About the book (from Wikipedia):
Demons (Russian: Бесы, Bésy) is an 1872 anti-nihilistic novel by Fyodor Dostoyevsky. Although titled The Possessed in the initial English translation, Dostoyevsky scholars and later translations favour the titles The Devils or Demons.
Dostoyevsky’s most confused and violent novel, and his most satisfactorily “tragic” work, it began to appear in serial form in 1871, close after the publication of The Idiot, and only a few years after the publication of Crime and Punishment in 1867.
Inspired by the true story of a political murder that horried Russians in 1869, Fyodor Dostoevsky conceived of Demons as a “novel-pamphlet” in which he would say everything about the plague of materialist ideology that he saw infecting his native land. What emerged was a prophetic and ferociously funny masterpiece of ideology and murder in pre-revolutionary Russia.
