The dead couple Olof and Carolina Wachman are found murdered in their magnificent estate. The investigation finds that she has been tortured and raped in front of her husband before they were both killed. A death that must have been a relief after the torture they both went through.
Kurt Wallanders daughter Linda and DI Stefan Lindman now have to show that they are as good a pair of investigators as Kurt Wallander himself.
Slowly but surely we see that the murder is about revenge, a revenge that can be traced back 20 years.
Three youngsters are shot dead whilst having a woodland picnic in fancy dress. The corpses are found, and a friend of the victims is also slain, having told Wallander that his workmate was really gay, and that he is a transvestite, and a wholly murderous one, who adds to his toll of dead by killing a further trio of innocents.
