The richest of New York's rich gather at The Pierre's Cotillion Room to raise money for those less fortunate. A fatal blast rocks the room, stirring up horrifying memories of 9/11. Is the explosion an act of terrorism--or a homicide? A big-name female filmmaker is the next to die, in a desolate corner of New York City. Detectives Zach Jordan and Kylie MacDonald of the elite NYPD task force investigate, and the intimate details of the director's life remind them of their own impossible situation--their personal relationship seems as unsolvable as the murders. The crimes keep escalating as a shadowy killer masterfully plays out his vendetta--and threatens to take down NYPD Red in the bargain.
