Ambush - James Patterson

An anonymous tip about a crime in Upper Manhattan proves to be a set-up, taking an officer down-and it's not Michael Bennett.

The life of New York's top cop is not the only one at risk. One of Bennett's children sustains a mysterious injury. And a series of murders follows, each with a distinct signature, alerting Bennet to the presence of a professional killer.

Investigators chase leads that turn out to be phantoms, and this master killer entices one officer into compromising Bennett. He then goes a step further, luring another member of Bennett's family into even graver danger. Michael Bennett can't untangle what's driving the assassin-but he can tell it's personal. And he needs to determine exactly how he figures in the killer's logic, before there is one fewer Bennett in the world.
