Mrs Laetitia Rodd, aged 52, is the impoverished widow of an archdeacon - who just so happens to make her living as a private investigator. Her brother, Frederick Tyson, finds the cases, and Mrs Rodd solves them, using her arch-intelligence and iron discretion. When Frederick brings her a case involving the son of the highly connected Sir James Calderstone, Mrs Rodd heads to Lincolnshire, to pose as the family's new governess. But the seemingly simple case - looking into young Charles Calderstone's inappropriate love interest - soon takes an unpleasant turn, and as the family's secrets unfold, Mrs Rodd discovers the Calderstones have more to hide than most.
