How I Married a Marquess — Anna Harrington

A SHOCKING DECEPTION . . .
Josephine Carlisle, adopted daughter of a baron, is officially on the shelf. But the silly, marriage-minded misses in the ton can have their frilly dresses and their seasons in London, for all she cares. Josie has her freedom and her family . . . until an encounter with a dark, devilishly handsome stranger leaves her utterly breathless at a house party. His wicked charm intrigues her, but that's where it ends. For Josie has a little secret . . .

. . . LEADS TO AN EXQUISITE SEDUCTION
Espionage was Thomas Matteson, Marquess of Chesney's game-until a tragic accident cost him his career. Now to salvage his reputation and return to the life he loves, the marquess must find the criminal who's been robbing London's rich and powerful. He's no fool-he knows Josie, with her wild chestnut hair and rapier-sharp wit, is hiding something and he won't rest until he unravels her mysteries, one by one. But he never expected to be the one under arrest-body and soul . . .
