when she heard a shot. She ran in and found him lying on the floor of his dressing-room with his revolver behind him. The governess was still out. The shot had roused the children, and they had come down from the nursery above. She was frantic, but she had to soothe them. The governess, however, came in almost immediately, and she had sent her to the telephone to summon help, calling Sperry first of all, and then the police. “Have you seen the revolver?” I asked. “Yes. It’s all right, apparently. Only one shot had been fired.” “How soon did they get a doctor?” “It must have been some time. They gave up telephoning, and the governess went out, finally, and found one.” “Then, while she was out—?” “Possibly,” Sperry said. “If we start with the hypothesis that she was lying.” “If she cleaned up here for any reason,” I began, and commenced a desultory examination of the room. Just why I looked behind the bathtub forces me to an explanation I am somewhat loath to make, but which will explain a rather unusual proceeding. For some time my wife has felt that I smoked too heavily, and out of her solicitude for me has limited me to one cigar after dinner. But as I have been a heavy smoker for years I have found this a great hardship, and have therefore kept a reserve store, by arrangement with the housemaid, behind my tub.
