Dos muertes en Belle-Île

While Brittany is experiencing one of the hottest August months in its history, a corpse appears attached to a buoy near Concarneau. This is Patric Provost, a wealthy and despotic businessman from Belle-Île, owner of land, real estate and even a sheep farm. Dupin and his assistants find out that all but one of the houses in Islonk, a tiny village in the southwest of the island, belonged to the dead man. They soon discover that Provost's ex-wife, from whom he had been separated for twenty years although they were not divorced, and the mayor, embarked on an ambitious green energy project that would provide energy independence to the place, are the main beneficiaries of the inheritance. Just then a kidnapping takes place and another corpse turns up.
