Crops and robbers - Paige Shelton

Bailey's Farmer's Market is all abuzz with the impending visit of
the Central South Carolina Restaurant Association. Becca is quite
excited, especially since her parents are visiting. But when the
president of the Association vetoes Becca's strawberry preserves, she
finds herself reeling from the snub. After pulling herself together,
Becca heads home, only to find the president's body in her kitchen and
her mother with bloody hands. Now, Becca has to use her sleuthing
skills to get her mom out of this terrible jam...before she winds up
preserving in prison.
