Greetings!
I came across "The Last Lords of Gardonal", by William Gilbert (1867) in an anthology of vampire stories I checked out of the library. I enjoyed this story so much that I read it out loud later that same night for my husband and daughter.
Actually I could see this story being adapted wonderfully for the screen.
The overall theme of the story has to do with a very evil and powerful man being completely bested in a very creative way. I noticed it isn't in the Librivox catalog, but it is in the public domain:
