I don't think that you can be prescriptive about anything, I mean, life is too complicated. Maybe there are novels where the author has not in the least thought about it in terms of film, which can be turned into good films.

I was always very curious as a young man about why older writers who I met seemed so indifferent to what was going on, whereas I, in my 20s, was reading everything. Everything seemed important. But they were only interested in the writers they admired when they were young, and I didn't understand it then, but now, now I understand it.

I've dealt with numbers all my life, of course, and after a while you begin to feel that each number has a personality of its own. A twelve is very different from a thirteen, for example. Twelve is upright, conscientious, intelligent, whereas thirteen is a loner, a shady character who won't think twice about breaking the law to get what he wants. Eleven is tough, an outdoorsman who likes tramping through woods and scaling mountains; ten is rather simpleminded, a bland figure who always does what he's told; nine is deep and mystical, a Buddha of contemplation.

Writing is a solitary business. It takes over your life. In some sense, a writer has no life of his own. Even when he’s there, he’s not really there.

The tone of every book is slightly different; there's a music that each has that is distinct from all the others.

I am very scared at the beginning of each book, because I've never written it before. I feel I have to teach myself how to do it.

What if I had been born during a war and I lived in an occupied city, and people were being taken out and shot every day? Everything would be different - even after the war ended, my future would be very different. Look at what these poor people in Aleppo are going through. The children, the ones who survive, are going to be absolutely altered by what they live through, and you and I, luckily, have never had to deal with that.
