 It is the latest murder by a serial killer who has been terrorizing New York for 11 months.New York Mayor Flynn is frustrated with the lack of progress in tracking down the killer, and tells NYPD commissioner Frank Starkey to "get [his] brother, and get him now," as they both know Nick is the only man brilliant enough to catch this killer.This is a controversial assignment for Frank because two years earlier Nick was disgraced in a scandal and expelled from the force.
