In The Forever Prisoner, authors Cathy Scott-Clark and Adrian Levy describe dramatic events that took place in numerous black sites around the world through the eyes of those who were there. They also trace the perverse legal justifications and show how enhanced interrogation, a key "weapon" in the global "War on Terror," spread over a period of seven years, affecting dozens of detainees in various locations, some of whom died. In the end, the war cost 8 trillion dollars, claimed 900,000 lives, and forced the displacement of 38 million people?all while enhanced interrogation was deemed torture by the U.S. Senate and failed to yield any high-value intelligence. Contrary to American values of justice and due process, several men, including Abu Zubaydah, continue to be detained in Guantanamo despite never having been charged with a crime. This is because their trials would make public the horrible cruelty they endured.
