This book is a new work by the famous historian and researcher Yu.A. Zhuk, which will tell about the life path of the regicide P.Z. Ermakov, and will also tell the reader the history of his personal weapon - the Mauser K-97/12 pistol No. 161474, which for many years was considered the “weapon of execution of Nikolai Romanov.” A special place in the book is occupied by the memoirs of P.Z. Ermakov about the “Tobolsk epic of the Romanovs”, as well as about the murder of the “former tsar and his family”, equipped with extensive author’s comments. All sorts of rumors have been circulating around the name of Ermakov - a man of a very low intellectual level, but desperately brave and pathologically cruel - to this day. The author will reveal many secrets associated with one of the murderers of the Royal Family.
