"I want you to tell me something about the beginning of your mother's illness," I said, after a pause. "When I saw her two days ago, she scarcely considered herself ill at all--in fact, you were supposed to be the patient." Gabrielle dropped into the nearest chair. "There is a mystery somewhere," she said, "but I cannot make it out. When I came back, after seeing you to-day, mother seemed very restless and troubled. I thought she would have questioned me about being so long away, and ask me at least what I had done with myself. Instead of that, she asked me to tread softly. She said she had such an intolerable headache that she could not endure the least sound. I saw she had been out, for she had her walking boots on, and they were covered with mud. I tried to coax her to eat something, but she would not, and as I saw she really wished to be alone, I left her. "At tea time, our parlour-maid, Peters, told me that mother had gone to bed and had given directions that she was on no account to be disturbed. I had tea alone, and then came in here and made the place as bright and comfortable as I could. Once or twice before, since my father's death, mother has suffered from acute headaches, and has gone to bed; but when they got better, she has dressed and come downstairs again. I thought she might like to do so to-night, and that she would be pleased to see a bright room and everything cheerful about her. "I got a story-book and tried to read, but my thoughts were with mother, and I felt dreadfully puzzled and anxious. The time seemed very long too, and I heartily wished that the night were over. I went upstairs about eight o'clock, and listened outside mother's door. She was moaning and talking to herself. It seemed to me that she was saying dreadful things. I quite shuddered as I listened. I knocked at the door, but there was no answer. Then I turned the handle and tried to enter, but the door was locked. I went downstairs again, and Peters came to ask me if I would like supper. She was still in the room, and I had not made up my mind whether I could eat anything or not, when I heard her give a short scream, and turning round, I saw mother standing in the room in her nightdress. She had the carving-knife in her hand. [Illustration: "IS THERE ANY BLOOD ON MY HANDS?"] "'Gabrielle,' she said, in a quiet voice, but with an awful look in her eyes, 'I want you to tell me the truth. Is there any blood on my hands?' "'No, no, mother,' I answered. "She gave a deep sigh, and looked at them as if she were Lady Macbeth. "'Gabrielle,' she said again, 'I can't live any longer without your father. I have made this knife sharp, and it won't take long.' "Then she turned and left the room. Peters ran for cook, and they went upstairs after her, and I rushed for Dr. Mackenzie."
