Chief Inspector Erik Winter of the Gothenburg police force faces a puzzling missing person case: A brother and sister report that their father has disappeared, and they believe he may have gone to Scotland in search of "his" father, who was presumed to have died in World War II. With the help of an old friend from Scotland Yard, Winter sets off to the land of malt whiskeys in search of the truth.
Meanwhile Winter's colleague Aneta Djanali, Gothenburg's African-Swedish female detective, takes a report about a suspected abused wife. But she cannot find the woman, who seems to have disappeared except for mysterious phone messages she sometimes leaves, and her family won't say where the missing woman is. The case becomes personal for Aneta as she receives chilling threats from someone who clearly doesn't want her to find the missing woman.
This mystery featuring Chief Inspector Winter is an outstanding psychological thriller, a character study of great depth and skill by a Swedish master.
