"Your maid?" Robert suggested. "Servants have ways of marking their domestic life that is often surprising."

"We have no maid," she said. "We find it difficult to keep one: The Franchise is so isolated."

The moment threatened to become awkward and Robert hastened to break it.

"This girl-I don't know her name, by the way."

"Elisabeth Kane; known as Betty Kane."

"Oh, yes; you did tell me. I'm sorry. This girl-may we know something about her? I take it that the police have investigated her before accepting so much of her story. Why guardians and not parents, for instance?"

"She is a war orphan. She was evacuated to the Aylesbury district as a small child. She was an only child, and was billeted with the Wynns, who had a boy four years older. About twelve months later both parents were killed, in the same 'incident, and the Wynns, who had always wanted a daughter and were very fond of the child, were glad to keep her. She looks on them as her parents, since she can hardly remember the real ones."

"I see. And her record?"

"Excellent. A very quiet girl, by every account. Good at her school work but not brilliant. Has never been in any kind of trouble, in school or out of it. 'Transparently truthful' was the phrase her form mistress used about her."

"When she eventually turned up at her home, after her absence, was there any evidence of the beatings she said she had been given?"
