Eliza Peabody is one of those dangerously blameless women who believes she has God in her pocket. She is too enthusiastic; she talks too much. Her concern for the welfare of her wealthySouth London neighbours extends to ingenuous well-meaning notes of unsolicited adviceunder the door. It is just such a one-sided correspondence that heralds Eliza's undoing. Did her letter have something to do with the woman's abrupt disappearance ? Why will no-one else speak of her?
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.
