Death in the Truffle Wood — Pierre Magnan

Banon is a small village in Provence, where the local community's principal source of income comes from the cultivation and sale of truffles. Outsiders rarely venture to this remote region, but a small group of society's dropouts have chosen to set up home on the outskirts of the village. Then one of them is found dead in the freezer of a local hotel. When a further five bodies are discovered hanging by their feet and drained of blood in the family vault of the cemetery, it takes all Commissaire Laviolette's considerable resources to unravel the crimes.
