Marianne wakes with no memory and no idea who she is or where she was going — a name on her brooch the only clue to her identity. Lost, penniless, and convinced she's being followed, she pleads for help at the nearest village and is taken in by a lonely widow at her grand country home, Maulever Hall.
An unexpected visit from the widow's aloof son and his soon-to-be-betrothed, Lady Heverdon, leaves Marianne desperate for answers. They suspect Marianne has come into their lives under false pretences, but, the longer she spends with Lady Heverdon, the more Marianne becomes convinced that the opposite may be true.
