“And afterwards?”

“Straight back here, where I was when Miss Tony came in.”

“What time did you get back?”

“Twenty minutes past eleven. You can ask Mr Peters, if you like - you'll find him farther down the mews. He owns the lock-up garages, and he saw me come in, and asked me what the picture was like. Which I told him.”

There was nothing more to be got out of her. Hannasyde let her go, and in a few minutes had left the flat himself.

For some moments after the front door had shut behind the Superintendent no one spoke. It was Murgatroyd, coming back into the room, who broke the silence. “I've got my vegetables to do,” she said prosaically, “let alone all this washing up, so it stands to reason I can't waste time talking. You'd better come and give me a hand, Miss Tony. You won't do any good sitting there looking scared. It's a nasty set-out, and no mistake, but brooding won't mend matters.”

Antonia looked at Giles. “Giles, it's all getting so beastly,” she said. “I didn't mind about Arnold, but I hate this! Kenneth - you were at the Albert Hall the whole night, weren't you?”

“God bless the girl, now she thinks I did it!” Giles said, watching Kenneth: “You lied badly. You were in Roger's flat last night, weren't you?”

“He wasn't! I tell you he never left the Hall!” Leslie struck in fiercely.

Giles paid no heed to her, but kept his eyes on Kenneth's face. Kenneth met that look challengingly.
