SNOW is the codename assigned to Arthur Owens, one of the most remarkable British spies of the Second World War. This typical Welsh underfed type became the first of the great double-cross agents who were to play a major part in Britain's victory over the Germans. When the stakes could not have been higher, MI5 sought to build a double-cross system based on the shifting loyalties of a duplicitous, philandering, and vain anti-hero who was boastful and brave, reckless and calculating, ruthlessand mercenary . . . but patriotic. Or was he? Based on recently declassified files and meticulous research,Snow reveals for the first time the truth about an extraordinary man.
