"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."
