This work provides an opportunity to get acquainted with the history of the criminal world, the theory of theft, deception, fraud, and learn about the life of “dashing people.” The author does not limit himself to a simple description of facts and events; each chapter of “KVEN” is a unique philosophical treatise, in which there is a place for the harsh truth of life, history, and humor. The materials presented in the book are exceptional; familiarizing yourself with them is not only useful, but also extremely interesting. Some chapters may seem too “hard”, but all the stories are genuine, and to ignore them is to ignore the opportunity to make our lives better, cleaner, more honest. Usually the instructions describe in detail how and what needs to be done; this “instruction for a quiet life” also answers the questions “why?” and “why?” The book is addressed to a wide range of readers.
