Golden flows the steel - Wolokolamsker Chaussee

Karl Grünberg was a German communist writer and journalist. His play "Golden fließt der Stahl", which premiered in 1950 at the Stadttheater Nordhausen and was particularly succsessful, works dramarturgically as a combination mystery thriller and socialist propaganda piece. At an important steel factory in the rebuilding GDR of 1949, an engeneer has disappeard, and his wife insists he did not defect to the West but rather was murdered; while solving the crime, she also discovers a saboteur, who is rehabilitated into society at the end of the play.
