In the very heart of Prague, beneath the ancient house of Faust, shrouded in mysteries, a gloomy dungeon with amazing inhabitants and mysterious inscriptions on the walls is... suddenly discovered. Who will help to decipher them? Of course, Igor, Maxim, and Kira Knyazev. The curious, resourceful, and cheerful siblings are always ready for adventures—here they will find a hidden cache, there they will solve a puzzle, or decipher a message in a language unknown to science. And if one adventure leads to another, full of unknown dangers, the Knyazevs will be only happy. The more secrets and surprises, the merrier!
