The Puzzle Palace
Inside the National Security Agency, America's Most Secret Intelligence Organization

In this remarkable tour de force of investigative reporting, James Bamford exposes the inner workings of America's largest, most secretive, and arguably most intrusive intelligence agency. The NSA has long eluded public scrutiny, but The Puzzle Palace penetrates its vast network of power and unmasks the people who control it, often with shocking disregard for the law. So sensitive was the information uncovered that the agency twice attempted to suppress the book, threatened the author with prosecution, and even raided one of the libraries he used. This is a brilliant account of the use and abuse of technological espionage.
