Before you is a sensational investigation conducted by the famous writer S.S. Mironin, author of the bestsellers "Stalin's Order," "Holodomor in Russia" and "The Case of Geneticists." A physician by training, doctor of medical sciences, the author analyzed the history of Stalin's last illness and related documents. For those who are engaged in the Stalinist period of history, it has long been no secret that Stalin did not die himself, but was killed. This, in particular, is reported by the former chairman of the KGB document declassification commission M. Poltoranin in his famous book "TNT Power." However, the history of Stalin's illness was classified for decades, and only now S. Mironin managed to get the most complete version of it.
