He interrupted him, saying quickly: "Yes. I went to see Lady Loudwater. I thought it likely that she would attach a good deal more importance to Loudwater's silly threats than they deserved and might be worrying. It would have been quite natural. I wanted to talk it over with her and set her mind at rest about it. It didn't take very long to do that, partly because it was a long time since he had really frightened her. She had got used to his tantrums and bullying; and even this new game had not disturbed her very much. We both came to the conclusion that he was just blustering again, and wouldn't do anything. As a matter of fact, I don't think she cared very much what he did. She had got so fed up with him that she didn't care whether they separated or not." Mr. Flexen felt more sure than ever that this garrulity was unusual in Colonel Grey. He was talking with a purpose, apparently to induce him to believe that both he and Lady Loudwater had taken her husband's threat of divorce proceedings lightly. He began to think that they had not taken it lightly at all, or, at any rate, one or other of them had not. "Yes," he said. "That's what always happens with those blustering fellows. In the end no one takes them seriously. But what I came to ask you was: Did you, as you came through the library or went out through it, hear Lord Loudwater snore?" Colonel Grey hesitated, just as Lady Loudwater had hesitated over that question. Plainly he was weighing the effect of his answer. Then he said: "No." Mr. Flexen's instinct assured him that Colonel Grey had lied just as Lady Loudwater had lied. "Are you sure that nothing in the nature of a snore came to your ears as you came out? Did you hear any sound from the room? You can see how important it is to fix as near as we possibly can the hour of Lord Loudwater's death," he said earnestly. "No, I heard nothing," said Colonel Grey firmly. "Bother!" said Mr. Flexen. "It's very important. Possibly I shall be able to find out from some one else." "I hope you will," said Grey politely. Mr. Flexen bade him good-night cordially enough, and drove back to the Castle in a considerable perplexity. Both Colonel Grey and Lady Loudwater were behaving in an uncommonly odd, not to say suspicious manner. He was quite sure that both of them had lied about the dead man's snoring. But it was plain that either had lied with a different object. Lady Loudwater had lied to make it appear that her husband had been alive at midnight. Colonel Grey had lied to make it appear that he was dead at a quarter-past eleven. But Mr. Flexen was sure that Colonel Grey had heard Lord Loudwater snore and that Lady Loudwater had not. What did they know? What had they done? Or what had one of them done? CHAPTER IX When Mr. Flexen reached the Castle Wilkins took him to a bedroom in the west wing. He found that his portmanteau had arrived, had been unpacked, and that his dress clothes were laid out ready for him on the bed.
