The story of the murder of Grigory Rasputin - a Siberian "elder," a magician with a hypnotic look, an evil prophet, a savior (for some) and an enemy (for others) of Russia and the tsar - is well known to many. But this time the reader is invited to walk step by step with the heroes of the drama that took place on the December night of 1916 within the walls of the Yusupov Palace. At the same time, the author shows the general political background that reigned in and around the Russian Empire, as well as the atmosphere around the Romanovsky throne. Scrupulously examining every fact and every event, the author links them with the data of archival materials and the memories of eyewitnesses. As a result, the reader understands that he himself plunges headlong into a detective investigation, at the end of which the author independently goes to... the true killer of Grigory Rasputin. And this is the undoubted advantage of the new work of the famous writer-historian Viktor Senchi.
