The Bliss — Jacqueline Navin

Morgan Gage is no longer welcome in the houses of Polite Society--not since the murky circumstances of his father's untimely death all pointed to Morgan as his murderer. Once considered a most eligible bachelor, he is now referred to as "the Wicked Earl of Waring." Even though he has never cared one whit for l'opinion du beau monde, Morgan knows that his life cannot return to normal until he clears his name. And for that, he'll need a plan...

With her charm and beauty, Miss Leah Brodie has the entire ton wrapped around her delicate finger. But in an odd twist of fate that brings these two together, Miss Brodie shows Morgan her darker side, one that is decidedly unladylike: the Earl can hardly mask a wry smile at the sound of his captive's string of oaths. It dawns on him that he has found the perfect partner for his plot: because her reputation, like his, was once marred by scandal, each one can help the other.

It is supposed to be a mere business arrangement, one from which they will both benefit, but neither counted on falling in love.
