The Human Factor

'The Human Factor' marks Graham Greene's triumphant return to the ambiguous world of deceit, illusion, treachery, faith and loneliness that is espionage, a world that has always fascinated Greene and was the subject of one of his most famous novels. The central figure of 'The Human Factor' is Castle, and old member of 'the firm,' now efficiently (if ungloriously) processing intelligence from England's former African colonies. . .there is more to Castle than meets the eye.
