Many Scandinavian writers who had made their name in literary fiction felt they wanted to have a go at the crime novel to show they could compete with the best. If Salman Rushdie had been Norwegian, he would definitely have written at least one thriller.

My influence is probably more from American crime writers than any Europeans. And I hardly read any Scandinavian crime before I started writing myself. I wasn't a great crime reader to begin with.

For many years, it seemed as if nothing changed in Norway. You could leave the country for three months, travel the world, through coups d'etat, assassinations, famines, massacres and tsunamis, and come home to find that the only new thing in the newspapers was the crossword puzzle.

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.

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.

Harry looked at Bellman. He could not help but admire him. The way you admire a cockroach you flush down the toilet and it comes creeping back again and again and in the end it inherits the world.

For me, the best places to write are on planes, trains and at airports. Not hotel rooms but hotel lobbies. I'm really happy when I'm waiting for a plane and the message comes that it's three hours late. Great, I'll get to write!
