On December 1, 1934, exactly 90 years ago, "the boy from Urzhum", aka "the party's favorite" Sergei Mironovich Kostrikov (party nickname Kirov) caught a revolver bullet in the corridor of the Smolny Palace, albeit fired by an unemployed communist, Lenya Nikolaev. The mentally unstable Nikolaev was ideal for the role of a killer. And they probably used him "in the dark". Someone told him that his wife was having an affair with Kirov. Someone let him into Smolny with a revolver, despite his long-expired pass. Moreover, he went not through the general entrance, but through a separate entrance used by Kirov and other high-ranking party officials.
