So many good series made involving the subject though. Both drama and documentary. I mean, you do want drama and not documentary? Cause the story The Americans is inspired by is documented.
For drama, check Deutschland '83 and the two successors. Has a great cast.
And of course there is Clifford Stoll's book about how he caught Hagbard Celine (see the movie '23' with a young August Diehl who later broke through in Hollywood).
German cinema, both West-German and modern, has gems regardless (I am not German btw, subs are easy to come by).
