A murderous Robin Hood stalks New York City in a powerhouse new thriller by the best-selling author of Black and White. Detective First Grade Brian McKenna and his partner Cisco Sanchez are chasing a killer that all of New York City is rooting for, a vigilante of supreme technical skill, physical power, and intelligence who signs himself "Justice." Justice is executing drug dealers, helping the police close unsolved cases, and providing those in need with stolen drug money—creating a nightmare for the police commissioner, the mayor, and the two detectives. McKenna and Sanchez must work to outsmart the killer, discover his next victim, and find out who is helping Justice in his quest for revenge.
