Maurice Castle Nicol Williamson is a midlevel bureaucrat in MI6 whose life seems completely without peculiarity, peccadillo, or any highlighting quality to suggest hes anything but a dull bureaucrat, except for the interesting, casually introduced detail that he has an African wife, Sarah Iman, and son, Sam Gary Forbes. Meanwhile, the company regime, represented by corpulent, bluffly cheery Dr. Percival Robert Morley, whos actually an expert in assassinations and biological toxins, and grey eminence Sir John Hargreaves Richard Vernon, advise newly appointed security chieftain Daintry Richard Attenborough that, thanks to a source they have cultivated in their Moscow enemy headquarters, they believe they have a traitor at the MI6 African desk. The duo determine that the mole must be quietly killed, rather than be allowed publicity in a trial or a flight to Moscow. They determine quickly that the most likely candidate for the traitor is Arthur Davis Derek Jacobi, Castles playboy office partner. Actually, Castle is the mole, but the information he leaks is entirely unimportant financial documents. He became involved in leaking to the Soviets when he was an MI6 agent in South Africa, seven years earlier he met and fell in love with Sarah, and when their affair was discovered by the authorities, Castle was all but thrown out of the country, and he entrusted Sarahs smuggling out of the country to a mutual communist acquaintance. Ever since, hes been repaying the favor by filtering insignificant data to the Soviets. Castle makes one last informational drop to his communist handlers and he is summarily whisked off to Moscow for protection. However, Castles primary problem is that he is not a communist, is not a communist sympathizer, and has absolutely no interest in politics, socialism, the Russian language, Slavic history or culture, geopolitical power plays, Moscow nor the Soviet Union. His only interest is in his wife and his son, who are left in London where they will
