In James Hogg 1824 novel Confessions of a Justified Sinner, a young man named Robert Wringhim, or sometimes Wringham, encounters a shape-shifting devil. Robert is told that he is one of a small group of people predestined for salvation, and this doppelganger demon convinces him to commit murder and other crimes. Part Gothic novel, part case study in psychology, this is a probing quest into a world of angels and demons, predestiny and fanaticism.
