Gloucestershire, 1925. A week-long house party in the country—why not? Lady Adelaide has nothing else to do, now that her year of mourning for her unfaithful husband is up and her plans to rekindle her romantic life have backfired. But when her hostess is found dead on the conservatory floor, Addie knows just who to call—Detective Inspector Devenand Hunter of Scotland Yard.
Dev may not want to kiss Addie again, but he's anxious to solve the crime. Who would want to kill Pamela, the beautiful wife of one of Britain's Great War heroes? Certainly not her devoted and wheelchair-bound husband, Sir Hugh Fernald. The other guests seem equally innocent and improbable.
But despite all appearances, something is very wrong at Fernald Hall—there's a body buried in the garden, and the governess has fallen down the stairs to her death. Who's next? Addie and Dev must work together to stop another murder, and they have some help thanks to Rupert, Addie's late and unlamented husband. Rupert needs to make amends for his louche life on earth, and what better way to earn his celestial wings than catch a killer?
