"I don't think I can. I hardly know her. She's an old friend of Arthur's, and she came to live here about a year after he did. I've always imagined that she could tell some pretty ripe tales about him if she wanted to because he was much more polite to her than to anyone else."

"Do you know why it was she who went to fetch the General on to the terrace?"

"Yes, of course I do. She came specially to talk to him about Geoffrey, because she was about the only person he'd listen to. That's what makes me think he was a bit afraid of her."

"Is there a Mr. Twining?"

"Colonel. He's dead."

"I see. Tell me what happened when she went to the General's study. How long was she gone?"

Dinah pondered this. "I'm not sure. We were all talking. I should think, about five minutes, or even a little longer."

"And when she came back-was she very much upset:'

"Yes, I think she was. In fact, I'm certain she was. She's awfully self-controlled, and doesn't give away much but she looked pretty queer. I'm not surprised: she actually touched Arthur before she realised he was dead, and her glove was all over blood. Luckily she's strong-minded enough not to have fainted on the spot."

Harding nodded rather absently. He did not say anything for a minute or two, and Miss Fawcett. respecting this mood of abstraction, sat and studied him in silence. Aware presently of her clear gaze, he glanced down at her, and smiled. "Has Billington-Smith broken off his engagement to Miss de Silva?" he asked.
