Animated by a passion for food, wine and justice, the Gourmet Detective travels to Provence to investigate a shadowy business deal between two vineyards. But before he can even sample the delights of Pate de Grives on triangles of hot, crisp toast, he encounters a corpse leaning against a cart in the vineyard. Was he really gored to death by sangliers, wild boars rumoured to live in the abandoned caves surrounding the village? And why would a tiny vineyard want to buy out its enormous neighbor - and competitor - at any price?
