Hyacinth Bridgerton agrees to translate an Italian diary for Gareth St Clair, whose inheritance is threatened by a hostile father and a disputed family history. Their search for clues turns an intellectual partnership into a courtship conducted through argument, curiosity and shared risk.

The mystery behind the St Clair estate gives Hyacinth a problem worthy of her confidence and sharpness, while Gareth must decide how far blood and legitimacy define him. The novel combines romance with a domestic inheritance puzzle in the London society of the mid-1820s.
