Asterisk denotes entries on real places.
*London.
London itself is not free of racial prejudice. Castle mistakenly believes that no one in London would mind the “African blood” of his wife. However, a passerby addresses her with the derogatory term “Topsy”–echoing a nickname for a black slave girl in Harriet Beecher Stowe’s novel Uncle Tom’s Cabin (1851-1852). Greene ridicules London’s class-conscious society through Sir Hargreaves’s marriage to an American woman who brought him wealth, status, and a promotion in the London office at a time when he was an inexperienced man in the firm.
*South Africa. Homeland of Castle’s wife, Sarah. Castle’s flashbacks to his years in South Africa reveal a setting during the period when apartheid was supreme. At the same time, political rivalries among Western countries led to partnerships with South Africa’s government that promoted economic imperialism that helped to perpetuate the apartheid system. The United States, Great Britain, and South Africa are collaborating in covert activities in support of Uncle Remus Operation as a joint endeavor, sharing of secret information on diverse issues, such as guerrillas, blockades, Cuban or Russian penetration, or economic interests.
While living in South Africa, Castle had to break the country’s rigid racial-separation laws in order to be with Sarah. This experience opened his eyes to the evils of apartheid and made him sympathetic to the plight of black South Africans. In fact, he became a Soviet informant because of his sympathy for Africans.
*Moscow. Capital of the Soviet Union. When Castle fears that he will be discovered as a double-agent, the KGB arranges his escape from England to provide him sanctuary in Moscow. There, he discovers that he must learn a great deal about Russian culture and language. At the same time, he learns that the Russians have merely used the information Castle has sent them to make Western nations believe there is a double-agent in Moscow who does not actually exist. This disclosure comes to Castle only after he is virtually a prisoner in Moscow. Meanwhile, England turns into a prison for Castle’s family because his wife does not have her son on her passport. There is an irony of fate in the separation of this family that had come together across continents; in the end, Sarah and her son are forced to remain in England, while Castle leads a life of an exile in Russia.
