The dark vineyard / Martin Walker.

Enhanced descriptions from Syndetics:

In this riveting sequel to Martin Walker's internationally acclaimed novel Bruno, Chief of Police, some of France's great pleasures--wine, passion and intrigue--converge in a dark chain of events that threaten the peaceful village of Saint-Denis.

Benoît (Bruno) Courrèges--devoted friend, cuisinier extraordinaire and the town's only municipal policeman--rushes to the scene when a research station for genetically modified crops is burned down outside Saint-Denis. Bruno immediately suspects a group of fervent environmentalists who live nearby, but the fire is only the first in a string of mysteries centering on the region's fertile soil.

Then a bevy of winemakers descends on Saint-Denis, competing for its land and spurring resentment among the villagers. Romances blossom. Hearts are broken. Some of the sensual pleasures of the town--a dinner of a truffle omelette and grilled bécasses, a community grape-crushing--provide an opportunity for both warm friendship and bitter hostilities to form. The town's rivals--Max, an environmentalist who hopes to make organic wi≠ Jacqueline, a flirtatious, newly arrived Québécoise; and Fernando, the heir to an American wine fortune--act increasingly erratically. Events grow ever darker, culminating in two suspicious deaths, and Bruno finds that the problems of the present are never far from those of the past.

A splendid mystery--and a delectable serving of the pleasures of France.
