The Human Factor
Graham Greene's 1978 novel is a spy story that cares less about tradecraft than about the private weaknesses that make treason possible. Maurice Castle, a middle-aged MI6 officer, leaks secrets not from ideology but from love, or from the habit of protecting someone he has convinced himself needs protection. Greene treats the betrayal as a domestic failure that happens to have geopolitical consequences.Avon's edition presents the novel in a mass-market paperback format, the kind that turned up in drugstores and airports during the late Cold War. It is a reading copy of a novel that understands espionage is mostly a matter of character, and it is for readers who know that the most dangerous secrets are usually kept from oneself.
