Fallen Women Series by Loretta Chase

James Cordier is all blue blood and entirely dangerous. He's a master of disguise, a brilliant thief, a first-class lover—all for King and Country—and, by gad, he's so weary of it. His last mission is to "acquire" a packet of incriminating letters from one notorious woman. Then he can return to London and meet sweet-natured heiresses—not adventuresses and fallen women. Francesca Bonnard has weathered heartbreak, scorn, and scandal... moreJames Cordier is all blue blood and entirely dangerous. He's a master of disguise, a brilliant thief, a first-class lover—all for King and Country—and, by gad, he's so weary of it. His last mission is to "acquire" a packet of incriminating letters from one notorious woman. Then he can return to London and meet sweet-natured heiresses—not adventuresses and fallen women. Francesca Bonnard has weathered heartbreak, scorn, and scandal. She's independent, happy, and definitely fallen; and she's learned that "gentlemen" are more trouble than they're worth. She can also see that her wildly attractive new neighbor is bad news. But as bad as James is, there are others far worse also searching for Francesca's letters. And suddenly nothing is simple—especially the nearly incendiary chemistry between the two most jaded, sinful souls in Europe. And just as suddenly, risking everything may be worth the prize. less

"Spunky English girl overcomes impossible odds and outsmarts heathen villains." That’s the headline when Zoe Lexham returns to England. After twelve years in the exotic east, she’s shockingly adept in the sensual arts. She knows everything a young lady shouldn't and nothing she ought to know. She’s a walking scandal, with no hope of a future...unless someone can civilize her. Lucien de Grey, the Duke of Marchmont, is no knight in shining armor... more"Spunky English girl overcomes impossible odds and outsmarts heathen villains."

She knows everything a young lady shouldn't and nothing she ought to know. She’s a walking scandal, with no hope of a future...unless someone can civilize her. Lucien de Grey, the Duke of Marchmont, is no knight in shining armor. He's sarcastic, cynical, easily bored, and dangerous to women. He charms, seduces, and leaves them—with parting gifts of expensive jewelry to dry their tears. But good looks and charm, combined with money and rank, make him welcome everywhere. The most popular bachelor in the Beau Monde can easily save Zoe’s risque reputation...if the wayward beauty doesn't lead him into temptation, and a passion that could ruin them both. less
