Lying on the lower step was a curious instrument. It was a sort of tongs made of steel, about two feet long, and fastened together like a pair of scissors, the joint about five inches from the flattened ends. I carried it to the light and examined it. One end was smeared with blood and short, brownish hairs. It made me shudder, but—from that time on I think I knew. Not the whole story, of course, but somewhere in the back of my head, as I climbed in that hideous quiet, the explanation was developing itself. I did not think it out. It worked itself out as, step after step, match after match, I climbed the staircase. Up to the first floor there was nothing. The landing was bare of carpet. I was on the first floor now. On each side, doors, carefully bolted, led into the house. I opened the one into the hall and listened. I had been gone from the children fifteen minutes and they were on my mind. But everything was quiet. The sight of the lights and the familiar hall gave me courage. After all, if I was right, what could the head on the staircase have been but an optical delusion? And I was right. The evidence—the tongs—was in my hand. I closed and bolted the door and felt my way back to the stairs. I lighted no matches this time. I had only a few, and on this landing there was a little light from the grated window, although the staircase above was in black shadow. I had one foot on the lowest stair, when suddenly overhead came the thudding of hands on a closed door. It broke the silence like an explosion. It sent chills up and down my spine. I could not move for a moment. It was the Frenchwoman! I believe I thought of fire. The idea had obsessed me in that house of locked doors. I remember a strangling weight of fright on my chest and of trying to breathe. Then I started up the staircase, running as fast as I could lift my weighted feet, I remember that, and getting up perhaps a third of the way. Then there came a plunging forward into space, my hands out, a shriek frozen on my lips, and——quiet. I do not think I fainted. I know I was always conscious of my arm doubled under me, a pain and darkness. I could hear myself moaning, but almost as if it were some one else. There were other sounds, but they did not concern me much. I was not even curious about my location. I seemed to be a very small consciousness surrounded by a great deal of pain. Several centuries later a light came and leaned over me from somewhere above. Then the light said: “Here she is!” “Alive?” I knew that voice, but I could not think whose it was. “I’m not—— Yes, she’s moaning.” They got me out somewhere and I believe I still clung to the tongs. I had fallen on them and had a cut on my chin. I could stand, I found, although I swayed. There was plenty of light now in the back hallway, and a man I had never seen was investigating the staircase. “Four steps off,” he said. “Risers and treads gone and the supports sawed away. It’s a trap of some sort.”
