In the charming tourist town of Mulbury, Rosemary Exeter thought the most excitement she'd face was deciding between quince jelly and lemon marmalade for her shop's window display. But when a first-aid training session takes a deadly turn, the autumnal peace is shattered.

Two rival groups descend upon the town like vultures, each with supernatural intent. Meanwhile, local businessman Robert Sparkling finds himself caught in a vicious family feud with his brother William—a battle over their late father's will that's turning brother against brother. And something's up with Rakisha whose earthly connectiveness has abandoned her in the face of meeting someone from her past.

As Rosemary delves deeper into the mystery, armed with nothing but her keen wit and an uncanny ability to read people like jam labels, she discovers the supernatural investigators know much more about the delusional widow than anyone first realized. The truth is far more sinister than any ghostly story.

In a town where secrets simmer beneath the surface, Rosemary must untangle a web connecting ghost hunters, inheritance disputes, and murder. Even with her eclectic friends on her side, she'll need every ounce of cunning to catch the killer and save Mulbury.

Can Rosemary preserve more than just fruit in jars?
