Flashbacks reveal how Oleg, Gusto, and Gusto's foster-sister Irene got involved in the violin trade, and how Irene has been kidnapped by the man who developed violin to use as a sex slave.

This theory is seemingly confirmed when Oleg is attacked in his cell moments after Hole leaves. Hole becomes convinced that the police have the wrong suspect and that Oleg has been arrested to take the heat off the real violin dealers. Pretending to be Oleg's lawyer, Hole manages to sneak into his cell to get his side of the story.

He discovers that drug-pushers who deal in violin wear Arsenal football shirts and, using this clue, manages to obtain a sample. Hole discovers that the drug scene in Oslo no longer revolves around heroin, but around a highly-addictive morphine-based drug called violin. Hole meets an elderly priest who, throughout the novel, gives Harry seemingly random information that ultimately aids him in solving Gusto's murder. Meanwhile, an airline pilot is arrested for smuggling heroin, but-thanks to a mole within the Oslo police, he is released and is pressured into working more intimately for the drug dealing gang. Since Hole has become a father figure to Oleg, he comes to Norway to determine the truth about the murder. Inspector Harry Hole is returned from his self-imposed exile in Hong Kong when he is told that Oleg, the son of his on-off girlfriend Rakel Fauke, has been arrested for the murder of his flatmate, Gusto.
