"Yes, he met Malet, and told him that his victim was dead. Malet grossly insulted Robert, and there was a quarrel. Unable to restrain his anger, Robert threw himself on Malet, but being an old man and feeble, he was easily overpowered and thrown to the ground. Robert told me this, and I believe it is the truth, because I found his crape scarf was torn--no doubt in the struggle. Malet left him lying on the wet grass and went off. He must have been shot almost immediately afterward."
"By whom?" asked Van Zwieten, keenly.
"Ah! that is the question. I have my suspicions, but I may be wrong. But when Brenda came home with the news of a murder I guessed that the victim was Malet. The servants came to my study door and found it locked. Robert was with me then, and I had locked the door because I did not want him to be seen. They thought it was you I was talking to, and I said it was you. When afterward you came in by the front door they knew, of course, that I had lied. Brenda asked me about that, and I still declared that you had been with me, but that you had gone out of the study window to the front door. I told her also that I was the man seen by Harold Burton."
"Why did you do that?"
"Can't you guess? To save Robert. He had a grievance against Malet, he had been struggling with him, and there was every chance that he might be accused of the murder. There was only my evidence to prove his alibi, and as I was his brother I dreaded lest my word should be insufficient. While the servants were with Brenda in the kitchen I went back to my study, put a coat of my own on Robert, and gave him a soft hat to pull down over his eyes. Then I gave him money, and told him to catch the ten-thirty train from Chippingholt to Langton Junction."
"Which he did," said Van Zwieten. "I was watching all that business through your study window. I followed Robert, wondering who he was, and watched him go off by the train. Then I came home to the house and was admitted, as you know."
"Why did you not speak to me?"
"It was not the proper moment to speak. I did not know who Robert was, and until I entered the house I knew nothing about the murder. I also guessed the victim was Malet, and I thought you must have hired this man to kill him, and having finished with him, had got him safely out of the way."
"Ah! you were anxious to trap me!" cried Mr. Scarse, angrily. "Well, you know the truth now, and you can do nothing. I burned the crape scarf and I told Brenda I was the man Harold had seen. If you choose to make a scandal, I shall tell my story exactly as I have told it to you, and prove Robert's innocence. At the worst he can only be put under restraint again."
"I don't wish to make any scandal," said the Dutchman, mildly, "more especially seeing that your daughter is to be my wife. You can rely on my silence if only on that account. But I'm glad I have heard this story now. I want to know who killed Malet."
