It's the Fourth of July in 2017 when this mystery starts with a bang. Maureen Donahue, a Black Lives Matter filmmaker and speaker at the historic Chautauqua Institution, is killed at a raucous holiday concert -- amid the orchestra's roar and audience's popping paper bags, to simulate cannon fire at the end of Tchaikovsky's "1812 Overture." A stalker who followed Donahue to Chautauqua, a peaceful, leafy, cottage-filled, lakeside summer arts community, is quickly arrested. The stalker's brother asks Mimi to help clear him. She's skeptical. She has her own wedding to plan. But, of course, the reporter and relentless snoop, can't resist. With help from her computer-savvy son Jake, Mimi sifts through layers of secrets -- of a shadowy piano teacher, a racist personal trainer and chatty chime-master, among others -- and realizes: she's been asking all the wrong questions. The right ones unearth an ugly buried secret that puts Mimi close, maybe too close, to the real killer. Fans of Agatha Christie and Louise Penny and "Only Murders in the Building" will enjoy this twist-filled mystery calls, "An engaging mystery with a late twist and an especially satisfying ending."
