“Doctor, men of your calling are the same as confessors, are they not?”

“If you mean as regards the sanctity of professional communications, yes.”

“Then I should like to confide a few things to you under the seal of that professional secrecy.”

“All right; go ahead.”

“Do you know that my wife is from Chicago?”

“Yes.”

“I have never been there myself, and consequently know none of her friends. You may have heard that my father was very much opposed to my marriage. He collected a lot of cock-and-bull stories about my wife, which, needless to say, I did not believe. So the wedding took place, and, until a week ago, I can truthfully say that I have been perfectly happy.”

“What happened then?”

“I had to go out of town for two days on business, and got back very late on Wednesday night, having been delayed by an accident on the line. I was careful to be very quiet as I let myself in, anxious not to wake up my wife, who, I expected, would be fast asleep at that hour. I was therefore surprised and pleased to find the hall still ablaze with light. So, she had sat up for me after all, I thought. Taking off my hat I turned to hang it on the rack when I noticed a strange hat among my own. I took it down and examined it. It contained the name of a Chicago hatter and the initials A. B. were stamped on the inside band. At first I was simply puzzled, then it occurred to me that its owner must be still on the premises. That thought roused all my latent jealousy, so, putting the hat quietly back, I stole on tiptoe to the parlor. Peeping through the portières, I saw my wife lying asleep on the sofa. She was quite alone. To whom then did the hat belong? What man had left in such hurry or agitation as to forget so essential a thing? All the stories my father had told me came back to me with an overwhelming rush. Then I blushed at my want of confidence. All I had to do, I assured myself, was to wake up my wife and she would explain everything at once. I should not need to ask a question even; she would of her own accord tell me about her visitor. Full of these hopes I entered the room. She opened her eyes almost immediately and greeted me with even greater warmth than usual. I responded as best I could, but my impatience to hear what she had to say was so great as to render me insensible to everything else. I soon led our talk round to what she had been doing during my absence. She told me in a general way, but, Doctor, she made no mention of a gentleman visitor! I think I was patient. Again and again I gave her the chance to confide in me. At last, I asked her right out if she had happened to see any of her Chicago friends. She hesitated a minute, then answered, deliberately, No! To doubt was no longer possible. She was concealing something from me; therefore, there was something to conceal. And yet she dared to hang around my neck and nestle close to me. It made me sick to feel the false creature so near. I don’t know what came over me. The room swam before my eyes, and starting to my feet I flung her from me. She fell in a heap by the window and lay quite still, staring at me with speechless terror. I had had no intention of hurting her and was horrified at my brutality. I went to her and tried to raise her up, but at my approach she shrieked aloud and shrank away from me. I was thoroughly ashamed now and begged her to forgive my behaviour. But for some time she only shook her head, till at last, overcome by her emotions, she burst into hysterical sobs. This was too much for me. I forgot everything except that I loved her, and, kneeling down, gathered her into my arms. She no longer resisted me, but like a tired child let 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?”
