The married couple Olof and Carolina Wrangel are found murdered on their magnificent estate. The investigation shows that the woman was tortured and raped in front of her husband’s eyes before they both met death. A death that must have come as a liberation in the face of the covert torture they both had to endure. To help with the case, Kurt Wallander has his daughter Linda and forensic investigator Stefan Lindman, both of whom now show that they are at least as good investigators as Wallander.
Slowly but surely, everything points to the fact that the staged double murder is about revenge, a revenge that dates back 20 years in time.
