I'm trying to exploit the bestseller, in a way, but not in the sense of repeating the formula. It's just that the bestseller did so well economically that now I'm freer to do what I want to do, or to try out what I want to try out.

I think I can work anywhere, but you don't get the same kind of inspiration everywhere. New York theater has become a big inspiration for me. I only started writing for the stage myself because I like to see the good, mostly off-Broadway plays in New York.

I wanted to write a book that would leave open many riddles and mysteries, even to me. Of course in some cases I do know the answers, but in many others I don't know and don't want to know.

When I write a book I'm always questioning the project as a whole. I always feel I might have to just throw it away and forget about it, and I've done that with novels I've started and worked on for a long time. It's an option I need in order to write freely.

So the fact that there's someone who's planning what happens to the characters, writing it down, means that the characters always have a fate. And when we think about fate, we tend think of it as the thing we would have if we were literary characters, that is, if there were somebody out there, writing us.

English has a better way with colloquialisms. It has colloquialisms that are colorful and expressive but not too heavy or distracting. In German, if you use colloquialisms, it quickly descends into some kind of dialect literature.

You say fate is almost indispensable to literature - I think it's completely indispensable, at least in a novel, because a novel always has a plot. Even if nothing happens, even if someone just spends a day walking around Dublin, or whatever, there's still something going on.
