Mysterious disappearances of ships and extraordinary, now forgotten inventions, secrets of ancient tombs and attempts to decipher signals from space - history has preserved a lot of strange, exciting imagination. The magazine from issue to issue publishes materials about this under the heading "Anthology of mysterious cases." The most interesting of them are included in the collection. It is this moment that excites the most. Why will readers open the magazine, which they see for the first time and the pages of which are known to me in all details - after all, for me this issue, on which the editors have been working hard for several months, is a past phenomenon.
