James Hogg 
The Private Memoirs and Confessions of a Justified Sinner [EPUB ebook] 

The plot concerns Robert Wringhim, a staunch Calvinist who believes he is guaranteed Salvation and justified in killing those he believes are already damned by God. The novel has been classified among many genres, including gothic novel, psychological mystery, metafiction, satire and study of totalitarian thought, it can also be thought of as an early example of modern crime fiction in which the story is told, for the most part, from the point of view of its criminal anti-hero. The action of the novel is located in a historically definable Scotland with accurately observed settings, and simultaneously implies a pseudo-Christian world of angels, devils, and demonic possession.
