Set in a fictional town in northern Russia, where highly classified research in magic occurs, the novel is a satire of Soviet scientific research institutes, complete with an inept administration, a dishonest, show-horse professor, and numerous equipment failures. It offers an idealistic view of the scientific work ethic, as reflected in the title which suggests that the scientists' weekends are nonexistent. (Wikipedia)
