"You can change your mind, of course."

"I shan't, honestly, until you turn stupid. And you can't do that until

"I knew you must be David Amber the moment I heard you speaking Urdu."

"And the man at the station wasn't mistaken--unless I am. He knew me
perfectly, I believe, but for reasons of his own refused to recognise

"You have?"
