I believe only in the teachings of Christ (...) I believe that our God Jesus Christ is love. I have no other God but him, wrote Dzerzhinsky: a Polish nobleman, a relative of Józef Pilsudski, a crystal-honest man, a loving father, a caring brother and a benefactor of orphans. The one who made a dizzying career in the service of the Bolshevik regime, who, with the help of the Cheka subordinate to him, exterminated hundreds of thousands of people and brought Joseph Stalin to power, only to later bitterly regret it. The first multifaceted and largely ambiguous biography of Iron Felix in free Poland. The book includes previously unpublished letters from Dzerzhinsky to his family and love confessions addressed to his mistresses - intercepted by the state security service and hidden for several decades in top secret Moscow archives to prevent a scandal.
