The silent girl is an allegory and direct reference to the German right-wing extremist and member of the NSU terrorist group: Beate Zschäpe. The National Socialist Underground (NSU) was a right-wing extremist and right-wing terrorist group that existed between 1998 and 2011. Between 2000 and 2007, the NSU systematically murdered ten entrepreneurs living in Germany - mainly with Greek and Turkish immigrant backgrounds.
