Don's finale read: The Spy Who Came in from the Cold
Le Carré's 1963 novel follows Alec Leamas, a worn-out British agent sent on one last job against East Germany. Graham Greene called it the best spy story he had ever read. Le Carré was a working MI6 officer when he wrote it, so he was also using a fake name at the office.
