Stories about mental aberration and oddity only make sense in context. Just how do people live with someone who is peculiar, gifted, strange or alien? It's odd because there's a little part of me that wants to write about exotic, strange bizarre subjects. Instead, I've rather reluctantly realised that what I write about is families.

Indeed, I am repeatedly astonished by the number of really good writers who understand human beings so well on paper but don't know how to deal with them in real life.

If one book's done this well, you want to write another one that does just as well. There's that horror of the second novel that doesn't match up.

And when the universe has finished exploding all the stars will slow down, like a ball that has been thrown into the air, and they will come to a halt and they will all begin to fall towards the centre of the universe again. And then there will be nothing to stop us seeing all the stars in the world because they will all be moving towards us, gradually faster and faster, and we will know that the world is going to end soon because when we look up into the sky at night there will be no darkness, just the blazing light of billions and billions of stars, all falling.

Usually people look at you when they're talking to you. I know that they're working out what I'm thinking, but I can't tell what they're thinking. It is like being in a room with a one-way mirror in a spy film.

When I was 13 or 14, I started devouring novels; literature took quite a while to take me over, but it caught up just in time to save me from becoming a mathematician.

There was a time in my life when I was going in and out of houses that were extraordinarily different - from a working-class terrace in Northampton to the homes of friends who were really very wealthy. It was quite an odd position to be in, I realise looking back, and quite a nice one.
