When famed London courtesan Alessandra Northrope passes away, her daughter Celia Pennifold inherits little more than a hopelessly contaminated reputation, a house in a middle class neighborhood, and an education that prepared her to take her mother’s place the way Alessandra intended. Celia hopes to make her own life on her own terms, however, and moves into the house only to discover one more legacy—an enigmatic, handsome tenant who knows her mother’s plans for her future rather too well. Jonathan thinks he is on a simple mission to discover whether Celia’s mother left accounts of her lovers that might embarrass important men. Instead he finds himself embroiled in a mystery full of dangerous betrayals and secrets, old and new, that touch on his life as well as Celia’s.
