me do with her what I would. I carried her upstairs and soon had the satisfaction of seeing her fall asleep. From that day to this neither of us has ever referred to this occurrence! I didn't, because--well, my motives were very mixed. In the first place, I couldn't apologize for my behaviour without telling her the reason first, and that I was unwilling to do unasked. I was ashamed of my suspicions, and wanted the explanation to be offered by her and not solicited by me. And then, underlying everything, was an unacknowledged dread of what I might discover, and terror that I might again forget myself. But what were her reasons for never asking for the meaning of my conduct? Why did she not make me sue on my knees for pardon? She has always made a great fuss whenever I have offended her before; why did she pass over this outrage in silence? Did she fear what questions I might ask? Did she suspect the cause of my anger? That night, before going to bed, I took that accursed hat and flung it out of the dining-room window. It fell to the court below, and there Argot must have picked it up." "When did you first become convinced that that hat had belonged to the murdered man?" "Not for several days. In fact, I have never been perfectly sure till this evening." "Really?" "Yes; you see it did not occur to me for some time that there was any connection between my wife's visitor and the--the victim." Here the poor fellow shuddered. "Her manner was slightly constrained, and I saw she was depressed, but I thought that a natural result of the coolness that had arisen between us. I soon found out, however, that although our strained relations might weigh on her somewhat, the chief cause of her trouble was the murder. She hardly ever spoke of it, but I could see that it was never out of her mind. She used to send out for all the papers and pore over them by the hour, and was so nervous that it was positively painful to be in the room with her. She would start and scream with or without provocation. Another peculiarity she developed was an extreme disinclination to leaving the house. She went out on Thursday afternoon, I believe, but from that day to the time of Argot's arrest I don't think she ever left the building unless I insisted on it. And another queer thing she did, was to stand behind the curtains and peer at your house. I would catch her doing this at all hours of the day and night. Then I began to wonder more and more why this murder had such an effect on her. I read and re-read all that was printed about it, and suddenly it came to me that no hat had been found with the body. I searched the papers again feverishly. I had not been mistaken. Every article of clothing was carefully enumerated, but no hat was mentioned. It was then I first suspected that the dead man and my wife's visitor were one and the same person. It was an awful moment, Doctor."
