Having once followed me, it seemed thenceforth to take up quarters in my house, at least for the evening and morning hours of the day, and strange as it was, I soon learned to regard the presence of a third person as an established fact; indeed, I came to believe that in some instances a faint breathing might be detected. Nevertheless I would not leave anything to the possibilities of imagination, but was always experimenting, with a view to prove still more clearly that there was no illusion possible. To this end a brass and steel rod, fitted between the floor and a projection from the wall, was connected with an indicator which moved in a large arc when the slightest touch shook the floor. By this means my ears were reinforced by sight.
I also began systematically to conceal from the unknown guest the fact that I suspected its presence; but at last the point was reached where, to protect my own reason, it must be settled whether it was all a series of illusions or a sober truth.
For by dint of thought a scheme had been perfected, and on a Sunday morning, when as usual Rachel had disappeared, no man has ever known whither; when, according to its custom, the strange visitant had also, to all appearance, withdrawn,—on a Sunday morning I hastened to put my plan in action. On the main floor in the rear of the house was a chamber, into which the sounds had sometimes intruded, which was small, bare, and lighted by one deep window looking directly out on the orchard. This window I had grated strongly with heavy wire on the outside, where the orchard hill rose steeply from the house; and over against the window, in the wall between chamber and dining-room, was a high closet, in which I had stored a strong net, such as fishermen use for their seines. Fastening stout wires to the ceiling from one end of the room to the other, to be used for slides, and rigging several small blocks above the window and near the floor, I stretched the necessary ropes from closet to blocks and back again, laid everything ready for instant use, cleared the room of furniture, and awaited events.
There was no fear of interruption from Rachel, for during the years we had lived together I had never seen her on a Sabbath. Every Monday she was at her post, although laboring under some excitement, which showed itself in mutterings and a certain wild gesture that I had learned to attach no importance to. There was no fear that I should not have the invisible to myself.
Evening came to close a sultry day with growls of distant thunder and sudden flares of light behind Navesink Hills; the bushes drooped languidly; only the tree-toads were clamorous, and their jubilee was a mournful one on every side. I was sitting by the west window with my head on my breast, and, now that the crisis had come, almost apathetic to the presence itself, when its approach took place. It seemed to stop near my chair, as if it regarded me closely. I had been before in singular predicaments, but it seemed to me this was the most trying. I felt that I must look very pale, but with an affectation of indifference I arose, walked across the room and entered the bed-chamber. In a moment I understood that the unseen had likewise passed the sill and had entered the room; then I slammed the door, locked it, and put the key in my pocket.
Everything had been made ready to cope with a material and not a supernatural being; still it was purely a venture, and at no previous time had there seemed so little hope of success. Nevertheless not a moment was lost in hauling out the net and placing it in position across the room so that it hung straight, filling the space between wall and wall, and ceiling and floor. Then I began to draw it down the room by means of the ropes, and on the axis of the chamber, so that its edges passed smoothly along ceiling, walls, and floor. The anxious moment was at hand.
All the running gear had to be worked evenly; at the same time every nerve was strained in order to detect the slightest bulge in the upright net, should it come in contact with a tangible body.
Until three quarters of the room had been sifted nothing occurred. Then I saw the edge against the left-hand wall carefully drawn aside; to spring forward and close the opening was the instinctive work of a second. Terror combining with a fierce delight lent me an extraordinary force; I drew with convulsive power on the ropes. Every moment an invisible hand seemed to lift the net at some point, but each attempt was luckily frustrated. At last the movements ceased, and I drew the net flat against the farther wall. With feverish haste my hand travelled over its entire surface; the net was scanned in profile for the impression of a body, but there was none. The game had either escaped or withdrawn into the deep window-seat.
Now came a moment for breath, and for reflection. Again the cynical cloud of doubt folded me in. Dupe of my own morbid imagination, I should stand convicted of monomania in the eyes of any reasonable being who should see my actions. Then it was best, was it not? to tear the net away; or should I deliberately pursue to the utmost a plan begun? Never before had I so clearly felt a dual existence urging to opposite courses of action, as if the body’s instinct commanded an advance, while the mind, assailing the whole proceeding with ridicule, was for giving up the game. But for all that it was a good sign that I began to feel a slight awe at the near possibility of a discovery. For I retreated to the door, unlocked it, and stood irresolute; then returned again to the window, without strength to come to a decision.
But while I pondered, a low, chuckling noise startled me, and Rachel stood by my side, erect and with features full of energy, her dull eyes blazing, and her short straight hair tossed about; in her hand she brandished with exultation a carved rod hung with bright claws and shells, with lappets of fur and hair; and at her and it I gazed with speechless amazement. Had she too gone mad? She took a few steps, as if in a rude dance, and shook the stick, and while her eyes glared into mine she nodded her head to the time.
