About the book: 2019 / This unique book is both an interesting collection of detective stories describing real events and people who really existed, and the most objective and plausible evidence about pre-revolutionary Russia, since it was written by a responsible person of the tsarist regime, but with great sympathy and understanding it shows the most vile sides of that society. Moreover, these are the memoirs of an amazing man who abandoned the officer life of a wealthy nobleman and, in response to his calling, became the best Russian detective, nicknamed the “Russian Sherlock Holmes.” He turned the Moscow police, which he headed in 1906 and found in a disgusting state, into the best in the world, as criminologists in Geneva recognized in 1913. Here another very important page of pre-revolutionary Russia is revealed: the Beilis case, which is now forgotten, but played a big role in the history of the revolution of 1917. The book is easy to read, like a detective story, because it is several detective stories under one cover, and like a historical novel, because this is historical evidence. The publishing design is preserved in PDF A4 format.
