Crime and Punishment is the story of a murder committed on principle, of a killer who wishes by his action to set himself outside and above society. A novel of great physical and psychological tension, pervaded by Dostoevsky's sinister evocation of St Petersburg, it also has moments of wild humour. Dostoevsky's own harrowing experiences mark the novel. He had himself undergone interrogation and trial, and was condemned to death, a sentence commuted at the last moment to penal servitude. In prison he was particularly impressed by one hardened murderer who seemed to have attained a spiritual equilibrium beyond good and evil: yet witnessing the misery of other convicts also engendered in Dostoevsky a belief in the Christian idea of salvation through suffering.
