Gaillac, southwest 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 uncracked 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 backstabbing community riddled with rivalry - and someone who is ready to stop him even if they have to kill again.
