"Moonbeam Alley" (German: Die Mondscheingasse) is a short story by Austrian author Stefan Zweig, first published in 1922.
Walking in the streets of the small city at night, he hears a woman singing Weber's Der Freischütz.
Hearing his mother tongue in a French city attracts the young man and he follows the voice to find its source.
The young man is uncomfortable with the bar's sultry atmosphere and the lackadaisical, tired prostitute – he decides to leave.
This makes the narrator worry and since he is about to miss the night train, he leaves the bar and the alley mercurially.
