Devastated by the discovery that his wife, Helen, was murdered, Special Agent Pendergast will need to have retribution. But revenge is not basic. As he stalks his wife’s betrayers–a chase that requires him through the crazy moors of Scotland to the bustling streets of NEW YORK and the darkest bayous of Louisiana–he is also forced to dig further into Helen’s past. And he’s stunned to learn that Helen may have been a collaborator in her very own murder.

Peeling back the layers of deception, Pendergast realizes which the conspiracy is certainly deeper, goes back generations, and it is more monstrous than he could have ever imagined–and everything he’s thought, everything he’s trusted, everything he’s known . may be a horrific lay.
