Venedikt Erofeev (1938-1990) became famous primarily as the author of the poem "Moscow-Petushki" (1970) and the play "Walpurgis Night" (1985). However, in each interview, the writer mentioned his first major work - "Notes of a Psychopath" (1957), emphasizing that he would not refuse to publish it now. In 2000, the work was published, but was reduced three times and subsequently reprinted in the same stripped-down form. For the first time in the world, it presents a complete version of "Notes of a Psychopath," painstakingly verified according to the author's manuscript and freed from numerous mistakes and omissions made in previous publications.
