KARLA

Karla

Karla is a fictional character in several novels by John le Carré. A Soviet Intelligence officer, he most often appears as a distant antagonist of George Smiley. His real name is never revealed; instead he takes his codename from that of the first network he recruited. His most prominent appearances are in Tinker, Tailor, Soldier, Spy; The Honourable Schoolboy; and Smiley's People, three novels which were later published as a single omnibus edition entitled Smiley Versus Karla or The Quest for Karla in the US.
