Silvia, ever so slightly, withdrew herself.

“Did I?” she asked.

“Of course you did. Now do be fair. You began, and therefore it’s your turn to bring out the first piece of evidence. It was in Richmond Park, you know, and she told you something about yourself which you didn’t know.”

Peter put his hand in some judicial manner through that short crisp hair above his neck.

“I am prepared to hear your evidence,” he said. “You’re on oath. Get on, Miss Silvia. Don’t keep the court waiting.”

Silvia shot a chance arrow.

“If I promise to tell you,” she said, “will you promise to tell me your evidence?”

Peter laughed.

“I think we’re both better at cross-examination than at confession,” he remarked.

“Oh, but that’s no answer,” she said.
