And he is stunned to learn that Helen may have been a collaborator in her own murder.Peeling back the layers of deception, Pendergast realizes that the conspiracy is deeper, goes back generations, and is more monstrous than he could have ever imagined-and everything he's believed, everything he's trusted, everything he's understood . . . may be a horrific lie.
