Restaurateur Robbie Jordan is ready for the boost in business a local music festival brings to South Lick, Indiana, but the beloved event strikes a sour note when one of the musicians is murdered . . . June's annual Brown County Bluegrass Festival at the Bill Monroe Music Park in neighboring Beanblossom is always a hit for Robbie's country store and cafe, Pans 'N Pancakes. This year, Robbie is even more excited, because she's launching a new bed and breakfast above her shop. A few festival musicians will be among Robbie's first guests, along with her father, Roberto, and his wife, Maria. But the celebration is cut short when a performer is found choked to death by a banjo string. Now all the banjo players are featured in a different kind of lineup. To clear their names, Robbie must pair up with an unexpected partner to pick at the clues and find the plucky killer before he can conduct an encore performance . . .
