the crowds who pass him in the street without a glance; he clings to them for his anonymity and his safety. His fear makes him servile—he could embrace the shoppers who jostle him in their impatience and force him from the pavement. He could adore the officials, the police, the bus conductors, for the terse indifference of their attitudes.But this fear, this servility, this dependence had developed in Smiley a perception for the colour of human beings: a swift, feminine sensitivity to their characters and motives. He knew mankind as a huntsman knows his cover, as a fox the woods. For a spy must hunt while he is hunted, and the crowd is his estate. He could collect their gestures, record the interplay of glance and movement, as a huntsman can record the twisted bracken and broken twig, or as a fox detects the signs of danger". Like Le Carré, former British Intelligence officer Graham Greene also examined the morality of espionage in left-wing, anti-imperialist novels such as The Heart of the Matter (1948), set in Sierra Leone, the seriocomic Our Man in Havana (1959) occurring in Cuba under the regime of dictator Fulgencio Batista before his deposition in the Cuban Revolution (1953–59), and The Human Factor (1978) about a MI6 agent's attempts to uncover a mole in apartheid-era South Africa. Greene had worked as a MI6 agent in Freetown, an important British naval base during World War Two, searching for German spies who would radio information about the movements of ships to the Kriegsmarine, experiences which inspired The Heart of the Matter. Greene's case officer during World War Two was Harold "Kim" Philby, who was later revealed in 1963 to be a long time Soviet spy, who had been recruited by Soviet intelligence in the early 1930s while he was an undergraduate at Cambridge. Greene's best known spy novel The Quiet American (1955), set in 1952 Vietnam featured a thinly disguised version of the real American intelligence officer, Major General Edward Lansdale as the villain. Greene had covered the Vietnam war in 1951-52 as a newspaper correspondent where he met Lansdale who appears in The Quiet American as Alden Pyle while the character of Thomas Fowler, a cynical, but goodhearted British journalist in Saigon was partly based on himself. MI6 was outraged by Our Man In Havana with its story of James Wormold, a British vacuum cleaner salesman in
