Rein wrote literary criticism that was published in 1947/48 in the
Socialist Unity Party of Germany (GDR) magazine
Einheit - Theoretical Monthly Journal for Socialism. In addition, Rein wrote novels and short stories, reflecting contemporary history. In 1949, he published the anthology
Unterm Notdach,
Berlin Tales. In 1950, according to preliminary remarks on behalf of the chairman of the Cultural Advisory Board,
Erich Weinert, an attempt was made to survey the narrative prose that appeared in Germany after the war and was published under the title
The New Literature. In addition to his own contributions, the work contains two reviews of
Berlin Finale, by
Hans Mayer (pp. 315–319) and by
Walter A. Berendsohn (pp. 319–324). Initiated by
Johannes R. Becher, a campaign was launched against the new literature in GDR magazines, which led to the publisher taking the book off the market and Rein's membership of the Cultural Advisory Board was suspended. He then lived as a freelance writer in the GDR. After breaking with the GDR in the early 1950s, he moved to West Germany. There he lived in
Baden-Baden until his death. His books on the end of the war and the immediate postwar period in Berlin, made him an East German representative of rubble literature (
Trümmerliteratur). In the GDR, some of his books were printed with difficulty and with a delay. After moving to the West, he wrote mainly short stories, but also satires and cabaret texts.
Fritz J. Raddatz wrote an afterword for the new edition of
Berlin Finale in 2015. and was one of the first German bestsellers of the postwar period. The novel has been translated into English three times. In 1952, it was published by MW Books as
Finale Berlin in an abridged translation by David Porter, representing about one-third of the German text. In 2015, it was published by Schöffling & Co. as
Berlin Finale in a translation by Geoff Wilkes. In 2019, it was published in the Penguin Modern Classics series as
Berlin Finale, in a translation by Shaun Whiteside. ==Works==
