It so happened that the best books about captivity in Russian literature were created by former “inmates” - Fyodor Dostoevsky, Alexander Solzhenitsyn, Varlam Shalamov. Former “jailers,” alas, do not write memoirs. In this sense, the works of the Russian prose writer Alexander Filippov are a rare exception. The author served in correctional institutions for many years in various positions. That is why Alexander Filippov’s books are distinguished by authenticity, knowledge of the material and undoubted literary talent.
