Cold Vengeance (Agent Pendergast)

Devastated by the discovery that his wife, Helen, was murdered, Special Agent Pendergast must have retribution. But as he stalks his wife's betrayers - a chase that takes him from the wild moors of Scotland to the bustling streets of New York City and the darkest bayous of Louisiana - he is also forced to dig further into Helen's past. And he is stunned to learn that Helen may have been a collaborator in her own murder. Everything he's trusted, everything he's understood may be a horrific lie.
