The President is Missing. Detective Michael Bennett's enemies know where to find him.
An anonymous tip about crime in Upper Manhattan proves to be a setup. An officer is taken down - but despite the attackers' efforts, it's not Michael Bennett. New York's top cop is not the only one at risk.
One of Bennett's children is attacked. And a series of murders follows, each with a distinct signature, alerting Bennett to the presence of a professional killer. Bennett can't tell what's driving the assassin.
