I've always enjoyed Le Fanu's books despite his often musty style. Atmosphere, creepy characters, and weird comedy are his specialties. I wonder if Charles Addams read these books and was inspired to create his Addams Family cartoons?

I chose the current Penguin edition of Uncle Siles because of its excellent introduction and notes.
