Some after-the-fact storytelling is inevitable, and, in fact, very good and useful. But then we want always to be able to enrich the stories, or maybe change the stories with a fresh infusion of specificity.

There's a time and place for the Kindle, and I own one now and have books on it that I don't otherwise have. But I don't find that my hand reaches out for it the way it does for a trade paperback, or (in the middle of the night) for the iPod Touch.

Writing has to do with truth-telling. When you're writing, let's say, an essay for a magazine, you try to tell the truth at every moment. You do your best to quote people accurately and get everything right. Writing a novel is a break from that: freedom. When you're writing a novel, you are in charge; you can beef things up.

In my case, adulthood itself was not an advance, although it was a useful waymark.

Wikipedia is just an incredible thing. It is fact-encirclingly huge, and it is idiosyncratic, careful, messy, funny, shocking and full of simmering controversies - and it is free, and it is fast.

I'm a sucker for interiors and carefully, beautifully filmed people sitting in a big room. My appetites are simple.

I wrote about World War II because I didn't understand it. I think that's the reason that historians are drawn to any subject - there's something about it that doesn't make sense. I wanted to work my way through what happened slowly, and look at everything in the order in which it took place.
