After five years on foot patrol inside the idyllic Tuscan walled city of Siena, Italy, Ali Falco is eager to stretch her limbs into the surrounding region and prove her worth in her new role of detective. Still recovering from gunshot wound surgery after the events up north in Como, she gets her chance sooner than expected when a man is found murdered inside his family vineyard home in the wine country of Montalcino. The death of the young vintner is a devastating blow to a father and sister, surviving owner-operators of a winery producing the iconic style of wine: Brunello di Montalcino. Wounds point to a killer bent on vengeance, but for what? As motive for the killing proves just as elusive as the identity of the murderer, the case leads Ali and her partners to rich and powerful people in the area, whose bloodlines span back generations, and whose money flows like wine into the pockets of those in power. Young Detective Falco finds herself in over her head amid such a crowd, and the closer she gets to the truth, the more danger she finds herself running from. With death looming at the final turn, will Ali's first case be her last?
