Ever since the '70s, Maj Sjowall and Per Wahloo were the godfathers of Scandinavian crime. They broke the crime novel in Scandinavia from the kiosks and into the serious bookstores.

I have to feel that I'm going somewhere all the time. By definition, if you have this urge to go places, then you can't be 100 percent happy where you are. It's not like I enjoy being miserable for weeks on end. But I think it's good to be miserable for about one day every third week - that's ideal for me.

The only pressure I feel is to write good books. And to not replicate the previous book. Whether you have a thousand readers or a million readers it doesn't change the pressure. I never feel tempted to give the reader what I think the reader wants.

All my friends who wanted to write had got nowhere trying to write the great European novel. So I deliberately steered clear of that and set out to write something story-led.

All interesting heroes have an Achilles heel.

I've been watching more American TV because of all the great TV series that have come out in the last five to 10 years. I'm a 'Sopranos' fan, I'm a 'Wire' fan, I'm a 'Mad Men' fan. I'm a 'Deadwood' fan. It makes me optimistic for the future of storytelling on TV that producers are willing to take that kind of jump.
