Crime and Punishment

This novel was conceived by Dostoevsky as a "psychological report on a crime," but in the process it transformed into a grand philosophical investigation about faith, conscience, responsibility for others, sin, and redemption.
"Am I a trembling creature or do I have the right?" - the question of the main character, addressed to himself and all of humanity.
And where is the limit of the permissible, beyond which there is no return from the "hideous dream" that has seized Raskolnikov's mind?
