Title: The Upside-Down Man - Fred Vargas - book
Summary :
Letting wolves roam free in the Mercantour was a great idea, in keeping with the times. But it wasn't the idea of the shepherds, and a few months later, revolt rages. But is it really a wolf that's killing the sheep around the village of Saint-Victor? Superstitions resurface, a rumor spreads: it's not a beast, it's a werewolf... When a breeder is found with her throat cut in her sheepfold, the rumor turns to psychosis. In Paris, Commissioner Adamsberg is on the lookout for news of the Beast of Mercantour: Like embers, my boy, like embers, the wolf's eyes make at night.
