When a dead man is lifted from the freezing waters of Oslo Harbour just before Christmas, Detective Lena Stigersand's stressful life suddenly becomes even more complicated. Not only is she dealing with a cancer scare, a stalker and an untrustworthy boyfriend, but it seems both a politician and Norway's security services might be involved in the murder. With her trusted colleagues, Gunnarstranda and Frølich, at her side, Lena digs deep into the case and finds that it not only goes to the heart of the Norwegian establishment, but it might be rather to close to her personal life for comfort.
