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.

Two young women are found murdered in Oslo, both drowned in their own blood. Media coverage quickly reaches fever pitch: Could this be the work of a serial killer? The crime scenes offer no coherent clues, the police investigation is stalled, and the one man who might be able to help doesn't want to be found. Traumatized by his last case, Inspector Harry Hole has lost himself in the squalor of Hong Kong's opium dens. Yet when he is compelled, at last, to return to Norway - his father is dying - Harry's buried instincts begin to take over. Then a female MP is discovered brutally murdered.

When the Norwegian ambassador to Thailand is found dead in a Bangkok brothel, Inspector Harry Hole is dispatched from Oslo to help hush up the case. But once he arrives Harry discovers that this case is about much more than one random murder. There is something else, something more pervasive, scrabbling around behind the scenes. Or, put another way, for every cockroach you see in your hotel room, there are hundreds behind the walls.

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.
