The Idiot by Fyodor Dostoyevsky

THE IDIOT follows the life of young Russian Prince Lev Nikolayevich Myshkin, who returns to Russia after spending several years at a Swiss sanatorium. An outcast from the high society of St. Petersburg for his trusting nature and naivete, Lev finds himself at the center of a love triangle between a beautiful kept woman and a virtuous and pretty young girl, both of whom win his affection. Unfortunately, Lev's very goodness precipitates disaster, leaving the impression that, in a world obsessed with money, power, and sexual conquest, a sanatorium may be the only place for a saint.
