I wrote 'Knots and Crosses,' the first of the Rebus books, not even realising that I was writing crime fiction.
I dunno whether it was to do with my parents - we were working-class - but it was important to me to be self-sufficient.
When I'm writing, I won't know whodunnit until maybe two thirds of the way through. Until then, I know as little as my detective. I just make it up as I go along. It's nerve-wracking, actually. You'll be half through and not know your conclusion. You worry one of these days the ending won't come. I'll be left with only two-thirds of a novel.
At all times, think like a writer, and keep those antennae twitching - that way, you pick up new ideas.
I've always written. At the age of six or seven, I would get sheets of A4 paper and fold them in half, cut the edges to make a little eight-page booklet, break it up into squares and put in little stick men with little speech bubbles, and I'd have a spy story, a space story and a football story.
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.
