Agoniia SSSR. Ia byl svidetelem ubiistva Sverkhderzhavy - Zen'kovich Nikolai

Putin called the collapse of the Soviet Union a "great geopolitical catastrophe," saying that the Soviet Union was also the greatest crime of the 20th century.
Author of this book observed the tragedy of 1991 not from the outside, but from the inside - being an employee of the Central Committee of the Communist Party, he personally attended the meetings of the highest bodies of the party power and became the "internal chronicler" of the agony of the USSR.

Why was not heard the warning of Y.V. Andropov, who wrote 10 years before the "perestroika" that the CIA was recruiting "agents of influence" in the USSR to "decomposition of Soviet society" and the collapse of the country?
Is true that Gorbachev was involved in the putsch of the SCCP and whether it is worth believing the words of Yanayev: "Gorbachev is aware of the events. He'll join us later"?
Will the mystery of the "strange series of suicides" be solved - Marshal Akhromeev, "chief treasurer of the party" Kruchina, Pugo, Pavlov, Lisovolik?
Why, after reading these notes, the author was advised: "What floor do you live on? On the sixth? We need to move lower urgently. Or you can accidentally fall out of the window..."
