The Idiot by Fyodor Dostoyevsky

Returning to Russia from a sanitarium in Switzerland, the Christ-like epileptic Prince Myshkin finds himself enmeshed in a tangle of love, torn between two women—the notorious kept woman Nastasya and the pure Aglaia—both involved, in turn, with the corrupt, money-hungry Ganya. In the end, Myshkin’s honesty, goodness, and integrity are shown to be unequal to the moral emptiness of those around him.
