She had a golf-stick in her hand, and she said she had found it on the lawn. There was nothing unusual about it, but it occurred to me that a golf-stick with a metal end might have been the object that had scratched the stairs near the card-room. I took it from her, and sent her up for dry garments. Her daylight courage and self-importance, and her shuddering delight in the mystery, irritated me beyond words. After I left her I made a circuit of the building. Nothing seemed to be disturbed: the house looked as calm and peaceful in the morning sun as it had the day I had been coerced into taking it. There was nothing to show that inside had been mystery and violence and sudden death. In one of the tulip beds back of the house an early blackbird was pecking viciously at something that glittered in the light. I picked my way gingerly over through the dew and stooped down: almost buried in the soft ground was a revolver! I scraped the earth off it with the tip of my shoe, and, picking it up, slipped it into my pocket. Not until I had got into my bedroom and double-locked the door did I venture to take it out and examine it. One look was all I needed. It was Halsey’s revolver. I had unpacked it the day before and put it on his shaving-stand, and there could be no mistake. His name was on a small silver plate on the handle. I seemed to see a network closing around my boy, innocent as I knew he was. The revolver—I am afraid of them, but anxiety gave me courage to look through the barrel—the revolver had still two bullets in it. I could only breathe a prayer of thankfulness that I had found the revolver before any sharp-eyed detective had come around. I decided to keep what clues I had, the cuff-link, the golf-stick and the revolver, in a secure place until I could see some reason for displaying them. The cuff-link had been dropped into a little filigree box on my toilet table. I opened the box and felt around for it. The box was empty—the cuff-link had disappeared! CHAPTER V. GERTRUDE’S ENGAGEMENT At ten o’clock the Casanova hack brought up three men. They introduced themselves as the coroner of the county and two detectives from the city. The coroner led the way at once to the locked wing, and with the aid of one of the detectives examined the rooms and the body. The other detective, after a short scrutiny of the dead man, busied himself with the outside of the house. It was only after they had got a fair idea of things as they were that they sent for me.
