Then Phate delivers a huge blow, murdering one of the division's own, a "wizard" who pioneered the internet and the search takes a zealous intensity. Gillette and Detective Frank Bishop, ab old-school homicide cop who's accustomed to forensic sleuthing, at first make an uneasy team. But with a merciless and brilliant killer like Phate in there crosshairs, and his twisted game reaching a fever pitch, they must utilize every ounce of there disparate talents to stop him.
