Engström learns from one of Tanja's friends that she had been seeing Jon Holt (Bjørn Floberg), a crime novelist. He correctly deduces that Holt killed Tanja, but Holt blackmails Engström with his knowledge of the Vik shooting. The two meet and decide to frame Tanja's boyfriend Eilert for her murder, with Engström later planting Holt's gun under Eilert's bed. However, Hagen is not convinced of Eilert's involvement, and when new evidence emerges, Engström knows that it's only a matter of time until Holt is arrested.
