In Banon, a small, peaceful village in upper Provence, the local community's principal source of income is the cultivation of truffles. Outsiders rarely venture to this remote region, but a small group of society's drop-outs have chosen to set up home on the outskirts of the village, and trouble ensues.

When one of them is found dead in the freezer of a local hotel, and when a further five bodies are discovered drained of blood in a family vault in the cemetery, it takes all Commissaire Laviolette's considerable resources to unravel crimes that have been committed in a climate of age-old superstition and secret animosity.

Not since Jean Giono has any writer been able to capture the authentic flavour, spirit and traditions of Provence.
