murder mystery. Meet the Bright Young Things, the rabble-rousing hedonists of the 1920s whose treasure hunts were a media obsession. One such game takes place at the 18th birthday party of Pamela Mitford, but ends in tragedy. The police quickly identify the killer as a maid, Dulcie. But Louisa Cannon, chaperone to the Mitford girls and a former criminal herself, believes Dulcie to be innocent, and sets out to clear the girl's name . . . all while the real killer may only be steps away.
