As the proud proprietor and head pastry chef of Tea-by-the-Sea, a traditional English tearoom on the picturesque bluffs of Cape Cod, Lily Roberts' hands are full, often literally. But nothing keeps her busier than steering her sassy grandmother, Rose, away from trouble. Rose operates the grand old Victorian B&B adjacent to Lily's shop...for now. An aggressive real estate developer, Jack Ford, is pushing hard to rezone nearby land, with an eye towards building a sprawling golf resort that would drive Rose and Lily out of business.

Tempers are already steaming, but things really get sticky when Ford is found dead at the foot of Rose's property and the police think she had something to do with his dramatic demise. Lily can't let her grandmother get burned by a false murder charge. So she starts her own investigation and discovers Ford's been brewing bad blood all over town, from his jilted lover to his trophy wife to his shady business partners. Now, it's down to Lily to stir up some clues, sift through the suspects, and uncover the real killer before Rose is left holding the teabag.
