Crystal Night (The Prometheus Saga) by Charles A. Cornell
A short story set in the time of World War II and Nazi Germany.
A twist of alien science fiction. Who would think a bartender could be an alien? Johann is a probe sent here to observe the human species. The secrets some try to hide.
Well written and intense about a brutal time in history, especially for a short story. You will feel as if you are back in time in Germany.
