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.

“A treasure of a book...An authentic adventure saga [and] a very human story generously seasoned with ingenuity, technology and hardy individualism.” —K9YA Telegraph Includes photos and maps Clandestine radio operators had one of the most dangerous jobs of World War II. Those in Nazi-occupied Europe for the SOE, MI6, and OSS had a life expectancy of just six weeks. In the Gilbert Islands, the Japanese decapitated seventeen New Zealand coastwatchers. These highly skilled agents’ main tasks were to maintain regular contact with their home base and pass vital intelligence back. As this meticulously researched book reveals, many operators did more than that. Norwegian Odd Starheim hijacked a ship and sailed it to the Shetlands. In the Solomon Islands Jack Read and Paul Mason warned the defenders of Guadalcanal about incoming enemy air raids, giving American fighters a chance to inflict irreversible damage on the Japanese Air Force. In 1944 Arthur Brown was central to Operation Jedburgh’s success delaying the arrival of the SS Das Reich armored division at the Normandy beachheads. The author also explains in layman’s terms the technology of 1940s radios and the ingenious codes used. Most importantly, Covert Radio Agents tells the dramatic human stories of these gallant behind-the-lines radio agents. Who were they? How were they trained? How did they survive against the odds? This is a highly informative and uplifting history of World War II’s unsung heroes.
