"I think that most of my books are part of some process of self-education, often about the places I go to. Most of all, they are about the peculiar tension between institutional loyalty and loyalty to oneself; the mystery of patriotism, for a Brit of my age and generation, where it runs, how it should be defined, what it's worth and what a corrupting force it can be when misapplied. All that stuff is just in me and it comes out in the characters. I don't mean to preach, but I know I do, and I'm a very flawed person. It's quite ridiculous."
