Treble at the Jam Fest (Food Lovers' Village Mystery, 4)

Erin Murphy, manager of Glacier Mercantile (a.k.a. the Merc), is tuning up for Jewel Bay's annual Jazz Festival. Between keeping the Merc's shelves stocked with Montana's tastiest local fare and hosting the festival's kick-off concert, Erin has her hands full. Discord erupts when jazz guitarist Gerry Martin plummets to his death from the rocks above the Jewel River. The one-time international sensation had fallen out of sync with festival organizers, students, and performers. Was his death an accident-or did someone even the score? Erin investigates despite the warning signs not to get involved. And when the killer attacks, she orchestrates her efforts into one last crescendo, hoping to avoid a deadly finale.
