Victor Sencha – writer, publicist; by training a military doctor-expert and lawyer. In his book “Dantes’ Button” he explores the reasons for the death of the great Russian poet. And not only. With the death of Pushkin, his duel will not end - it will continue within the framework of the criminal trial of a military court, during the sessions of which the killer will defend his blood-stained honor. For a long time, the so-called “Genuine military court case of 1837” on the fact of Pushkin’s duel with Dantes was classified. What was hidden behind the secret seals is up to the reader to find out. The button of Dantes’ killer itself – as an object – is by no means the author’s invention. It is found in the memories of witnesses, becoming over time a legendary mystery object around which thousands of research copies have been broken. And the reason for this was her secret, which the author managed to reveal on the pages of his book. Like many other secrets associated with the name of the genius of Russian literature A.S. Pushkin.
