Nell Valenti is transforming the Villa Orlandini into a superb farm-to-table cooking school. But when Chef Orlandini prepares to reveal his top-secret marinara recipe to a group of American gastro-tourists, Nell realises she might have bitten off more than she can chew. One of the tourists is a private detective sent to spy on her by her father, and the fussy foodies are noisy and disrespectful from the start. Even worse, when one visitor is poisoned by the famous marinara recipe, Nell will have to work fast to uncover a killer before her fresh start is spoiled for good.
