If you're already familiar with Dr. Proctor, then you know that don't feed him bread, just let him invent something crazy (in a good way). If you're already familiar with Lise, then you know that she has very few friends. To be honest, she has only one friend - Bulle from the house opposite. If you are already familiar with Bulle, then you know that he is the smallest, red-haired, fastest and most cheerful boy in the universe. Oh yes, even the most freckled one! And if you don’t know them, then that’s okay, it’s not too late to get to know them now, when the whole trio is about to get caught up in history. More precisely, into History. And you won’t get stuck, but will plunge, because that’s how Dr. Proctor’s time machine works. At the same time, you will have a rare opportunity to find out why Napoleon actually lost the Battle of Waterloo, for which they actually wanted to execute Joan of Arc and where the idea of the Eiffel Tower in Paris actually came from. Hold on tight, the dizzying race through time begins! For the first time in Russian!
