All over Oslo, celebrities are turning up dead in the most macabre of situations: a talk show host with her tongue cut out, a politician crucified with a copy of the Koran stuffed up her private parts, a literary critic stabbed in the eye. It's clear that the killer seeks some sort of retribution, but for what?

Adam Stubo and Johanna Vik, recently new parents, are reluctantly drawn into the investigation. As Stubo leads the inquiry, Johanna is exhausted by the new baby. But she is haunted by a pattern she discovers from a time long ago when she was in the FBI, a time she has tried to forget . . . and time is running out to stop the killer from completing this chilling series of murders.
