Boston P.I. Sunny Randall is facing the unthinkable: the marriage of her ex-husband, Richie, to someone else. Despite the formality of divorce, Sunny and Richie's relationship had continued, in its own headstrong way, until Richie's desire for marriage overtook Sunny's need for freedom. So when college student Sarah Markham comes asking for help in finding her birth parents, Sunny realizes she must take the case, if only to distract her from her personal life. But life and work have a curious - and dangerous - way of intersecting. Before the investigation has a chance to take off, two key players are dead and Sunny is back on a psychiatrist's couch, probing her own past for clues.
