THE THREAT MATRIX is the story of a small group of FBI agents who believed that they could confront a new generation of international terrorists like al Qaeda without sacrificing America's moral high ground. At the heart of this classic good versus evil battle are decades of tensions between the FBI and the CIA, which repeatedly fell short as America's eyes overseas. Given unprecedented access, thousands of pages of once secret documents, and hundreds of interviews, Garrett M. Graff takes us inside the FBI and its attempt to protect America. From the corridors of the Hoover Building to the cells of Gitmo and the mountains of Afghanistan and Pakistan, Graff tells the true story of how a generation of FBI agents taught themselves to confront threats no one had ever seen before. Brilliantly reported and suspensefully told, THE THREAT MATRIX peers into the darkest corners of this secret war and will change your view of the FBI forever.
