"I kept up the error. I demanded money as my right, and from his words I gathered that the Frazers had been at their old tricks and defrauded another relative." Robert started. "Do you hear?" he murmured to Brett. "That accounts for Alan's strange reception of me the same day." Brett held up a warning hand. Ooma was still talking. "I taunted him with thriving on the plunder of his own people. That made him furious. He raved about the world being in league against him. The only relative he loved, one who was more than brother, had stolen the woman he wished to marry; his sister was a living lie; his cousin a blackmailer. I laughed. 'Do you disown your sister, then?' I asked. He took from his breast-pocket some papers--you will find them there, on the table--and told me, in great anger, that he possessed proof that she was not his sister. I was cooler than he, and saw the value of this admission. I pretended to go away, but hid among the trees and saw him walk about the library for nearly an hour. I meant to enter the house if an opportunity presented itself, and, trusting to my appearance, go to his bedroom, if he changed his clothes and went out. But he helped me by placing the papers in the drawer which I afterwards broke open. I saw him meet you"--he feebly pointed to Robert. "I saw you arrive in the carriage," and he indicated David. "Then I determined to wait until the night. I went back to Stowmarket, where I left a portmanteau at a small hotel"--Brett knew that Winter stole a look at him, but he ignored the fact--"and changed my clothes. In England, at night, a man in evening dress can enter almost any house. When I returned I carried my bag with me, as I did not know how I might wish to get away subsequently. I saw the preparations for the ball. They helped me. David Hume's unexpected appearance at midnight upset my plans. Waiting near the gate, I witnessed Alan's meeting with a girl in a white dress. Whilst they were talking, I ran up to the house and found David asleep in the library. I resolved to act boldly. Even he would not know what to do if he suddenly discovered another Frazer in the room. To force open the drawer I picked up the Japanese sword, and knew it as belonging to my house by the device on the handle of the Ko-Katana. The thing inspired me. I obtained the papers, and was going out when I met Alan. He had seen what I was doing. He called me a cur, and the memory of my ancestor's vengeance rushed on me, so I struck him with the knife, and left it resting in his heart as he fell. Afterwards it was easy. No one knew me. Those who had seen me thought that I was either David or Robert Hume-Frazer. I depended on the police and the servants to complete the mystery. They did. I saw David meet the same girl in a white dress near the lodge, so I sent the post-card which I made Jiro write for me. He wrote it badly, which was all the better for my purpose. I meant David to be hanged by the law; then I would marry Margaret.
