August in Taylorsford, Virginia finds library director Amy Webber and her new husband, dancer Richard Muir, settling into married life. But in this sixth outing (after A Deadly Case) an unknown woman's body turns up in Zelda Shoemaker's backyard gazebo. The police put Zelda at the top of the suspect list, thanks to a blackmail letter found in the dead woman's pocket. Complicating matters further, Amy unearths records of a long-ago tragedy that casts doubt on Zelda's innocence. She enlists the townsfolk to help exonerate Zelda, and meanwhile, the killer is still out there.
