Twenty years after a girl is handed over to a shadowy man claiming to be her father, she reappears in the wake of a series of grisly murders, prompting near-retirement Inspector Carus Groves and disillusioned metaphysics professor Thomas McKnight to investigate.

As gravestone expert Sweeney St. George tours burial sites of the Civil War, she stops to watch a battlefield reenactment in Massachusetts. There, she meets Pres Whiting, a boy whose family is in the gravestone business. When Pres discovers a dead man in a Revolutionary War-era British soldier's uniform, Sweeney and Cambridge homicide detective Tim Quinn jump on the case. While they search for clues regarding the dead body, Sweeney and Quinn investigate other strange events. While Sweeney looks into the 1775 disappearance of militiaman, Quinn looks into a current missing persons case with alarming ties to the past. As they try to uncover how their own investigations are related to the body found in the woods, Sweeney and Quinn get a little too close for comfort -- to each other and to murder.

Author Cassandra Fallows has achieved remarkable success by baring her life on the page. Her two widely popular memoirs continue to sell briskly, acclaimed for their brutal, unexpurgated candor about friends, family, lovers—and herself. But now, after a singularly unsuccessful stab at fiction, Cassandra believes she may have found the story that will enable her triumphant return to nonfiction. When Cassandra was a girl, growing up in a racially diverse middle-class neighborhood in Baltimore, her best friends were all black: elegant, privileged Donna; sharp, shrewd Tisha; wild and worldly Fatima. A fifth girl orbited their world—a shy, quiet, unobtrusive child named Calliope Jenkins—who, years later, would be accused of killing her infant son. Yet the boy's body was never found and Calliope's unrelenting silence on the subject forced a judge to jail her for contempt. For seven years, Calliope refused to speak and the court was finally forced to let her go. Cassandra believes this still unsolved real-life mystery, largely unknown outside Baltimore, could be her next bestseller.
