Lady Caroline is happy to be back amid the swirl of London society, guiding her employer’s daughter, Dorothy Frogerton, through her first Season. Declared “an original” by a patron of the exclusive social club, Almack’s, Dorothy is sifting through potential suitors. Mrs. Frogerton, meanwhile, finds her own diversions, including spiritualist gatherings at the home of Madam Lavinia, and begs Caroline to come along. Caroline is skeptical of Madam’s antics and faux French accent—until she slips a note into Caroline’s hand, which contains intimate family knowledge. Even as Caroline tries to discern whether the spiritualist’s powers are real, a much darker mystery presents itself: Madam Lavinia is found lifeless in her chair, a half-empty glass of port at her elbow. In her desk is a note addressed to Caroline, entreating her to find her murderer. Caroline needs no psychic abilities to determine a motive, for it seems that Madam was blackmailing clients and has left a trail of aggrieved aristocrats behind. But as Caroline and Mrs. Frogerton investigate further, they find other suspects, and deceptions, some very close to home. Now Caroline must keep all her wits about her if she is to stop others from joining Madam Lavinia in the afterlife . . .
