Quando a polícia secreta soviética foi atrás dos espíritas

Soviet Seances: When The Chekists Came For The Spiritists, por Eduard Andryushchenko:

Aside from Lenin, the court heard from a number of early Soviet A-listers, some of whom might have cause to slander Stalin.

There was archrival Leon Trotsky, who was assassinated in Mexico City in 1940 on the Soviet leader's orders. And Nadezhda Alliluyeva, Stalin's second wife, who died under mysterious circumstances after a public argument with her husband in 1932.

Others speaking from the grave included the writers Maxim Gorky and Aleksandr Kuprin, as well as famed rocket scientist Konstantin Tsiolkovsky.

Their questioners were not members of the Bolshevik inner circle, but ordinary residents of the north-central Ukrainian town of Bila Tserkva who had never even belonged to the Communist Party.

For their role in conjuring up voices from the past, Ilya Gorban, his sister Vera Sorokina, and his lover Olga Rozova were arrested and accused of anti-Soviet acts and the "creation of an illegal religious-mystical group of spiritists."
