I grew up reading genre writers, and to the degree that Eric Ambler and Graham Greene are genre writers, I'm a genre writer.

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'm not really a mass market writer.

When I get asked about novelists I like, they tend to be white, male, and British, like Graham Greene. They write the kind of declarative sentences I like. I don't like to be deflected by acrobatics.

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

I don't inflict horrors on readers. In my research, I've uncovered truly terrible documentations of cruelty and torture, but I leave that offstage. I always pull back and let the reader imagine the details. We all know to one degree or another the horrors of war.
