When a local bluegrass musician disappears and a jug of her shop's corn liquor is implicated, moonshiner Hattie Hayes must stop further trouble from brewing in this delightful cozy mystery series. It's late August in Chattanooga, Tennessee, and moonshiner Hattie Hayes has collaborated to serve her moonshine at a nearby vineyard for a Wine and 'Shine event. Not only is this an opportunity for Hattie to gain more moonshine fans, but she's also excited to see the Bootlegging Brothers, a popular bluegrass band. But not every attendee is looking for harmony, and when one of the brothers disappears after the event and is presumed dead, Hattie realizes her grace note event has suddenly turned more sour than her mash. Unearthing what happened to the missing musician is more difficult than Hattie first expected, and when Hattie's moonshine is tied to the crime, there's no time to fiddle around. She has to step up to solve the case. Luckily, Hattie's cool head and quick mind help her understand that when investigating a musical crime, always stay sharp.
