Decadence and dread: three novels of the fin de siècle

We focus on three novels which reflect the dark and dangerous ideas of the fin de siècle: Bram Stoker's Dracula, Oscar Wilde's The Picture of Dorian Gray and Robert Louis Stevenson's Dr Jekyll and Mr Hyde. How does each novel deal with late-Victorian anxieties about race and class, post-Darwinian fears of 'degeneration' of the species, and the illicit pleasures of breaking with social, sexual and moral convention?
