In 1816, Mary Wollstonecraft Shelley and her husband Percy Bysshe
Shelley visited Lord Byron in Switzerland. After reading an anthology of
German ghost stories, Byron challenged the Shelleys and his personal
physician, John Polidori, to write horror stories of their own. Polidori
was the only one to complete a story, and a good one, at that. Mary did
come up with an idea though, and it became the germ of Frankenstein.
In The Vampyre, a handsome but naive young Englishman hooks up with
the strange Lord Ruthven to travel through Europe. As the young man gets
to know Ruthven, he discovers he is very generous to dissolute beggars,
but stingy to the worthy poor. He also likes to corrupt innocent women.
While the actual bloodsucking never gets exposed, this is a suspenseful
story with a satisfying ending.
