Because I write prose, when I sat down to write a comic, it feels like my brain's working differently. It actually feels like different bits of my head are springing into action.
I'm always represented as a bit of a class warrior - a bit Down With Men and Down With Middle-Class People. Whereas I'm actually very fond of men and am middle-class. I even went to boarding school in Perthshire.
If you went for a job interview in a Glasgow law firm, they used to ask you what school you went to. And that was a way of finding out what religion you were.
People are very frightened in publishing at the moment. Nobody knows what sells. More so now because the market's changing so fundamentally because of Kindle and electronic publishing. It's a fundamental shift in the way stories are put out into the world.
The book I made it big with in the U.S. was my fourth book, 'Sanctum.' My novels sell really well both there and in Canada, so once a year I do a promotional tour, visiting a different city every two days, doing book readings and signings.
There's always these giant baffling books, like 'The Da Vinci Code.' People say it's not as well written as 'Midnight's Children.' Why aren't people reading 'Midnight's Children?' Nobody knows why these phenomenons happen but they're great.
I think the class divide is going to change. I think a lot more working class people are going to get published. It is really class ridden, literature.
My upbringing was middle-class but my parents' families were both working-class so I had this odd combination of working-class background but in a privileged position.
My family were great story-tellers. My mum was one of 12 and they were all fighting to tell stories. You have to tell a good tale or no one is going to listen. You have to make it entertaining and interesting. That's how I learned to tell stories.
In the 'Garnethill' trilogy, people always forget that Maureen O'Donnell's dad was a journalist and she did art history at uni and her brother did law, but no-one ever thinks they're middle-class - they're just working class because they speak with accents.
I'm not much of a plotter. I start off with an inciting incident, and in classic crime fiction what happens is that all the action flows from that incident. It's very comfy when it all ties up and feels like a complete universe, but my stuff doesn't always work that way.
I respond very well to rules. If there are certain parameters it's much easier to do something really good. Especially when readers know what those are. They know what to expect and then you have to wrong-foot them. That is the trick of crime fiction. And readers come to crime and graphic novels wanting to be entertained, or disgusted.
