Scotland, the beginning of the 18th century. A dour young man dressed in black, raised to believe that he is one of God’s elect and can do no wrong, stalks his brother through the dusky streets of Edinburgh. Filled with hatred and self-righteousness, he feels that his religion justifies any number of crimes, including murder. The young man is accompanied by a powerful and mysterious companion who seems to change his appearance at will. In The Private Memoirs and Confessions of a Justified Sinner, evil at first triumphs over good, but ultimately unravels from the inside, lost in labyrinths of its own madness.
