Autumn in Arbordale brings crisp air, vibrant leaves, and the bustling energy of harvest season. But the festive mood shatters when Isla Reed discovers the body of a young farm worker sprawled lifeless on a vintage Davenport at Mrs. Bailey's barn. What looks like a tragic fight gone wrong quickly turns into something darker—a sinister game of revenge and secrets.

Enlisted to help prove the suspect innocent, Isla dives headfirst into the tangled web of rural drama, jealous lovers, and an uncertain motive. But the closer she gets to the truth, the more personal the danger becomes. Someone wants Isla to abandon her investigation, and they're willing to threaten more than just her Peace of Mind.

With the help of Higgins, her mischievous cat, and the ghostly guidance of her eccentric Aunt Daphne, Isla must solve this deadly puzzle before the killer decides she's learned too much. But under the glow of the harvest moon, danger lurks closer than she thinks, and the next victim could be her.
