St. Denis chief of police Bruno Courreges helps his mentor solve a case that’s puzzled him for decades.
Chief Detective Jalipeau, known to his closest friends as J-J, keeps a skull on his desk in the South of France. Not as a memento mori but as a reminder that as far as he’s risen, there’s still one case—his first—that he’s been unable to solve. Then Bruno gets a brain wave. While looking at displays of Neanderthals in the local museum, he wonders: Why can’t whoever restored these primitive folk help J-J reconstruct Oscar, as he calls his bony souvenir? Bruno tracks down anthropologist Elisabeth Daynès, who recommends Virginie, a graduate student who’s ready for a new challenge. While Virginie is hard at work re-creating Oscar’s musculature, Bruno has a second idea. Why not trace Oscar’s DNA through modern data banks? He quickly gets a hit and just as quickly hits a wall. Oscar had a son, a soldier named Louis Castignac, who was recently killed in action in Mali. As Castignac’s half sister, Sabine, who happens to be a gendarme, helps Bruno try to figure out who her brother's biological father was, Bruno deals with a host of other entanglements. His cousin Alain is getting married. His basset hound, Balzac, has just sired a litter, and he wants to choose two perfect homes for the puppies he will receive as a stud fee. His journalist friends Gilles and Jacqueline have caused a stir by publishing articles about the Rosenholz dossier, a secret document containing names of French agents who worked for the Stasi. Perhaps most urgent, drought has threatened St. Denis with wildfires, and Bruno must band together with the other villagers to protect their farms and their homes.
An overdose of subplots blunts the impact of the main event.
