When a murder attempt is made on Robert's brother Jon, it is believed that the Karlsen family is being attacked.

Hole, Halvorsen, and Lønn are assigned to Robert Karlsen's murder. Møller is replaced as senior police inspector by Gunnar Hagen. Hole's is a wristwatch which grows to annoy him due to its incessant ticking. Meanwhile, retiring Oslo police inspector Bjarne Møller gives his three main officers – Jack Halvorsen, Beate Lønn, and Harry Hole – gifts. As such, despite the murder happening in a public place, the Norwegian police get little useful information regarding the killer. Stankić has a facial anomaly known as hyperelasticity, wherein his facial muscles can be manipulated voluntarily to stop people from recognizing him. In the present day (2003), the assassin – calling himself Stankić – arrives in Oslo and kills a Salvation Army officer, Robert Karlsen, during a Christmas street concert. The fighter, who receives the nickname "Little Redeemer", later becomes a professional assassin who carries out contract killings in various European cities. That same year, during the breakup of Yugoslavia, a young Vukovar Croat fighter witnesses atrocities committed by the victorious Serb militias in the aftermath of the Battle of Vukovar. Because of the Salvation Army's strict hierarchical setup, and because revelation of the rape will severely damage the organisation's reputation, she does not tell anyone about the ordeal. In 1991, at a youth camp run by the Norwegian Salvation Army, the 14-year-old daughter of a senior Salvationist official is raped in a public toilet. It is the sixth entry in his Harry Hole series. The Redeemer ( Norwegian: Frelseren) is a novel by Norwegian crime-writer Jo Nesbø.
