Carl Mørck used to be one of Denmark’s best homicide detectives. Then a hail of bullets destroyed the lives of two fellow cops, and Carl - who didn’t draw his weapon - blames himself. So a promotion is the last thing he expects. But Department Q is a department of one, and Carl’s got only a stack of cold cases for company. His colleagues snicker, but Carl may have the last laugh, because one file keeps nagging at him: A liberal politician vanished five years earlier and is presumed dead. But she isn’t dead...yet.

In Police - the last novel featuring Jo Nesbø's hard-bitten, maverick Oslo detective - a killer wreaking revenge on the police had Harry Hole fighting for the safety of the people closest to him. Now, in The Thirst, the story continues as Harry is inextricably drawn back into the Oslo police force. A serial murderer has begun targeting Tinder daters - a murderer whose MO reignites Harry's hunt for a nemesis of his past.

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.

The story opens with the apparently accidental drowning of a sixth form student in the Norfolk countryside. As a matter of routine, or so it seems, the case passes across the desk of Detective Sergeant Smith, recently returned to work after an internal investigation into another case that has led to tensions between officers at Kings Lake police headquarters. As an ex-DCI, Smith could have retired by now, and it is clear that some of his superiors wish that he would do so.
