Lawyer Sten Torstenssen tells Wallander he believes his old father's death in a car crash was homicide but Wallander is reluctant to act until Sten is found hanged and the pathologist claims that he was murdered. Sten's secretary shows Wallander a postcard of Africa with a text threatening the lives of father and son and wealthy philanthropist Harderberg, a client of Sten's, admits to also having received one. All were posted from the same hotel, apparently by industrialist Jurgen Nordfeldt, who survives an attempt to kill him. Nordfeldt had stumbled on a racket importing body parts from Africa which Wallander, helped by ex-cop Anders, now Harderberg's security guard, must resolve.
