An octogenarian sleuth must solve the murder of a local florist before the killer buries the truth. Myrtle Clover and her sidekick Miles are drawn into a Valentine's Day murder when florist Teddy Hartfield is found dead. The investigation leads them through a garden of suspects, including Teddy's sister, a disgruntled developer, and a former business partner. As they dig for clues, they must navigate a dangerous path where the killer is determined to keep the truth hidden.

The premise sets up a classic cozy mystery with a charming elderly protagonist and a small-town setting. The inclusion of specific suspects like a jealous sister and a disgruntled developer suggests a focus on interpersonal relationships and local secrets. The narrative appears to prioritize puzzle-solving and character interaction over intense action or graphic violence, typical of the genre. The Valentine's Day theme adds a seasonal element that may influence the atmosphere and character motivations.
