In particular, the study highlights fragments of his Samara activities (according to the letters of A.N. Neverov); introduces Dorokhov's drama "The Black Dragon" into scientific discourse and defines its semi - mystical role in the writer's fate; presents fragments of Dorokhov's interrogation in 1938 and the motives of the accusation - complicity in the Harbin terrorist organization; establishes the exact date of death, which until now, it has been recorded in a few essays about Dorokhov as incorrect; for the first time it gives a scientific analysis of the collection of Dorokhov's novels and short stories "The History of the city of Tarabarsk".
