Even though Sally Stuart’s Aunt Maggie may have been a trial sometimes, what with her endless talk about genealogy, surely no one could have wanted to kill her! Yet it’s Aunt Maggie whom Sally finds strangled in the back passageway at Wisteria Hall, the stately antebellum mansion outside Roswell, Georgia, where she and her husband, Bill, are holding a house party to celebrate the engagement of beautiful Claire Harper and handsome Bob Dunbar.
Things go from bad to worse after Sally stumbles across Aunt Maggie’s dead body. Wisteria Hall is cut off from civilization, as a thunderstorm hits, the phone line is cut and the automobile tires are punctured. The house party hosts, guests and servants have a dark night ahead of them, and, contrary to what they say, it doesn’t always get brighter with the dawn. Can Sally find who killed Aunt Maggie—and not get killed herself?
