The Tragical History of Doctor Faustus by Christopher Marlowe - Haven't read it but I definitely want to... I have both volumes of HORROR 100 BEST BOOKS and the chapter on this made me want to read it.

The Monk by Matthew Gregory Lewis  - read it and bought a nice copy, too. It's one of the more enjoyable gothics to me... it translates to the modern reader very well, which is important. The Monk himself is actually a sort of child prodigy as far as religion goes... he's never been exposed to an impure thought, and he's had the best Classical education, enabling him to give marvelous sermons. When he finds out that one of the members of his order is not who he claims to be, his entire existence comes crashing down. I can't give away more than that without robbing the ending of its zing, but it's a cracking good read.

Frankenstein by Mary Wollstonecraft Shelley - the most imporant thing for a new reader to realize is it's nothing like the Universal movies. The Arctic bookends are a slog to get through, but the actual story has flashes of Gothic brilliance here and there. The fictional device of the Creature learning to speak and read by eavesdropping on a child's tutoring is kind of a reach, but it does enable the thing to converse with its creator like a son to the manor born.

Melmoth the Wanderer by Charles Maturin - I'm reading this now, and it's well written and has some great little Gothic (I'm using the word deliberately in this whole post to delineate a certain style and flavor) flourishes. But I'm still near the beginning. The actual plot is highly convoluted so far... flashbacks inside of flashbacks, etc.

The Wandering Jew by Eug - I'm interested in hearing about this one...

Uncle Silas
by J. Sheridan Le Fanu  - bought this a few months ago but haven't had a chance to read it yet.

Dr. Jekyll and Mr. Hyde by Robert Louis Stevenson - great little novel, but again nothing like most movies. One thing I liked was that Stevenson's Hyde was a malformed dwarf... not the Hulk of movies like VAN HELSING. A subtle approach to depicting the true nature of evil.

The King in Yellow by Robert W. Chambers  - I don't know if you're referring to the book or just to the short story, but I've read about half of the KIY... the genre fiction of it, at least. "The Repairer of Reputations" was an interesting near-future story that managed to predict WWI years ahead of time. It's just weird enough that I find it remarkable that Chambers wrote it... he apparently wrote a lot of romance and disposable fiction that was "of its time" and nothing more... He was very successful at it, but it's amazing that he came out with The King In Yellow, because a couple of stories in it are just so weird. The title story is positively pre-Lovecraftian. Also, the KIY (the book within the story) is notable as an early example of an evil fictional tome, which Lovecraft would later put to much use. Definitely recommended

The Island of Dr. Moreau by H. G. Wells - I loved this book. It's a great riff on the Frankenstein story. While the movies just tended to deal with the immediate horror of the situation, the book lingers on after Moreau's death, and we see the animal-men descend back into animals over a length of time. Great stuff, although the vivisectionalist approach was sort of ridiculous. (The Kilmer/Brando movie's DNA splicing was much better, whatever you thought of the movie itself.)

Dracula
by Bram Stoker - I've read the book a few times, and enjoyed it... but not recently. I have the annotated version but haven't read it yet. Lair of the White Worm is wilder, but there's no denying this one is the better of Stoker's novels. It started an avalanche of vampire/Dracula knockoffs, after all. It's a novel of letters, corresondence and diary entries, though, so if you don't like that gimmick you may not appreciate the fact that Dracula is almost always a distant character from the others' points of view (Mina, Harker, etc.). It's very Victorian, which means it ladles on the blood and sex while shuddering about it.

The Picture of Dorian Gray by Oscar Wilde - I love the book, although over a hundred years later, Dorian Gray's crimes now seem quaint. Drug abuse? The love that dare not speak its name? A hundred years of 20th century horrors hasn't made Dorian Gray seem quite the monster he used to be. Still, this is definitely one of the classics, and much better written, I dare say, than some. The book is full of the bitchy, catty, snide little asides Wilde was famous for, mostly from the dandy Lord who watches Dorian's descent from start to finish. And it's very sensuous in terms of fashion, design, and aromas. The best of the Decadent novels, perhaps.

I'd love to read all the books on this list, but it will probably be a few years before that happens!

A perfect Monster has no end...
