Here's what Nesbø had to say about that fun topic in my interview with him:
There's a big wave of Nordic crime fiction. Do you consider yourself part of that?© Peter Rozovsky 2011
I am part of that whether I consider myself part of it or not because it's sort of a commercial label. It doesn't necessarily have much to do with Scandinavian writers having the same style. When I've been asked what I think are the similarities between Scandinavian authors, I would say that they were either from Denmark, Norway or Sweden.
I think my style is probably closer to some of the American writers — Bukowski, Hemingway — than to other Scandinavian writers. Then again, I write from Oslo, so the atmosphere would probably be similar to Stieg Larsson or Henning Mankell.
For me, my inspiration doesn't come mainly from Scandinavian crime writers. It comes from Scandinavian literature, like Knut Hamsun, Henrik Ibsen, lots of other Norwegian and Danish and Swedish writers.
