"A Devil Among People" (1991) is a dark, hopeless novella completed by Arkady Strugatsky less than half a year before his death, and first published under the pseudonym S. Yaroslavtsev, just like the story "The Details of Nikita Vorontsov’s Life" (1984). However, today both Boris Strugatsky himself and all his readers acknowledge that even things written by the brothers separately can and should be considered common, because they always and everything invented together.
