On the night of the Parkhurst ball, someone had a scandalous tryst in the library.

Was it Lord Canby, with the maid, on the divan? Or Miss Fairchild, with a rake, against the wall? Perhaps the butler did it.

All Charlotte Highwood knows is this: it wasn't her. But rumors to the contrary are buzzing. Unless she can discover the lovers' true identity, she'll be forced to marry Piers Brandon, Lord Granville—the coldest, most arrogantly handsome gentleman she's ever had the misfortune to embrace.

When it comes to emotion, the man hasn't got a clue.

But as they set about finding the mystery lovers, Piers reveals a few secrets of his own. The oh-so-proper marquess can pick locks, land punches, tease with sly wit . . . and melt a woman's knees with a single kiss. The only thing he guards more fiercely than Charlotte's safety is the truth about his dark past.

Their passion is intense. The danger is real. Soon Charlotte's feeling torn. Will she risk all to prove her innocence? Or surrender it to a man who's sworn to never love?
