Bäckström

Homicide investigator Evert Bäckström is convinced that a crime has been committed when a woman's skull is found on an island in the archipelago. But his investigation is opposed by the chief of police; and when the woman's identity is clarified, the whole investigation is turned upside down.

Bäckström is the first to arrive after celebrity lawyer Tomas Eriksson is murdered. The police initially cannot rule out that Bäckström himself is involved.

Bäckström travels to Palma, Mallorca, with Niemi to pursue a lead in the murder of his childhood friend Sally, his only unsolved case. Meanwhile, an explosion in central Stockholm may be linked to a drug cartel.
