"The best place she could be, George. The girl is a born idiot from what I saw of her. However, you know why I renewed the year-by-year lease. Where the confession is I have no idea; but the person who holds it will certainly make use of it some day to extort money, and then we will learn who killed Mrs. Jersey." "I dare say. The assassin must have taken the papers. Well?" Derrington proceeded with his account of his doings on that night. "As I said, I went to see Bawdsey at his rooms. I took a cab, and as the fog was thick I had considerable difficulty in finding the place. The rain and fog chilled me, for I am not so young as I was, and when I arrived I was shivering. But I was too anxious to tell Bawdsey about Mrs. Jersey, to trouble. He heated some water to give me a glass of hot whisky. While the water was boiling I told him, I was going to see Mrs. Jersey. He asked me how I could get into the house without being admitted by one of the servants and thus run a chance of my visit being known." "Did it never strike him that Mrs. Jersey expected you and would admit you when you rang?" "Yes, it did strike him; but he knew that I didn't want any one to know that she had a visitor so late at night." "I don't know why you took all these precautions, sir." Derrington smiled dryly. "Perhaps they were rather unnecessary, but I thought it best to be on the safe side. As a matter of fact, I had a latch-key." "I thought that Mrs. Jersey never allowed latch-keys." "This one came to me when I bought the house, and was given to me by the agent. I told Mrs. Jersey I had it and that I would let myself in. She expected me at eleven." "I know she did," said George, "for on that night she asked the boarders to be in bed by eleven, and broke up her party at ten. I wondered if she was having any one to meet her then." "She was expecting me. It was after ten when I told Bawdsey, and I explained to him that I had a latch-key. He gave me the whisky, and, being chilled, I drank it. Then I fell asleep." George looked up suddenly. "The whisky was drugged," he guessed. "It was," assented Derrington, "and while I was insensible Bawdsey took the latch-key out of my pocket and put on my coat. He is rather my height, so with that and the fur coat I expect he passed himself off as me to Mrs. Jersey until she saw his face." "When she did, she would have nothing to do with him. Although," added George, "he was an old boarder in the house." "Wait till I tell you the rest," said Derrington, "and then you can give an opinion. When I woke it was after twelve. I never suspected that the whisky had been drugged, and thought that it was some sort of illness. Bawdsey was in the room when I awoke. He did not tell me that he had been to Mrs. Jersey, and I now saw that it was too late to go. He advised me to see her on the morrow, saying that it was doubtful if you would speak to her on that night."
