Address unknown is a short story by American author, Kathrine Kressmann Taylor. It consists of a series of letters between two friends over a period of sixteen months commencing in early 1932. After some years in America, Martin Schulse has returned to Munich with his wife Elsa and his five young sons, for the sake of their education. His good friend and business partner, Max Einstein runs their thriving art gallery in San Francisco, and sends financial reports along with personal notes. They touch on many matters including the political situation in Germany. The tenor of their letters quickly changes as Martin’s loyalties align with the new regime. His response when Max asks him to check on the welfare of Max’s younger sister, Grisella, an actress currently performing in Berlin, is disappointing, and elicits what at first seems a puzzling response. First published in 1938, this little piece still packs a punch today.
