"Finding a murderer requires 100% proof. In Seneca Lake, New York, Norrie Ellington's Two Witches Winery has been selected by the local vintner community to host the annual Federweisser, a celebration of the season's first fermentation of white Chardonnay grapes. But the festivities are spoiled when Norrie learns that landowner Roy Wilkes has raised her neighbor Rosalee Marbelton's rent so high, she may have to close her vineyard. Before the rent hike could go into effect, Wilkes is found dead on Roslaee's property--stabbed by a flowerpot stake--and she becomes the police's number one suspect. To clear her friend's name, Norrie conducts her own investigation. But as she gathers clues, Norrie finds herself targeted by a killer, and if she's not careful, her desire to see justice done may die on the vine . . . "
