No matter how many awards you've won or how many sales you've got, come the next book it's still a blank sheet of paper and you're still panicking like hell that you've got nothing new to say.

War created bizarre allies, while peace itself could be divisive.

I am, of course, a frustrated rock star - I'd much rather be a rock star than a writer. Or own a record shop. Still, it's not a bad life, is it? You just sit at a computer and make stuff up.

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.

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'm interested in Scotland now and then, how it's changed. I want to get the reader to think about that by thinking about something from the past. How has society changed, how has policing changed, have we changed philosophically, psychologically, culturally, spiritually?

A good album should be more than the sum of its parts.
