"_I_ broke it off!" said Elizabeth angrily, and she drew herself up very stiff and frowning.

It was Mr. Flexen's turn to hesitate. Then he made a shot, and said: "I see. He wanted you to become engaged to him again, and you wouldn't."

Elizabeth looked at him with an air of surprise and respect, and said: "It wasn't quite like that, sir. I didn't say as I wouldn't be his fioncy again. I said I'd see how he behaved himself."

"Then he wasn't in a good temper," said Mr. Flexen.

"He was in a better temper than he'd any right to expect to be," said Elizabeth with some heat.

"That's true," said Mr. Flexen, smiling at her. "But after the trouble he had had with Lord Loudwater he couldn't be in a very good temper."

"He was too used to his lordship's tantrums to take much notice of them.

He was too much that way himself," said Elizabeth quickly.

"I see," said Mr. Flexen. "What time was it when he left you?"

"I can't rightly say. But it wasn't half-past eleven," she said.

He perceived that that was true. At the moment there was no more to be learned from her. If she could throw any more light on the doings of James Hutchings, she was on her guard and would not. But he had learned that James Hutchings had not entered the Castle by the side door. Had he entered it and left it by the library window?

He asked Elizabeth a few more unimportant questions and dismissed her.

Inspector Perkins, having sent a groom to inform the coroner of the murder, and of the need for an early inquest into it, came back to him.

They discussed the matter of James Hutchings, and decided to have him watched and arrest him on suspicion should he try to leave the neighbourhood. The inspector telephoned to Low Wycombe for two of his detectives.

Mr. Flexen questioned the rest of the servants and learned nothing new from them. By the time he had finished the two detectives from Low Wycombe arrived, and he sent them out to make inquiries in the village, though he thought it unlikely that anything was to be learnt there, unless Hutchings had been talking again.

He had risen and was about to go to the smoking-room to look round it again, on the chance that something had escaped his eye, when Mrs.

Carruthers, the housekeeper, entered the room. None of the servants had mentioned her to him, and it had not occurred to him that there would of course be a housekeeper.

"Good morning, Mr. Flexen. I'm Mrs. Carruthers, the housekeeper," she said. "You didn't send for me. But I thought I ought to see you, for I know something which may be important, and I thought you ought to know it, too."

"Of course. I can't know too much about an affair like this," said Mr.

Flexen quickly.

"Well, there was a woman, or rather I should say a lady, with his lordship in the smoking-room last night--about eleven o'clock."

"Indeed?" said Mr. Flexen. "Won't you sit down? A lady you say?"

"Yes; she was a lady, though she seemed very angry and excited, and was talking in a very high voice. I didn't recognize it, so I can't tell you who it was. You see, I don't belong to the neighbourhood. I've only been here six weeks."

"And how long did this interview last?" said Mr. Flexen.

"I can't tell you. It was no business of mine. I was making my round last thing to see that the servants had left nothing about. I always do. You know how careless they are. I went round the hall, and then I went to bed. But, of course, I wondered about it," said Mrs. Carruthers.

Mr. Flexen looked at her refined, rather delicate face, and he did not wonder how she had repressed her natural curiosity.

"Can you tell me whether the French window in the library, the end one, was open at that time?" he said.

"I can't," she said in a tone of regret. "I couldn't very well open the library door. If the door between the library and the smoking-room was open, I should have been certain to hear something that was not meant for my ears. And it generally is open in summer time. But I should think it very likely that the lady came in by that window. It's always open in summer time. In fact, his lordship always went out into the garden through it, going from his smoking-room."

"And what time was it that you heard this?" he said.

"A few minutes past eleven. I looked round the drawing-room and the two dining-rooms, and it was a quarter-past eleven when I came into my room."

"That's the first exact time I've got from any one yet," said Mr. Flexen in a tone of satisfaction. "And that's all you heard?"

She hesitated, and a look of distress came over her face. Then she said: "You have questioned Elizabeth Twitcher. Did she tell you anything about his lordship's last quarrel with her ladyship?"

"She did not," said Mr. Flexen. "Mr. Manley told me that she had told him about the quarrel. But I did not question her about it. I left it till later."

Mrs. Carruthers hesitated; then she said: "It's so difficult to see what one's duty is in a case like this."

"Well, one's obvious duty is to make no secret of anything that may throw a light on the crime. Was it anything out of the way in the way of quarrels? Wasn't Lord Loudwater always quarrelling with Lady Loudwater?

I've been told that he was always insulting and bullying her."

"Well, this one was rather out of the common," said Mrs. Carruthers reluctantly. "He accused her of having kissed Colonel Grey in the East wood and declared that he would divorce her."

"It was Colonel Grey, was it?" said Mr. Flexen.

"That is what Elizabeth Twitcher told me after supper last night. It seems that his lordship burst in upon them when she was dressing her ladyship's hair for dinner and blurted it out before her. I've no doubt she was telling the truth. Twitcher is a truthful girl."

"Moderately truthful," said Mr. Flexen in a somewhat ironical tone.

"Of course she may have exaggerated. Servants do," said Mrs. Carruthers.

"And how did Lady Loudwater take it?" said Mr. Flexen.

"Twitcher said that she denied everything, and did not appear at all upset about it. Of course, she was used to Lord Loudwater's making scenes. He had a most dreadful temper."

"M'm," said Mr. Flexen, and he played a tune on the table with his finger-tips, frowning thoughtfully. "Was Colonel Grey--I suppose it is Colonel Antony Grey--the V.C. who has been staying down here?"

"Yes," said Mrs. Carruthers. "He's at the 'Cart and Horses' at Bellingham."

"Was he on good terms with Lord Loudwater?"

"They were quite friendly up to about a fortnight ago. The Colonel used to play billiards with his lordship and stay on to dinner two or three times a week. Then they had a quarrel--about the way his lordship treated her ladyship. Holloway, the footman, heard it, and the Colonel told his lordship that he was a cad and a blackguard, and he hasn't been here since."

"But he met Lady Loudwater in the wood?"

"So his lordship declared," said Mrs. Carruthers in a non-committal tone.

"Do you know how Lord Loudwater came to hear of their meeting?"

"Twitcher said that he must have had it from one of the under-gamekeepers, a young fellow called William Roper. Roper asked to see his lordship that evening and was very mysterious about his errand, so that it looks as if she might be right. None of the servants ever went near his lordship, if they could help it. It had to be something very important to induce William Roper to go to him of his own accord."

"I see," said Mr. Flexen thoughtfully. "Well, I'm glad you told me about this. Do you suppose that this Twitcher girl has talked to any one but you about it?"
