Call for the Dead is John le Carré's first novel, published in 1961. It introduces George Smiley, the most famous of le Carré's recurring characters, in a story about East German spies inside Great Britain. It also introduces a fictional version of British Intelligence, called "the Circus" because of its location in Cambridge Circus, that is apparently based on MI6 and that recurs throughout le Carré's spy novels. Call for the Dead was adapted for film as The Deadly Affair (1966).

David John Moore Cornwell, better known by his pen name John le Carré, was a British author, best known for his espionage novels, many of which were successfully adapted for film or television. A "sophisticated, morally ambiguous writer", he is considered one of the greatest novelists of the postwar era. During the 1950s and 1960s, he worked for both the Security Service (MI5) and the Secret Intelligence Service (MI6). Near the end of his life, due to his strong disapproval of Brexit, he took out Irish citizenship, which was possible due to his having an Irish grandparent.
