Here, from New York Times bestselling author Robert Daley is the true story of a cop who knew too much. In the 1970s, the federal government investigated the corruption penetrating the entire criminal justice system in New York City, particularly the Special Investigations Unit (SIU) of the Narcotics division of the NYPD. Detective Robert Leuci was chosen by federal prosecutors Rudolf Giuliani, Maurice Nadjari, and Tom Puccio to probe this world of corruption as an undercover agent. Operating in deep cover, with only the prosecutors and the NYPD commissioner aware of his dual role, Leuci walked a tightrope that made his life a nightmare. He was in mortal danger from both sides. In a world where conflicting pressures are excruciating, who should bear the burden of being right when so much of the system is wrong?
