In the electrifying first installment of the New York Times bestselling series, Harry Hole of the Oslo Crime Squad is dispatched to Sydney to observe a murder case. As he circles closer to the killer, Harry begins to fear that no one is safe, least of all those investigating the murder.

Shots ring out at a Salvation Army Christmas concert in Oslo, leaving one of the singers dead in the street. The trail will lead Harry Hole, Oslo’s best investigator and worst civil servant, deep into the darkest corners of the city and, eventually, to Croatia.

When Harry left Oslo again for Hong Kong - fleeing the traumas of life as a cop - he thought he was there for good. But then the unthinkable happened. The son of the woman he loved, lost, and still loves is arrested for murder: Oleg, the boy Harry helped raise but couldn't help deserting when he fled. Harry has come back to prove that Oleg is not a killer. Barred from rejoining the police force, he sets out on a solitary, increasingly dangerous investigation that takes him deep into the world of the most virulent drug to ever hit the streets.

For years, detective Harry Hole has been at the center of every major criminal investigation in Oslo. His brilliant insights and dedication to his job have saved countless lives over the years. But as the killer grows increasingly bold and the media reaction increasingly hysterical, the detective is nowhere to be found. This time, when those he loves and values most are facing terrible danger, Harry is in no position to protect anyone—least of all himself.

Oslo in November. The first snow of the season has fallen. A boy named Jonas wakes in the night to find his mother gone. Out his window, in the cold moonlight, he sees the snowman that inexplicably appeared in the yard earlier in the day. Around its neck is his mother’s pink scarf. Hole suspects a link between a menacing letter he’s received and the disappearance of Jonas’s mother - and of perhaps a dozen other women, all of whom went missing on the day of a first snowfall. As his investigation deepens, something else emerges: he is becoming a pawn....
