“The King of Prague Bohemia”, who often shocked his contemporaries with the decadent and erotic motifs of his books, the troubadour of an old city that was disappearing before our eyes - Paul Leppin (1878–1945) belonged to the same galaxy of German-speaking writers as F. Kafka, who glorified Prague, G. Meyrink and M. Brod. Condensed to the utmost brevity, Leppin’s novel “Severin’s Walk into the Dark” is a story about dark passions, a web of phantasmagoria, the ghostly inhabitants of Prague and, above all, about this strange and fantastic city itself. For the first time in Russian - the key work of P. Leppin and the most important component of the “Prague text” as a whole.
