It became a habit of mine never to leave the house without a pencil in my pocket.

Often it's true that films just go right through us. You see the film, you might be entertained, and if it's not a great film, it loses its power very quickly. I think even simply acceptable books stay with us a lot longer.

When I start, I have a feeling for the characters, and maybe the shape of the story. Sometimes I might even have the last sentence in mind. But, no book I've ever written has ever ended the way I thought it would. Characters disappear, others come forward. Once you start writing, everything changes.

Becoming a writer is not a 'career decision' like becoming a doctor or a policeman. You don't choose it so much as get chosen, and once you accept the fact that you're not fit for anything else, you have to be prepared to walk a long, hard road for the rest of your days.

Most of the boys would come with bits of equipment that their fathers had given them from their war days - helmets, canteens, binoculars, these kinds of things - that leant a kind of authenticity to the games we were playing. But, of course, my father never gave me anything. So I began to question him. You know, Why don't you have anything from the war? And I think he was...embarrassed to tell me he hadn't fought, because, you know, little boys want to turn their fathers into heroes, and he didn't want to be diminished in my eyes.

There's a difference between doing memoir and writing a novel. If I had put the story of the boy killing my dog - and that was Eric also, what a little monster he was! - in a novel, even if I took it directly from life, it would be fiction.

It was a wrong number that started it, the telephone ringing three times in the dead of night, and the voice on the other end asking for someone he was not.
