In this book, Conan Doyle is the author of several unusual plots for the reader. In the first part, he deeply analyzes the works of the most talented writers, from his point of view, as if opening a “magic door” and drawing him into their creative laboratory. In the second part of the book, the reader finds himself in a mystical world, presented, however, so vividly and realistically that it feels as if the amazing events described are happening in reality.
