“I knew you hadn’t,” she said, “when I discovered that you’d never kissed her.”

Gordon’s mouth was occupied with bacon at the moment, but he stood up and made an unearthly noise of protest.

“No, I don’t ask servants such questions,” said Diana primly, “but a woman has instincts, and there’s always a way of finding these things out. Gordon, you are exonerated,” she added with a generous gesture.

“Your philosophy of life is amazing,” he said, after he had recovered some of his calm. “Whatever made you think I should kiss her?”

“Because she’s pretty,” said Diana. “All men want to kiss pretty girls if they’re normal. Lots of people have wanted to kiss me.”

Gordon raised his eyebrows without looking up. He was not revolted; he was simply resigned.

“You haven’t asked me whether I let them,” she said after waiting.

“I’m not interested,” said Gordon coldly.

“Not a teeny weeny bit?”

Anxiety was in her voice, but he was not deceived. He had learnt by hard experience that when Diana was most wistful, she was usually gurgling with internal laughter. A terrible girl.
