Johanna Lindsey takes us back to Regency England in another romantic farce starring the Malory clan. The story begins when London's most handsome and eligible bachelor, Jeremy Malory, hires himself a thief to help a friend recover some jewelry he was cheated out of. The thief Jeremy forcibly hires is 20-year-old Danny, who is really a woman masquerading as a man. When she was 5, Danny's home was broken into, and everyone in it but her and the nurse she escaped with was murdered. Danny has no memories of anything before she was rescued by a young prostitute in an alley after her nurse died, and has been masquerading as a man to avoid a fate of prostitution for herself. Jeremy, a seducer of women, notices right off that she's no man, and it's simply in his nature to try to talk her into bed. Danny escapes his clutches, but winds up coming to him for a job when she gets kicked out of the house where she's been living. Jeremy sees it as his opportunity to seduce her, and is quite perplexed when she refuses to become his mistress, preferring to work as a maid instead.

Jeremy has vowed to never get married, and finds himself in a fix when a young debutante schemes to get him to the altar. Danny saves the day by dressing up and posing as his fiancée, and soon after, she falls into bed with Jeremy, though she still refuses to become his mistress. Her one appearance at a ball with Jeremy has put her in danger, though, because she looks so much like her mother that the man responsible for her family's murders takes note and decides to have her done in for good. Jeremy saves her, of course, and falls in love with her, too, since she's so much different than any woman he has ever known. Danny also finds out who she really is in the end, too, and everyone lives happily ever after.
