Still very much on a Gothic-decadent-romantic-horror tip, I'm really digging Arthur Machen right now. Just read The Great God Pan, a nice punchy novella laced with sexual obsession and cosmic fear, and am now on the much longer The Hill Of Dreams, which is more sedate and dwells mainly on lyrical beauty and themes of artistic angst and escapist nostalgia. Although to be honest, the main character is a sensitive-suffering-aesthete-adrift-in-a-world-of-uncouth-philistines to the point of being an insufferable pussyhole at times, to say nothing of a horrific snob. Still, it's gorgeously written.
Probably going to pick up Huysman's Against Nature next - got the complete Wilde sitting unread on my bookshelf, too...
