"When I came to myself," she continued, "I was back in Madame's house next door. She had forced some liquid between my lips, and was injecting some other fluid into my arms with a hypodermic syringe. I was amazed, too, to notice that she had changed her dress, assumed a grey wig, and wore a cap with bright ribbons, in most marvellous imitation of an old lady. While I thus remained on the couch in the back sitting-room, dazed and only half conscious, there came a loud ring at the door and I overheard a police-officer making inquiries of `Mrs. Luff' regarding the people next door. Then I knew that Kerr's body had been discovered, and that Madame was personating the previous occupier of that house. I was not, however, aware at that time of how Hartmann had called upon Madame and had carried Mrs. Kerr through a small breach made in the fencing of the garden at the rear into her own house, or that I had been brought back by the same way into ours. Madame, when all was clear, went that night down to The Hollies, leaving me alone with the servants, who, having apparently been sent out upon errands during the events described, knew nothing. I therefore kept my own counsel, and recollecting having overheard Blain, when taking leave of Madame on his last visit, refer to an appointment he had with Hartmann in St. James's Park, I resolved also to keep it. I did, but instead of meeting him," she said, addressing me, "I met you." "I recollect the meeting well," I answered. "Continue." "Well, I returned to The Hollies, but it was evident from Madame's manner that she was in deadly fear. I was not, of course, aware of what had actually occurred, although I entertained the horrible suspicion that both my friends had fallen victims. She took me partly into her confidence later that day, for the police, she said, would discover an `awkward accident' next door, and that she must not be seen and recognised as Mrs. Luff. She told me that, in order to avoid any unpleasant inquiries, Hartmann had entered the place before the police, and had carried away every scrap of anything that could lead to their identity, and as I knew from Mr. Kerr's previous conversation that all his letters were addressed to Drummond's Bank, it seemed improbable that the bodies would be identified. `It's a very serious matter for us,' Madame said to me earnestly. `Therefore say nothing, either to Mrs. Blain or Mary.' By that, and other subsequent circumstances, I knew that both were in ignorance. They had no hand whatever in the ghastly affair, for after the quarrel they never again met Madame.
