I invented the historical spy novel.

I wrote three mysteries and then a contemporary spy novel that was unbelievably derivative - completely based on 'The Conversation,' the movie with Gene Hackman. Amazingly, the character in the book looks exactly like... Gene Hackman.

Graham Greene's work must be included in any survey of top-rank spy novels, and 'Our Man in Havana' may be his best.

Le Carre's voice - patrician, cold, brilliant and amused - was perfect for the wilderness-of-mirrors undertow of the Cold War, and George Smiley is the all-time harassed bureaucrat of spy fiction.

If I'm a genre writer, I'm at the edge. In the end, they do work like genre fiction. You have a hero, there's a love interest, there's always a chase, there's fighting of some kind. You don't have to do that in a novel. But you do in a genre novel.

I don't regard it as a historical novel, I regard it as a novel of now, which just happens to be set when it is set,
