With Emily Westhill’s popular Deputy Donut Café rolling out seasonal summer treats, everyone in Fallingbrook, Wisconsin wants a taste. But when a limited batch box turns up near a dead body, Emily and her curious tabby are pitted against the worst kind of customer—a cold-blooded murderer!

Emily feels like a protective big sister around bubbly twenty-something Izzy—a new regular whose enthusiasm for peaches and cream donuts is surpassed only by her dream to start her own business. As if blown in by an August breeze, Izzy pulls Emily into her plan to buy a property at the edge of town to grow and sell fresh produce. But she’s not the only fan of Deputy Donut’s peachy delights . . . or the only patron vying to own the lush parcel of land. And the competition is fiercer than the two women imagined . . .

Petty squabbles turn deadly when a developer with a mean streak is found murdered on the vacant stretch of land. Worse, Emily’s signature donuts are spotted nearby, leading to several potential suspects who could have left their sugar-frosted fingerprints all over the crime scene—including the mayor, a handsome out-of-towner, and even sweet-to-the-core Izzy. When her detective husband discovers poisonous ingredients in the discarded desserts, a shocked Emily must reveal holes in a collection of very fuzzy facts and nab the killer before someone else takes their last bite . . .
