After a few minutes there was a tap on the far door, which the constable opened. Fox’s voice was heard in a brief mumble and in a moment he came in.

“Mr. Alleyn, my lord,” said Fox, “would be obliged if Lady Patricia could come to the dining-room for a few minutes.”

“Off you go, Patch,” said her mother. Her voice had lost nothing of its crispness, but, as Patch passed her, she took her hand and gave her a smile that to Roberta seemed like a brief flash of desperate anxiety. Patch went out.

“It’s rather like French Revolutionary films,” said Frid. “You know, the ones where the little group of aristocrats gets thinner and thinner.”

“Manners, love,” said Frid in Cockney.

“Well,” he said, “she’ll do all right, Lady Charles. She’s better. Had a sleep and less agitated. Still rather upset of course. Inclined to be…” He made an expressive gesture.

“Mad?” asked Frid. “Stark ravers, would you say?”

“My dear girl, not that of course, but rather unsettled and unlike her usual self, no doubt.”
