Harry talks to Filip Becker, who is in prison. Filip tells him that he only talked to Camilla, who was alive when he left. When Harry asks what he talked to Camilla about and why he called Idar, Filip refuses to answer. Harry knows that Filip is holding out on him, and Filip finally admits that he found Birte’s little black book and had cracked her code.

Erik Lossius, Camilla’s husband, is smart, ruthless, and very successful. He makes a habit of sleeping with the female customers of his moving company, including Birte Becker. Now, 10 years later, Harry asks Erik if he knew Birte Becker. Filip gave Harry Birte’s book, containing a list of names, phone numbers, and dates of men she had seen. Eric was the most frequently listed, which was why Filip came to his house with Jonas’s imitation gun. When he found Camilla instead of Erik, Filip told her the entire story.

Later, Harry tells the story to Rakel while they are in bed. He also mentions the radio report he heard that 15-20% of children in Scandinavia have a different father than they think. However, Erik had an alibi for the night Birte disappeared. Rakel asks what he thinks of her for having an affair with him.
