"It was Violet who hit on the plan. The big thing--the vital thing for her, she pointed out, was to have the necklace in time to give to Musard before he went to London. She said she could easily get out of going to the dance by pretending to have one of her bad headaches, and she did not wish to meet Mrs. Weyne again. Her idea was that I should pretend I had been recalled to France, delay my departure until the afternoon train to prevent suspicion, and return secretly with the necklace. She said that the afternoon train reached London at twenty-five minutes past five, which would give me thirty-five minutes to take a taxi to my flat, get the necklace, and catch the return express at six o'clock. I was to leave the train at Weydene Junction, where nobody was likely to recognize me, and walk across country to the moat-house. She expected that by the time I reached the house the others would have left for the Weynes, so the coast would be clear. I was to enter the house by a little unused door at the back of the left wing which she would leave unlocked for me, and wait at the foot of the staircase until she came down. "I did not like this plan because of the risk, but Violet grew almost hysterical when I objected to it. She said there was no danger, and it was her only chance of safety. She believed that Phil suspected something, because he had looked at her strangely when they were talking about the necklace downstairs. I put that down to nervousness on her part, but I realized she must have the necklace, so I gave in, and said I would do as she wished. I have since bitterly regretted that I did not go openly to London and back, even at the risk of a little idle curiosity. "I announced my recall and departure next morning at the breakfast table, and returned to London by the afternoon train. I drove to Sherryman Street, got the necklace, and returned to Victoria just in time to catch the six o'clock express. I left the train at Weydene, and walked across the fields to the moat-house. It was quite dark when I reached there. I crossed the back bridge over the moat and went to the door in the left wing, as we had arranged. To my surprise it was locked. "I waited outside the door expecting Violet to come down. Everything was silent, so I thought the others must have started for the dance. But the time went on, and nobody came. Then I decided to creep round the, side of the wing and see if there was a light in Violet's bedroom. At that moment I heard a loud scream from somewhere upstairs, followed by a deafening report. "I had no idea what had happened, but I knew that I must not be found there, so I slipped back the way I had come. I ran along the outside of the moat wall, making for the wood in front of the house. As I passed Violet's window I looked up, and it was in darkness. I suppose that was why I did not connect the shot or the scream with her.
