For readers of Legacy of Ashes comes an extraordinary and immensely readable account of six disastrous decades of Soviet espionage—from noted intelligence authority Chapman PincherThis landmark book is a massive, meticulous, and utterly riveting account of the duplicity and incompetence that characterized twentieth-century Soviet espionage and the British response to it.Using a huge cache of recently released documents and exclusive interviews, Chapman Pincher makes a compelling new case that—as he has long believed—the head of Britain’s own MI5, Roger Hollis, was a double agent acting to undermine and imperil the United Kingdom and America. Here too, Pincher provides an exciting new perspective on the most famous operatives of our time, from Kim Philby to Klaus Fuchs, and recounts suspect incidences of dark happenstance and coincidence, such as the infamous “Profumo Affair” sex scandal.Written with the power of a heart-pounding thriller, Treachery is a warning about protecting our societies and institutions from enemy infiltration, and is bound to become a much-cited source now that Russia is dangerously flexing its military—and espionage—muscles once again.
