Fyodor Dostoevsky – Demons (aka The Possessed)

Everything’s more or less normal in the little town of N until Piotr Stepanovich and his equally psychopathic sidekick, Nikolai Stavrogin, come back from abroad. One thing leads to another leads to another and another and some more after that in Dostoevsky’s extraordinarily rambling (as rambling as this sentence) novel, which does not end well for anyone involved, reader included. The devil inside, the devil inside, every single hour of reading this book – the devil inside.
