Civil war is the most terrible and cruel of all that humanity has come up with. All moral and ethical foundations are collapsing, fathers kill their own children, and some believers burn others right in churches. And everyone is looking for their own truth. The novel “Two Worlds” (1921) is the first large-scale work about the Civil War, which gained enormous popularity and was republished more than 10 times during the author’s lifetime! The merciless struggle between two worldviews gave rise to one of the most terrible repressive organizations in history - Cheka. Its employees, sincerely convinced of the rightness of their cause, of the greatness of the new, “proletarian” world, literally drowned Russia in blood, fighting for its bright future. And then they themselves, as unnecessary “slivers”, were thrown to the sidelines of history. The story “The Sliver” (1923), or “The Tale of Her and Her,” was the first truthful and terrible in its authenticity picture of the “class revolutionary struggle”, which showed its reverse side. The author of these outstanding works, Vladimir Yakovlevich Zubtsov (1895–1938), was shot. Rehabilitated posthumously.
