“Yes, yes,” said Lady Charles drearily. “The servants in both our families always have names like that. One of you boys go and find Giggle, will you?”

Alleyn watched the twin on the left-hand end of the sofa hitch himself up and walk away. “That’s the one that stammers,” thought Alleyn. “He’s got a mole behind his left ear.”

“Thank you, Stephen,” murmured his mother. The other twin stared uneasily at her, met Alleyn’s glance and looked quickly away.

Alleyn asked Lady Charles when Dr. Kantripp was expected to come back. She said that he had told her he had two visits to make and would call in to see Lady Wutherwood on his return. An image of Lady Wutherwood began to take hold of Alleyn’s imagination and, while he waited for Stephen Lamprey to fetch the chauffeur, he made a picture of her. She would be lying on Lady Charles’s bed in the second room on the left in Flat 26, the room next to that other where her husband waited for the police mortuary van. What was she like, this woman whose screams had risen with the returning lift, who had stumbled through the doors into Lady Charles’s arms, who was (he remembered Lord Charles’s profound uneasiness) not English? What lay at the back of her apparently severe prostration? Grief? Shock? Fear? Why did the Lampreys, incredibly garrulous on all other topics, close down on the subject of their aunt? It was not his habit to speculate on the characters of people whom he was about to interview, and he checked himself. Time enough for him to form an idea of Lady Wutherwood when he met her.

The far door opened. Stephen Lamprey came in, followed by a tall man in a dark grey chauffeur’s uniform.

“This is G-Giggle,” said Stephen.

Evidently Giggle was nervous. He stood to attention and kept closing and unclosing his mechanic’s hands. He sweated lightly and was inclined to show the whites of his eyes. He had a large palish face and bleached eyebrows that met in a thicket over his snub nose. He eyed Alleyn with an air half-mulish, half-apprehensive, but gave his answers crisply enough, thinking for a moment, and then speaking without hesitation. Alleyn began by asking him if he knew what had happened to Lord Wutherwood. With an uneasy look at Lord Charles, Giggle said Mr. Baskett had told him his lordship had met with a fatal accident.

“We are afraid,” said Alleyn, “that it was not an accident.”

“No, sir?”

“No. It looks very much as though there has been foul play. You will understand that the police want to know the whereabouts of everyone in the flat from the time Lord Wutherwood was last seen, uninjured and apparently unthreatened, until the moment when the injury was discovered.”

He stopped and Giggle said doubtfully: “Yes, sir.”

“All right. Now, did you hear his lordship call out after he went out on the lift landing?”
