In July 1946 two schoolboys found the body of a woman on a bombsite in north London. It's a while before she's identified as Lillian Frobisher, but that produces more problems. Lillian was - apparently - a respectably married woman but the encounter on the bomb site had been sexual and almost certainly consensual. And why was her husband not aware that his wife was missing? His position looks even worse when it emerges that the body was lying on an expensive mackintosh sold in the store where he's a doorman. But was Lillian quite as respectable as she would have had everyone think?
