Book excerpt: GAILLAC, SOUTH-WEST FRANCE. An unsolved case. Gil Petty, America's most celebrated wine critic, is found strung up in a vineyard, dressed in the ceremonial robes of the Order of the Divine Bottle and pickled in wine. An un-cracked code. For forensic expert Enzo Macleod, the key to this unsolved murder lies in decoding Petty's mysterious reviews - which could make or break a vineyard's reputation. An uncorked criminal. Enzo finds that beneath the tranquil façade of French viticulture lurks a back-stabbing community riddled with rivalry - and someone who is ready to stop him even if they have to kill again.
