The collection "The Hunt for Setavr," which is offered to readers by the Mir publishing house, presents completely different at first glance diametrically opposite lines of Lem's work. Most of the collection is occupied by stories about the space pilot Pirx, which make up the cycle. The first stories of this cycle were written seven years ago (they were included in the collection "Invasion from Aldebaran"), the last - "The Hunt for Setavr" - was completed in December 1964.
