""A deadly search for sour grapes . . . Norrie Ellington is a successful screenwriter living in New York City. She's also been a silent partner for her family's winery upstate-until her sister and brother-in-law take a year-long sabbatical. With an experienced staff doing the work, Norrie figures Two Witches Winery will run itself while she enjoys the countryside and writes in peace and quiet. Unfortunately, there's a sour grape in the town of Penn Yan who doesn't care for vineyards. Bed and breakfast owner Elsbeth Waters complains to everyone who'll listen that the local wineries are bad for her business. But when Elsbeth's body is found on Norrie's property, the victim of foul play, the screenwriter-turned-vintner dons a sleuthing cap to uncover the identity of a killer who told the B&B proprietess to put a cork in it-permanently . . .
