“Indeed you’re not. You’re giving me a delightful picture. But I suppose we must get down to hard facts. I just want to check your own movements. You were in here from the time Lord Charles had his interview with his brother right up to the discovery of the accident. That right?”

“Yes.” Roberta had sorted this out carefully and gave him a clear account of her talk with Michael and her final move to the landing.

“That’s grand,” said Alleyn. “Crisp and plain. There are two points I want to check very carefully…The times when Lord Wutherwood shouted. You tell me that when he first called you were all in here.”

“Yes. Including Mike. He had just come in. But the others went out a second or two after he called out.”

“And the second time?”

“Mike went away with Giggle. A very short time after that Lord Wutherwood called out the second time.”

“You’re quite certain?”

“Yes, quite. Because it was so quiet in the room when they had gone. I remember that, after he had called again, I heard the sound of the lift. Then I heard some one call out in the street below and the voices next door in the drawing-room. It’s all very clear. I heard the lift again just as I took a cigarette out of that box. After that, I remember I walked about hunting for matches. I’d just lit my cigarette and was leaning out over the window still looking at London when I heard her — Lady Wutherwood. It was awful, that screaming.”

“I want you to go through that again if you will.”

Roberta went through it again and, greatly to her astonishment, again. Alleyn read over his notes to her and she agreed that they were correct and signed them. He was silent for a moment and then returned to the subject of the family.
