I was going to say 'my friend Stuart', but I suppose he's not a friend any more. I seem to have lost a number of friends in the last few years. I don't mean that I've fallen out with them, in any dramatic way. We've just decided not to stay in touch. And that's what it's been: a decision, a conscious decision, because it's not difficult to stay in touch with people nowadays, there are so many different ways of doing it. But as you get older, I think that some friendships start to feel increasingly redundant. You just find yourself asking, "What's the point?" And then you stop.

I was mainly in a state of nervousness while I wrote it - nervousness that it was far bigger and more complicated than anything Id attempted before, and that maybe my talent just wasnt up to it and the book would have to be abandoned, or would turn out not to work at all when it was finished.

My only regret is that I signed away the world rights and in America they've been far and away my most successful books, but I never saw a cent from any of it.

I'm one of those unlucky people who had a happy childhood.

You would go mad if you began to speculate about the impact your novel might have while you were still writing it.

I live a perfectly happy and comfortable life in Blair's Britain, but I can't work up much affection for the culture we've created for ourselves: it's too cynical, too knowing, too ironic, too empty of real value and meaning.

I like the idea of a big caesura between the narratives, a space which readers can fill in with their own speculative history.
