Bruno Courreges is chief of police of the lovely Dordogne town of St Denis with a remit that covers the beautiful valley of the river Vezere. One autumn morning he comes across an abandoned car parked near a local beauty spot. Inside is a dead woman, Monique, an apparent suicide resulting from depression. But there are circumstances surrounding the death that raise Bruno's suspicions, particularly when disputes arise surrounding her Will.
At the same time, Bruno makes the mistake of interfering in a local marital dispute. Deputy mayor Xavier has been playing away and finds himself evicted from the family home. Old controversies about deer culls take on new life and then a second campaign begins, stating that Bruno is less of a village copper and more of a secret policeman, whose main job is working for French intelligence. Some of the ammunition for this attack, Bruno learns, comes from Xavier, who sees this as a way to topple Bruno and the mayor and succeed to the mayor's job himself.
Suddenly Bruno's shiny reputation is looking a little tarnished as he battles to save his name and answer the questions surrounding Monique's suicide.
