I think my heart is quite selfish. If I followed my heart, I would not be a good person. But I have moral principles. I have to sit down and reflect.

I'm not a big crime reader, but I'm reading Michael Connelly's 'The Reversal.' I'm going back to his novels. I'm also reading Keith Richards' 'Life.' I'm always fascinated by the transition from the innocent late '60s and early '70s and the youth culture becoming an industry.

I'm just an entertainer. In a way crime stories are boring. A crime's been committed and at the end you know it will be solved. So you've got to make the story interesting besides it just being a plot. And that's why character matters, why you've got to make the characters interesting.

A moral person is someone who accepts the consequences of their own morality, not those of others.

Everyone has a need to do penance. It's a basic need, like washing. It's about harmony, an absolutely essential inner balance. It's the balance we call morality.

I tell myself I write because I want to say something true and original about the nature of evil. That is very ambitious - to say something about the human condition that hasn't been written before. Probably I will never succeed but that is what I strive to do.

As I say, we Norwegians love our woolens, and you can buy some beautiful knitwear in Oslo. They might cost you a bit - but they will last.
