Iris P., alias "Iris Schneider," was an undercover investigator who maintained close friendships and had intimate relationships with people she spied on.
For years, she investigated the left-wing scene and the "Rote Flora" in Hamburg until her exposure in the media in 2014. A few months later, two other undercover investigators in Hamburg were uncovered: Maria B. (cover name "Maria Block") and Astrid O. (alias Astrid Schütt).
