yours has been set to watch this house for ten days," he said. "Was that by your order?" I was so completely taken aback by his discovery that I sat for a moment dumfounded, and gave him no answer. He, however, seemed trembling with passion. "Was it by your orders?" he asked again, standing over me and almost hissing out his words. "It was," I answered after a pause; "but, you see, circumstances were suspicious." "Suspicious! Then you did believe me to be a rogue. I have shot men for less." I attempted to explain, but he would not hear me. He had lost command of himself, stalking up and down the room with great strides until the temper tautened his veins, and his lean hands seemed nothing but wire and bones.

I had him gripped about the waist with my left arm, my right clutching the hand wherein he held the pistol. He, in turn, put his left hand upon my throat and threw his
