'VENONA - The Greatest Secret of the Cold War' is the hitherto untold story of the peacetime equivalent of ULTRA, an extraordinary cryptographic effort conducted in conditions of unprecedented secrecy over three decades which gave Western counter-intelligence experts a fascinating glimpse into how Soviet Russia recruited and ran hundred of moles across the globe.
Based on the only complete set of decrypts held in Britain outside Whitehall, supplemented by interviews with most of the principal players in the VENONA drama, Nigel West identifies for the first time the real names of several important Soviet British speis and reveals that there are nearly 300 as yet unidentified former Soviet agents in America and Britain. The astonishing story of VENONA remains one of the last untold chapters in the history of the Cold War.
