Title: A crime of manners
Description: SHE WAS AN AUDACIOUS MISS--AND CLEARLY EVERYTHING HE DIDN'T WANT!
Giles Vayne, the eighth Duke of Winterton, was rich, handsome, and arrogant enough to assume that every eager mother was throwing her daughter at him. He was right, of course. Unfortunately that cynicism, plus an ill-mannered comment, made a charming country miss the subject of town scuttlebutt before her first ball!
True, Henrietta Lanford had dreamed endlessly about his lordship--until his scandalous comment fueled her ire and her brazen public rebuke delighted the gossips to no end. She decided to encourage the attentions of another, unaware of his lascivious designs.
Soon scheming and seduction of all sorts compelled Giles to become her reluctant protector, as fair Henrietta discovered that the hero of her fantasies was quite real indeed.
