Some Like to Shock [EPUB ebook] 

A rakish agent of the Crown teams up with a dowager duchess to accomplish his mission in this Regency romance by a USA Today-bestselling author."Surely a lady as . . . daring as you cannot be feeling nervous at the idea of traveling alone with me, Genevieve?"Genevieve Forster, widowed Duchess of Woollerton, knows only too well the need for bravado. After a miserable marriage she’s wary, but deep down yearns to pursue temptation. . . .With his air of danger and elusiveness it’s little wonder that Lord Benedict Lucas is known to his close friends and enemies alike simply as Lucifer. Shocking the straitlaced Ton holds no fear for him. And the pleasure will be all his as he skillfully uncovers Genevieve’s outrageous side!
