Plan for Chaos - John Wyndham

In a city that could well be New York, a series of identical women are found dead in suspicious circumstances. Magazine photographer Johnny Farthing, who is reporting on the suspected murders, is chilled to discover that his fiancée looks identical to the victims too - and then she disappears. As his investigations spiral beyond his control, he finds himself at the heart of a sinister plot that uses cloning to revive the Nazi vision of a world-powerful master race...Part detective noir, part dystopic thriller, Plan for Chaos reveals the legendary science fiction novelist grappling with some of his most urgent and personal themes.
