Career The Harry Hole series The series follows Harry Hole, a tough detective working for Crime Squad and later with the National Criminal Investigation Service (Kripos), whose investigations may take him from Oslo to Australia, Thailand, West Congo, Switzerland or Brazil. Hole takes on seemingly unconnected cases, sometimes found to involve serial killers, bank robbers, gangsters or the establishment, but spends a significant amount of time battling alcoholism and his own demons. The Harry Hole novels are multi-layered, violent and often feature women in peril, as typified by The Snowman. On the return of Harry Hole in The Thirst, Nesbø said: "I was always coming back to Harry; he is my soul mate. But it is a dark soul, so it is – as always – both a thrill and a chilling, emotionally exhausting experience. But Harry and the story make it worth the sleepless nights." A film adaptation of The Snowman, with Tomas Alfredson directing (replacing Martin Scorsese, who executive produced), and starring Michael Fassbender, Rebecca Ferguson, and Charlotte Gainsbourg, premiered in October 2017. The Doctor Proctor series Doctor Proctor's Fart Powder, originally published in 2007, was Nesbø's first children's book. They are illustrated by Mike Lowery. The series is set in Oslo, Norway and follows the story of Doctor Proctor, a crazy professor waiting for his big break, his next-door neighbor Lisa and her peculiar friend Nilly, a short redheaded boy.
