And when I was young, did I ever tell you, I always wanted to get inside a book and never come out again? I loved reading so much I wanted to be a part of it, and there were some books I could have stayed in for ever.

There are two types of people, you see. One type keep their heads straight, and look around as they walk. The others look up - at the tops of houses, at the eaves and the lintels and the roofs, which can tell you when they were built - and I've always done that.

None of my books has been ever in my head; after they're finished, they go. It's like being a sort of medium; you just grab it when it's there then just release it when it's time to go. There's a lot of instinct, not planning.

The endless chatter of this journey had wearied me.

I wanted to be a poet when I was 20; I had no interest in fiction or biography and precious little interest in history, but those three elements in my life have become the most important.

London has always provided the landscape for my imagination. It becomes a character - a living being - within each of my books.

Rioting has always been a London tradition. It has been since the early Middle Ages. There's hardly a spate of years that goes by without violent rioting of one kind or another. They happen so frequently that they are almost part of London's texture.
