"If I had she would only have used a smaller knife. Well," continued Miss Gordon, "on that fatal night Laura was particularly angry with Edgar because she had been informed by Rudolph that he was flirting with Polly Horley. However, I managed to soothe her, and, as Rudolph never came for me as he promised, I left this house for the station a few minutes after eleven. When I got near the station I found that I had forgotten my purse and returned for it; then, Dr. Ellis," said Janet, clasping her hands, "I came on a terrible sight. Edgar was lying dead on the path, and Laura was lying beside him. The moon showed at intervals, so I saw all quite plainly. Finding Edgar was dead I thought Laura had murdered him, especially as the carving-knife lay on the path beside her. Laura revived very soon, and said she had not killed Edgar. I dragged her into the house; but picking up the carving-knife she said it was the cause of all, and threw it behind some laurels. I had no time to look for it, as my sole object was to get Laura away. I made her put on my hat and cloak and take my purse, telling her to go to Mrs. Amber's and remain in her bedroom, and that I would impersonate her and see the matter through. Laura was beside herself with terror, saying that she was innocent; but she had wit enough to see her danger if she stayed. Therefore, she braced herself up and went away to take a cab to Pimlico. She got one and arrived at Geneva Square safely." "Yes, and remained in her bedroom as you told her. Mrs. Amber informed me of that. And you, Miss Gordon?" "I," said Janet, simply, "assumed my sister's character and ran round to call you to see the corpse. You know the rest." CHAPTER XVIII WHAT REALLY HAPPENED After Janet had finished her history there ensued a short silence. Ellis was lost in admiration at the wonderful pluck and resolution of the girl, which had enabled her to face and carry through a difficult matter for the sake of her weaker sister. Now that the worst was over--since she had rescued Laura Moxton from the ordeal of a public accusation--Janet seemed to be in danger of breaking down. After the tension of nerve and will came the inevitable relaxation. The impulse of Ellis was to take her in his arms, and comfort her with assurances of love and protection. But the time was not yet ripe for him to speak of his personal feelings. There was much to do, much to be learnt, before the crooked could be made straight; therefore Ellis, sacrificing self, began to question Janet on points which did not seem quite clear to him. At his first remark she braced herself and gave him immediate attention. "If you thought that your sister had killed Moxton, why did you not hide the carving-knife?"
