I took the first James Kelman novel, 'The Bus Conductor Hines', home to my dad. I thought, 'My dad will like this; it's written in Scots.' But my dad said: 'I can't read that.' He was reading James Bond and John le Carre. That was part of what attracted me to crime - the idea of getting a wide audience.

I still think most writers are just kids who refuse to grow up. We're still playing imaginary games, with our imaginary friends.

My first novel was turned down by half a dozen publishers. And even after having published five or six books, I wasn't making enough money to live on, and was beginning to think I'd have to give up the dream of being a full-time writer.

The most difficult part of any crime novel is the plotting. It all begins simply enough, but soon you're dealing with a multitude of linked characters, strands, themes and red herrings - and you need to try to control these unruly elements and weave them into a pattern.

I don't have many friends. It's not because I'm a misanthrope. It's because I'm reserved. I'm self-contained. I get all my adventures in my head when I'm writing my books.

At all times, think like a writer, and keep those antennae twitching - that way, you pick up new ideas.

You need a great idea, but then you've got to carry it through. If you get it right, you're going to be a critical success. But not everyone who works hard gets it right, or has the success they deserve: there's an element of luck.
