The options for the penniless daughter of a deceased Earl are few indeed in Regency England. So, following the suspicious death of her father, the Earl of Morton, and the discovery that she and her much younger sister have been left without income or home, Lady Caroline takes a post as a lady's companion to the wealthy widow Frogerton. Just as Caroline is getting accustomed to her new position, her aunt, Lady Eleanor Greenwood, invites her and her employer to a house party. Mrs Matilda (Matty) Frogerton sees this as an opportunity to introduce her own rather wild daughter, Dorothy, to the ton, and Caroline is eager to see her sister, who as a child lives with their aunt. But all is not well at the Greenwood estate. For one thing, Lady Caroline's former fiance, Lord Francis Chatham, is a guest and refuses to speak to her. Far worse, an elderly family member is found stabbed by a knitting needle.

Set against the timelessly intriguing backdrop of 1830s high-society London, this delightful historical mystery series features Miss Caroline Morton, daughter of a disgraced earl, now gainfully employed as a lady’s companion—along with a sideline in sleuthing . . . 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 . . .
