During the 1960s and '70s, David Cornwell worked as a member of British intelligence while secretly publishing spy novels under the pen name John le Carré. By his third novel, le Carré had become an international success. He quit his job in order to focus on writing full time. He is a force in the world of spy fiction and many of his novels are considered to be some of the best of the genre. His recurring character George Smiley features in many of his Cold War era novels and is considered to be one of literature's greatest spies. Le Carré has continued writing into his eighties, with his most recent novel A Legacy of Spies published in mid August of this year. Readers new to le Carré should look to the following examples of his impressive body of work.
