About the book: 2006 / The book of the writer and literary critic Viktor Kuznetsov “The Mystery of Yesenin’s Death” (M., Sovremennik, 1998) aroused great interest in Russia and abroad. The study for the first time used recently secret archival and documentary sources from hard-to-reach funds (VChK-GPU-NKVD, Ministry of Internal Affairs, etc.). In his significantly expanded and revised book, V. I. Kuznetsov presents new facts and arguments that convincingly prove the murder of the great Russian poet. The main text of the work is accompanied by memoirs and materials from contemporaries, complementing his biographical portrait. For the first time, the book provides references to unknown and rare archival data. The study is illustrated with unique photographs and documents.
