Here is the ultimate inside history of twentieth-century intelligence gathering and covert activity. Unrivalled in its scope and as readable as any spy novel, A Century of Spies travels from tsarist Russia and the earliest days of the British Secret Service to the crises and uncertainties of today's post-Cold War world, offering an unsurpassed overview of the role of modern intelligence in every part of the globe. From spies and secret agents to the latest high-tech wizardry in signals and imagery surveillance, it provides fascinating, in-depth coverage of important operations of United States, British, Russian, Israeli, Chinese, German, and French intelligence services, and much more. All the key elements of modern intelligence activity are here. An expert whose books have received high marks from the intelligence and military communities, Jeffrey Richelson covers the crucial role of spy technology from the days of Marconi and the Wright Brothers to today's dazzling array of Space Age satellites, aircraft, and ground stations. He provides vivid portraits of spymasters, spies, and defectors--including Sidney Reilly, Herbert Yardley, Kim Philby, James Angleton, Markus Wolf, Reinhard Gehlen, Vitaly Yurchenko, Jonathan Pollard, and many others. Richelson paints a colorful portrait of World War I's spies and sabateurs, and illuminates the secret maneuvering that helped determine the outcome of the war on land, at sea, and on the diplomatic front; he investigates the enormous importance of intelligence operations in both the European and Pacific theaters in World War II, from the work of Allied and Nazi agents to the "black magic" of U.S. and British code breakers; and he gives us a complete overview of intelligence during the length of the Cold War, from superpower espionage and spy scandals to covert action and secret wars. A final chapter probes the still-evolving role of intelligence work in the new world of disorder and ethnic conflict, from the high-tech wonders of the Gulf War to the surprising involvement of the French government in industrial espionage. Comprehensive, authoritative, and addictively readable, A Century of Spies is filled with new information on a variety of subjects--from the activities of the American Black Chamber in the 1920s to intelligence collection during the Cuban missile crisis to Soviet intelligence and covert action operations. It is an essential volume for anyone interested in military history, espionage and adventure, and world affairs.

"The cumulative effect is overwhelming. Eleanor Roosevelt was right: Hoover’s FBI was an American gestapo." —Newsweek Shocking, grim, frightening, Curt Gentry’s masterful portrait of America’s top policeman is a unique political biography. From more than 300 interviews and over 100,000 pages of previously classified documents, Gentry reveals exactly how a paranoid director created the fraudulent myth of an invincible, incorruptible FBI. For almost fifty years, Hoover held virtually unchecked public power, manipulating every president from Franklin D. Roosevelt to Richard Nixon. He kept extensive blackmail files and used illegal wiretaps and hidden microphones to destroy anyone who opposed him. The book reveals how Hoover helped create McCarthyism, blackmailed the Kennedy brothers, and influenced the Supreme Court; how he retarded the civil rights movement and forged connections with mobsters; as well as insight into the Watergate scandal and what part he played in the investigations of President John F. Kennedy and Martin Luther King Jr.
