Spying, as well as other intelligence assessment, has existed since ancient history. In the 1980s scholars characterized foreign intelligence as "the missing dimension" of historical scholarship."[1] Since then a largely popular and scholarly literature has emerged.[2] Special attention has been paid to World War II,[3] as well as the Cold War era (1947–1989) that was a favorite for novelists and filmmakers.[4]
