Ewan McLean promises to right the wrong done by his uncle twenty years ago.
The Earl of Lyndale, Duncan McLean, was an honorable hellraiser throughout his life. The old earl swore that he had never cheated a man, lied to a woman or failed to protect an innocent. His only regret was an incident involving a man named Angus Cameron. When he learns he's dying, the earl summons his nephew and makes him promise to make things right with Cameron. With a rogue’s reputation and a courtier’s charm, Ewan is a man after his uncle’s rakehell heart.
A handsome rogue, Ewan's hobbies are seduction and gambling. It was whispered in ballrooms throughout London that Ewan McLean could seduce any woman with a heartbeat and convince a miser to wager his last sixpence. But he has never ruined a maiden or gambled with a man who couldn't afford to lose. He also collects risque Renaisance art. His collection of erotic statues is the scandal of London.
Ewan has friends in government circles who ask him to put his expertise to good use. Some surprisingly good art forgeries have recently been circulated in and around London. Ewan agrees to investigate as soon as he takes care of a prior obligation; the promise he made to his dying Uncle. He doesn’t think it will take long. Ewan has never met anyone he couldn’t convince to do whatever he wanted. Then again, he’s never been to the highlands.
When Ewan travels to Scotland to fulfill his promise, he discovers that Angus Cameron died years ago leaving behind four daughters; dreamer Ann, practical Joan, romantic Mary and Bride, the eldest. Bride Cameron is brilliant, beautiful and belligerent. When he introduces himself as the new Earl of Lyndale, she tells him he has no authority across the border and orders him off her property. Taking her hostility in stride, Ewan offers to move the Cameron sisters to his London estate. With skirmishes breaking out between ambitious english lords and rebellious scotsmen, the highland border is no place for four young women on their own. He feels he should keep a closer eye on his beautiful charges, especially Bride. The younger three sisters seem willing but Bride objects to his arrogant attitude and tells the new earl to mind his own business. She insists that she can take care of herself and her sisters. Ewan thinks she’s just being stubborn and refuses to leave until he makes sure Bride and her sisters are adequately provided for.
Bride isn’t foolishly proud; she’s afraid Ewan will uncover the family secret. Her father was an expert engraver who specialized in Renaisance reproductions. He also dealt in counterfeit bank notes. In his younger days, Angus travelled to war torn villages scattered around the border and provided funds to starving families. Bride promised her dying father she would continue the family tradition. Unfortunately, several of the plates disappeared over a year ago; coincidently near the time Bride’s former lover departed for places unknown. Bride knows all about young rogue’s promises.
But she doesn’t know much about the man London society has dubbed the Lord of Sin.
