Fabien Cadiou has been shot - a murder in the tranquil village where everyone knows everyone! Then there is another murder victim. It quickly becomes clear to Dupin that the two dead men knew each other and that the murders must be directly connected. A short time later, a third victim is found. What could be the background to this strange series of murders? Is there a secret that the village is hiding? Inspector Dupin begins his investigation.
