The Sandhamn Murders

On a trip with her two children to the beach, Nora Linde discovers a body in the water; Inspector Thomas Andreasson is assigned the case and dismisses the initial assumption of drowning, suspecting murder.

Nora helps a friend on the police force investigate, which leads to a suspect and a jealous husband.

Nora's children go missing, and she turns to her friend Signe for support.
