Subsequently, Zinoviev often returned to this story, including in his memoirs "The Confession of the Outcast", calling that year the "year of horror". This episode of the biography is in general terms mentioned in encyclopedic publications, its credibility is generally not questioned by biographers and commentators. Pavel Fokin pointed out that the arrest and search documents were not kept, therefore it is difficult to establish the exact chronology of events. Konstantin Krylov noted that sincerity and lack of heroism in the descriptions of events testify in favor of their authenticity. A Swiss literary critic Georges Niva believed that Zinoviev later constructed his biography around the complex of a terrorist whose rebellion remained imaginary. As a result, his whole life became a fierce resistance to the course of history, in this context it does not matter whether the murder of Stalin was planned in reality.
