Arrested, interrogated and watched: Ulrike Poppe was a dissident in the former GDR and spent 15 years being spied on by the East German secret police - the Stasi- who installed secret microphones in her home and cameras pointing through the windows. Then, in 1992, after Berlin Wall came down, she was granted access to the Stasi archives and discovered 20,000 pages of details about her life with the names of friends and colleagues who'd informed on her. In those pages she also found the name of the Stasi officer in charge of her case and decided to track him down and confront him.
