The book is an action-packed story by E. Kestner “Emil and the Detectives,” adapted (without simplifying the original text) according to the method of Ilya Frank. The uniqueness of the method lies in the fact that memorization of words and expressions occurs due to their repetition, without memorization and the need to use a dictionary. The manual promotes effective language acquisition and can serve as a supplement to grammar textbooks or to basic classes. Intended for students of German studies, for those studying German on their own, as well as for everyone interested in German culture. The story of teenagers tracking down a criminal is one of the most famous works of German children's literature of the 20th century. A children's thriller, so to speak.
