Circle of Six is the true story of what is perhaps the most notorious case in the history of the New York Police Department. It details Randy Jurgensen's determined effort to bring to justice the murderer of Patrolman Phillip Cardillo, who was shot and killed inside Harlem's Mosque #7 in 1972, in the midst of an all-out assault on the NYPD from the Black Liberation Army. The New York of this era was a place not unlike the Wild West, in which cops and criminals shot it out on a daily basis.
Despite the mayhem on the streets and the Machiavellian corridors of Mayor Lindsay's City Hall, Detective Jurgensen single-handedly took on the Black Liberation Army, the Nation of Islam, NYPD brass, and City Hall, capturing Cardillo's killer, Lewis 17X Dupree. He broke the case with an unlikely accomplice, Foster 2X Thomas, a member of the Nation of Islam who became Jurgensen's witness. The relationship they formed during the time before trial gave each of the two men a greater perspective of the two sides in the street war and changed them forever. In the end, Jurgensen had to settle for a conviction on other charges, and Dupree served a number of years. The murder case is still officially unsolved. In 2006 the NYPD re-opened the case, and it is once again an active investigation with full media attention.
The book has received acclaim from current New York City Police Commissioner Ray Kelly, as well as former Commissioner William Bratton.
