While the Cold War (World War 2 as well) provided a rich fodder of material for espionage novelists, almost all novels I've come across of this genre have been British & American. I'm sure the Soviet Union had its own spy novelists, but I've not encountered any, not even English translations. I'm surprised to have not seen any German spy novel; the partition of Germany during the Cold War should've provided plenty of incidents for German spy novelists.
Could somebody suggest some good examples of non-British & American spy fiction? Language, country & era no bar.
