Detective Gary Mitchell and psychic Dan Porter have a new cold case to tackle, and new leads to research in the hunt for Gary's brother's killer. Their life in Boston has settled into a comfortable rhythm.

But when forensic discoveries in a recent robbery gone wrong share similarities with their three-year-old cold case, all they can do is follow the evidence-and Dan's gift-which leads them in an unexpected direction, way out of their comfort zone.

Gary and Dan find themselves in a shadowy world where they can trust no one, with unseen opponents who want them to back away from their investigation-and suddenly they're in a race they have to win.

Because if they don't, the consequences could be more far-reaching than they could possibly imagine.
