A good deal has already been heard, and written in the popular press, about Harold "Kim" Philby, the double agent who infiltrated the British Secret Ingelligence Service - and who at one stage was tipped to become its chief. E.H. Cookridge, an international authority on espionage, a former secret agent and author of several best-sellers including 'Inside SOE', knew Philby over a period of thirty-three years. In this book he provides the first complete dossier on Philby's fantastic double life.
