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'm often asked how I write books, but I don't think my approach is suitable for everyone. If I walked into a creative writing class, all I could say to them was 'I tend to make it up as I go along.' I'm not sure that's brilliant advice.

I don't think I have one particular favourite writer. I have many whose works I will always buy or reread - Muriel Spark, Anthony Powell, Robert Louis Stevenson, Ruth Rendell, James Ellroy, William McIlvanney, Kate Atkinson, John Burnside, Louise Welsh, Iain Banks.
