward the fireplace. Bennett was asleep, having apparently felt the same anomalous drowsiness which affected me, so I designated Tobey for the next watch although even he was nodding. It is curious how intently I had been watching that fireplace.
