I was so excited when I entered my carriage that I rode all the way home with my bonnet askew and never knew it. When I reached my room and saw myself in the glass, I was shocked, and stole a glance at Lena, who was setting out my little tea-table, to see if she noticed what a ridiculous figure I cut. But she is discretion itself, and for a girl with two undeniable dimples in her cheeks, smiles seldom--at least when I am looking at her. She was not smiling now, and though, for the reason given above, this was not as comforting as it may appear, I chose not to worry myself any longer about such a trifle when I had matters of so much importance on my mind. Taking off my bonnet, whose rakish appearance had given me such a shock, I sat down, and for half an hour neither moved nor spoke. I was thinking. A theory which had faintly suggested itself to me at the inquest was taking on body with these later developments. Two hats had been found on the scene of the tragedy, and two pairs of gloves, and now I had learned that there had been two women there, the one whom Mrs. Boppert had locked into the house on leaving it, and the one whom I had seen enter at midnight with Mr. Van Burnam. Which of the two had perished? We had been led to think, and Mr. Van Burnam had himself acknowledged, that it was his wife; but his wife had been dressed quite differently from the murdered woman, and was, as I soon began to see, much more likely to have been the assassin than the victim. Would you like to know my reasons for this extraordinary statement? If so, they are these: I had always seen a woman's hand in this work, but having no reason to believe in the presence of any other woman on the scene of crime than the victim, I had put this suspicion aside as untenable. But now that I had found the second woman, I returned to it.
