When an old Jesuit Mission House in Carthage, Ohio, is nominated for National Landmark status, the committee sends a private investigator to get to the bottom of the hostile letters they've received. Arriving in Carthage is Marian Warner, a New York PI whose life was dented by the bombing death-years ago-of her radical boyfriend. The only man with any staying power in her life is Charlie Levitan, the editor of the Carthage newspaper, whose relationship with her includes a long personal history. The day before Marian arrives, an older man nobody in town recognizes turns up dead in the Mission House.

Soon Marian discovers that the identity of the murdered man implicates every key player in the fight over the fate of the Mission House. But for her, it gets personal when Charlie's lover, a local jazz singer, is found murdered on the property of a powerful landmark preservationist, Jack Girard. What connects the two deaths? Why is a key witness avoiding her? How can she discover the truth in a town where hostilities go public, but secrets are so closely guarded? When Marian finally unmasks a cunning killer, it's at the expense of the defenses it's taken her years to erect.
