The Light Shines in Darkness -- the last of Tolstoy's plays, was left unfinished. In Russia it is prohibited on account of its allusions to the refusal of military service. Yet it is in some ways the most interesting of Tolstoy's posthumous works. It is obviously not strictly autobiographical, for Tolstoy was not assassinated as the hero of the piece is, nor was his daughter engaged to be married to a young prince who refused military service.
