If you are going to make companies, corporations, actually responsible for the safety of other people's lives, then if they fail in their duty, the only thing to prevent them failing in their duty is the fear that they would be put behind bars.

A writer's work may be a coded autobiography, but only a very close friend could decipher it.

I was born in a small suburb of Ilford in a rather nasty housing estate that my mother despised. She had grown up in the country, so when the war came and I was evacuated to Wales she thought I was much better off there.

I like stirring the pot - I think it's part of my duty, to shake people up a bit - make them look at things in a different way.

I was cleaning out the pigsty at a farm in Wales, where my mother had rented a room, when the results of my final school exam were handed to me by the postman, along with the news that I had a state scholarship to Oxford. I had waited for this letter for so many weeks that I had abandoned hope, deciding that I had failed ignominiously.

I like writing for children. It seems to me that most people underestimate their understanding and the strength of their feelings and in my books for them I try to put this right.

I grew up on a suburban street with lace curtains and dull neighbours, so I made up stories to tell my friend, in which they became serial killers and burglars. She told her mother, who then told mine.
