Queen's Gambit — Andrew G. Nelson

For retired NYPD detective, James Maguire, hunting Keith Banning was like trying to catch a ghost. In the six months since the two men had first battled to a stalemate, Maguire has spent countless hours chasing down leads and sightings of the elusive serial killer, only to watch them slip away at the very last moment. For Maguire, and the state police task force charged with capturing Banning, it is as if the man had never even existed. Now Maguire's old friend, Richard Stargold, has been appointed as the new NYPD police commissioner, and is offering James the opportunity to return to the department he loves. While the specter of Banning remains ever present, now an even greater danger looms just ahead on the horizon, a threat which will put even more lives at risk. In a game driven by revenge, how much will be sacrificed to win? The clock is ticking.
