Love and murder make a marriage of convenience inconvenient at best

Dorothy Stainton is determined that her younger sister marry the man of her choosing. Unfortunately, to pay a debt, their aunt arranges a marriage between Dorothy and the Earl of Arundell, the man rumored to have murdered his elder brother for the title.  When Dorothy refuses, Aunt Mary threatens to marry Grace to the earl.

Left with no choice, Dorothy agrees to marry Arundell. When she meets him, her immediate attraction to him wars with her fear that the rumors may be true. A desperate game of deception begins when she discovers that he is searching for his niece, who escaped the night her parents were killed. Despite the whisperings of her treacherous heart that Arundell is innocent, Dorothy searches for the girl in hopes that she can prevent another tragedy and find the truth.
