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.

I hate it when I'm reading a comic, and the dialogue looks like stickers stuck on top to explain what's going on. For me the best is when your eye goes in a certain point and moves through the composition and then springs out on the dialogue, or gets confused in the image and then goes to the dialogue for an explanation.

I grew up in London under Thatcher and that really was disgusting. A feeding frenzy.

People are interested in crime fiction when they're quite distanced from crime. People in Darfur are not reading murder mysteries.

Even if people do wrong, we're social animals, so what can we do about stopping them doing the same things in future? Saying people are 'bad' or 'evil' is just an unwillingness to engage; an unwillingness to try to empathise. That sanctimonious attitude doesn't help anyone

We don't really go in for big family dinners, but Scottish people are famously confrontational. It's a cultural thing, so maybe we don't need to have them to clear the air. Also, traditional family food isn't as nice here so there's no payoff for traveling hundreds of miles.

Most of the people who write to me are really clever, really engaged. They just want to say that they have read my book and liked it.
