But Stephen is a woman, and her lovers are women. As her ambitions drive her, and society confines her, Stephen is forced into desperate actions.
In the year 1780, Harriet Westerman, the willful mistress of a country manor in Sussex, finds a dead man on her grounds with a ring bearing the crest of Thornleigh Hall in his pocket. Not one to be bound by convention or to shy away from adventure, she recruits a reclusive local anatomist named Gabriel Crowther to help her find the murderer, and historical suspense's newest investigative duo is born.
