The author of this book, a young historian and writer, reveals the scandalous secrets of the “Kremlin Central” (as the toughest prison in Russia, 99/1, was nicknamed), where Ivan Mironov was imprisoned on charges of assassinating Chubais. The heroes of “Immured” are persons involved in the most high-profile criminal cases: “YUKOS”, “MMM”, “Three Whales”, “Social Initiative”, “Arbat-Prestige”, murders of Otari Kvantrishvili, editor-in-chief of the Russian version of Forbes Paul Klebnikov, first deputy chairman of the Central Bank Andrei Kozlov... Ivan’s cellmates Mironov included the “night governor of St. Petersburg” V. Barsukov (Kumarin), and the legendary killer A. Sherstobitov (Lesha Soldat), and the “resurrectionist” G. Grabovoy, and the bloodiest skinheads. Confessions without cuts, prison interviews without fear and censorship. The background of the resonant processes of the last decade is revealed from the first persons.
