The Secret Sentry: The Untold History of the National Security Agency
"This, very simply, is the most informative book ever written on the inside bureaucratic struggles and the outside operations of the National Security Agency. Matthew Aid is our reigning expert on the NSA."—Seymour M. Hersh, author ofChain of Command: The Road from 9/11 to Abu Ghraib “NSA analysis now comprises as much as 60 percent of the president’s daily intelligence briefing, and Aid provides a critical history of the agency that has the ear of the leader of the free world. A sprawling but revealing look at a powerful, shadowy agency of the American government.”—Kirkus
