"Would you mind describing to me, as far as you are able, what you heard in the night?" I said. "I have a reason for asking this. No doubt you have already several times told your story." "Yes. To the medical men and also to the police," he said. "Well, it was like this. I'm quartered at Canterbury, and Guy, who was in my regiment and retired a year or so ago, asked me to spend a few days with him. I came here three days ago and found him in the highest of spirits, and very keen about tennis. He took me over to see a man named Shaw, and his daughter, of whom he was, I know, very fond. The night before last he gave a little dinner to a few people, and Shaw and the girl were here. After dinner we all went out on to the lawn for coffee. The place was hung with Chinese lanterns and looked charming, but all Guy's attention was devoted towards entertaining Shaw's daughter. I saw them cross the lawn in the moonlight and stroll into the grounds together; and when they came back I overheard Shaw expressing his annoyance to her at her absence. Shaw chatted with Justice Michelmore a good deal, while I had a Mrs Vane, a rather stout person, put upon me for the evening. I tell you I envied Guy, for the girl is really delightful." "Was there any bridge?" "Yes, for about an hour in the drawing-room. Shaw and the Judge did not play. Before eleven the guests began to depart, and the Vanes, the last to leave, went about midnight. After they had gone I sat in the library with Guy for half an hour, and had a cigar. He was full of Asta Seymour, and when I asked him why he did not propose to her he reflected a moment, and then told me, in strict confidence, that he would do so at once--but for a certain circumstance." "Did he explain that circumstance?" I asked eagerly. "No. I pressed him, but he refused to tell me. `It is my secret, Teddy,' he said. `A secret which, alas! bars my happiness for ever.' As we smoked, I noticed that, contrary to the rule, the long window yonder was open, and remarked upon it. He rose, and saying that the servant had probably forgotten it, closed it himself and barred the shutters. You'll see they are strong shutters, and they were found in the morning closed and barred just as he had left them. Indeed, I unbarred them myself." "Then you left him here?" I asked. "No. He turned off the light and came out with me, locking the door after him, for it seems he's always careful to have every door on the ground floor locked at night. He came upstairs with me, wished me a cheery good-night outside my own door, and, promising to motor me into Oakham on the morrow, went along to his room. That is the last time he was seen alive." "What did you next hear?"
