Transport to another reality with the help of a book? Yes! Here is a story in which the heroes of the past live and act: the writer Gorky and the physicist Popov, Marshal Budyonny and Princess Diana, the creator of the great detective Conan Doyle and the aeronaut Kryakutny. Yes, it's confusing. For example, Alexey Maksimovich Gorky, no matter how unexpected it may sound, will take up investigations. And the inventor Popov will keep him company. Keep in mind: there is no hope for a quiet life in a stamp album. If you are a child, or at least a teenager, you are very lucky. If not, you will still have a fun time. Everything described above is in the adventure story “Marks” by Georgy Turyansky.
