"She slipped upstairs to see me as soon as she dared. She was greatly relieved when she learnt that I had not parted with the necklace, and she wanted me to go up to London and bring it back so that she could wear it to the party. I was willing to do so, but I doubted whether I would be able to get back in time. The local train service had been restricted on account of the war, and the only train I could catch back did not reach Heredith until half-past seven.
"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.
"I plunged through the woods till I came to the carriage drive. From there the front of the moat-house was visible to me. I could see lights flashing, and people moving hurriedly about. After I had stood there for some time I saw a man hurrying across the moat-house bridge in my direction, so I went back into the wood and hid behind a tree. The man stopped as he walked along the carriage drive, and looked towards the tree where I was crouching. He called out 'Who is there?' I recognized his voice. It was Tufnell, the butler. I thought I was discovered, and crept into some undergrowth, but in a moment he walked on.
"I remained hidden in the undergrowth for some time—an hour or more. Once I heard footsteps crunching on the gravel-path, then all was silent again. After waiting for some time longer I decided to walk back to Weydene and return to London. But I made such a wide detour for fear of being seen that I lost my way, and it was nearly midnight when I found myself at Rainchester, on the main line, just in time to catch the last train to London.
"It was a terrible shock to me when I opened my paper the next morning and read about poor Violet's murder. I had never thought of anything like that. At first I could think of nothing but her terrible end, but then it occurred to me that my own position would be awkward if the loss of the necklace was discovered. As the papers said nothing about the necklace I concluded that it had not been missed. But I knew the police would be searching for clues, and might discover the loss at any moment. I knew it was dangerous for me to keep it in my possession, so I decided to get rid of it without delay.
"I thought at first of returning it anonymously, but I immediately abandoned that idea as too dangerous. Then I thought of dropping it into the river. It occurred to me, however, that if by any chance the police discovered that the necklace had been given to me, and I couldn't produce it if I were questioned, I should be in a worse fix still. So I tried to think of a safe hiding-place where I could lay my hands on it in case of necessity. I could think of none. Time went on, and before I had decided what to do with the thing my man came along and said it was time to catch the boat train. So in the end I put the necklace into my pocket and took it to France with me. It seemed as safe there as anywhere else for the time being.
