There is a gently comic moment in John le Carré’s The Spy Who Came in From the Cold in which the novel’s jaded, cynical protagonist, a British intelligence agent named Alec Leamas, quizzes Liz Gold, the young librarian who is about to become his lover, about her beliefs. He asks her if she is religious, and Gold replies that she doesn’t believe in God. “Then what do you believe in?” Leamas presses. “History,” she answers. “Oh, Liz…oh no,” Leamas exclaims. “You’re not a bloody Communist?” She nods, blushing.
