Case Devere, the steely-eyed earl of Castleton, has agreed to help Special Branch track down a notorious killer—one who just happens to be his archenemy. But he finds more than he bargained for when his search leads him to Jane Mayberry, a beautiful bluestocking passionately devoted to the cause of women’s rights—and to protecting her privacy. As irresistible as she is uncooperative, the spirited Jane arouses Case’s interest—as well as his worst suspicions—when she quietly disappears. Determined to find the one woman who may hold the key to his investigation—and to his heart—Case goes after her.

Though their sparring belies an attraction too powerful to deny, Jane knows there can never be anything between herself and the strong-willed earl. For she bears a dark and terrifying secret that must remain hidden—even at the cost of a broken heart. As Case fights for the love of the one woman who has ever mattered to him, they are swept into a deadly game by a killer who won’t stop until he has punished them both.
