From noted intelligence authority and author Chapman Pincher comes an utterly riveting book that reveals in startling detail sixty years of Soviet spying against Great Britain and the United States. Using a huge cache of recently released documents and exclusive interviews, Pincher makes a compelling new case that–as he has long believed–the head of Britain’s own counterintelligence and security agency was himself a double agent, acting to undermine and imperil the U.K. and America. Written with the power of a heart-pounding thriller, Treachery pulls the mask from intelligence leader Roger Hollis. As a result, years of traitorous action and inaction on his watch come tumbling down. Pincher reveals Hollis’s early years, when he was schooled at Oxford, which “educated” many agents, and worked in 1930s Shanghai, a hotbed of soon-to-be spies and Soviet recruiters. Hired by MI5–at a time when there was virtually no vetting of employees–he was a gray presence who rose in the ranks over twenty-seven years while, Pincher suspects, he was allowing the most notorious Soviet spies of the century to flourish. Myriad fascinating case histories are portrayed here, including that of Lt. Igor Gouzenko, a Red Army cipher clerk who said cryptically in 1945 that there was a mole in MI5 with access to important files. Pincher also provides exciting new perspectives on the most infamous operatives of our time, including Kim Philby and Klaus Fuchs. Perhaps most explosively, Pincher posits that long after Hollis stepped down, a cover-up was perpetrated at the highest levels, and that Margaret Thatcher was induced to mislead Parliament to prevent the truth from coming out. An essential volume for a world potentially facing a new cold war as Russia dangerously flexes its military and espionage muscles once again, Treachery warns us to protect our society and institutions from enemy infiltration in the future. This is a revelatory work that puts twentieth-century politics and war into stunning new relief. “Chapman Pincher has drawn on decades of research and mined fresh evidence to examine in depth one of the enduring and controversial mysteries of the Cold War: was the chief of the British security service a Soviet spy?” —David Wise, The Invisible Government Chapman Pincher is the most experienced and perhaps the best-known British espionage writer. Born in India in 1914, he was educated at King’s College London and the Royal Military College of Science. His book Their Trade Is Treachery, which first charged Sir Roger Hollis with being a Soviet agent, was a sensation. For decades he has been the most effective critic of the British security system, and over the years he has broken scores of stories that have created headlines. Chapter One A Momentous Message Late in the year 2000, vladimir putin, president of the Russian Federation, awarded the posthumous title “Superagent of Military Intelligence” to Ursula Beurton, a former British housewife who is better known in the annals of espionage by her Soviet code name, Sonia. It was an unprecedented honor for a woman who had already held two Orders of the Red Banner for her treacherous activities in several countries, especially in Great Britain, where she had been deeply involved in the theft of both British and American atomic bomb secrets during World War II. Shortly after she died, in Berlin in 2000 at the age of ninety-three, some of her other exploits were released from the Moscow archives for publication in Russian books. One of them, which had occurred in Oxford in 1943 under the noses of MI5, then located nearby, involved information so politically explosive that it was regarded by the British prime minister, Winston Churchill, as requiring the utmost secrecy. In August 1943, Churchill and President Franklin D. Roosevelt, accompanied by senior aides, met in Quebec to decide about the date and details of the invasion of Italy from North Africa and, later, of France from Great Britain. In addition, on August 19, they signed a separate agreement concerning collaboration between Britain and the United States on the production of an atomic bomb. The American atomic proj?ect was progressing so rapidly that Churchill wanted British scientists to join it there, but the U.S. government had objected to such a move. Previously, in June 1942, at a meeting in Washington, D.C., Churchill and Roosevelt had made a loose arrangement to pool atomic information and develop a bomb together, but with the setting up of the vast Manhattan Project, the United States was contributing so much more money and effort that the will to share the proceeds had seriously declined. At Quebec, Churchill was determined to exploit his friendship with Roosevelt to resurrect the partnership and enshrine it in a formal treaty. The old warrior’s persistence resulted in a separate two-page document, usually referred to as the Quebec Agreement. In it, the two leaders stated that Great Britain and the United S
