“‘I’ll tell you exactly what happened as far as I know the facts,’ I said. ‘Lady Granger and her husband had a very bad quarrel to-night. Then she came to bed, and so did I. Shortly afterwards her husband came along into this room. Now, my bedroom is in the passage you have just come along, and about ten minutes after Sir Henry came in here, his wife followed him. I opened my door, because I was afraid they might start quarrelling again, and he had been drinking. I saw her come in; there was a pause, and then a revolver shot rang out.’ “‘Was this door shut?’ he snapped. “‘Yes,’ I answered, ‘it was. I rushed along the passage and came in. I found her standing, with the revolver at her feet, staring at her husband, who was lying where he is now. She said: ‘There’s been an accident.’ And then she muttered something about a man and the window before she fainted. I went to the window, and there was no one there. I looked out; will you do the same?’ “I waited while he walked over and looked out, and after what seemed an interminable time he came back again. “‘How long was it after the shot before you looked out?’ His voice was very low as he asked the question. “‘Not a quarter of a minute,’ I answered, and we both stood staring at one another in silence. “‘Good God!’ he said at length, ‘what are you driving at?’ “‘I’m not driving at anything, Sir Edward,’ I answered. ‘At least, I’m trying not to drive at it. But the man is dead, and the police must be sent for. What are we going to say?’ “‘The truth, of course,’ he answered instantly. “‘Quite,’ I said slowly. ‘But what is the truth?’ “He turned very white, and leant against one of the old suits of armour, of which the dead man had a wonderful collection all over the house. “‘Did Lady Granger see this man go out of the window?’ he asked at length. “‘No, she only heard him open it. You see, she says he switched off the light. It was on when I rushed in.’ “‘A rope,’ he suggested. “‘Impossible in the time,’ I said; ‘utterly impossible. Such a suggestion would be laughed out of court.’ “He came over and sat down heavily in a chair, and his face was haggard. “‘Sir Edward,’ I went on desperately, ‘the doctor will be here shortly; the police must be sent for. We’ve got to decide something. This man didn’t go out by the door or I’d have seen him; only a fly could have gone out by the window. We’ve got to face the facts.’ “‘You don’t believe there was a man here at all,’ he said slowly. “‘Heaven help me! I don’t,’ I answered. ‘It’s all so easy to reconstruct. The poor girl was driven absolutely desperate by what happened to-night, and by the last thing he said to her after their quarrel.’ I looked at him for a moment before going on. ‘He accused her of being in love with you.’ I said it deliberately, and he caught his breath sharply.
