“Here God fights with the devil, and the battlefield is the hearts of people,” these words of Dostoevsky also relate to his own fate. It is no secret that in his personal life Fyodor Mikhailovich was neither an angel nor a monk, and his secret passions often developed into vices and obsessions. Gambling addiction and eroticism, obsession with roulette and femme fatales, heightened sensuality reaching the point of voluptuousness, painful love-hate on the verge of self-torture - all this spilled out onto the pages of his great novels. What allowed him not only to explore the perverted consciousness of murderers, maniacs, terrorists, but to literally turn them inside out, describing with stunning authenticity these demons in human form, all these Verkhoven and stinkers? Is it true that in this way he sublimated his own painful fantasies and sinful urges? What role did the severe mental trauma inflicted by the death sentence, which was canceled literally at the last minute, already on the scaffold, and many years of hard labor play in his work and intimate life? And weren’t his “madnesses of passion” and “shameful desires” clinical symptoms?.. This shocking book allows you to look into the most distant, dark and forbidden corners of the soul of a brilliant writer, for the first time shedding light on his secret passions and vices, with which demons and with demons he had to fight, what fierce battles between God and the devil raged in his great heart.
