When Kit Kydd rescues Susanna Fair from an abduction attempt, it seems to be fate -- Kit needs to appear settled to be made his great-aunt's heir, and Susanna is an actress. By pretending to be engaged for the duration of a visit to Lady Penfold, Susanna will be hidden and Kit can protect her from further danger. But Lady Penfold lives in the horse-racing town of Newmarket, which holds the secret of Susanna's scandalous past. Meanwhile, the dishonorable Rafe Warwick has 2,000 guineas riding on making Susanna his mistress -- and he doesn't take defeat lightly.
