Reymont: "Wampir"

Zenon is a man that awakes in London in a hotel 3 days after he receives a letter with an inexplicable message to follow, but not ask. He wanders around and cannot remember anything from the last 3 days, but meets up with a friend Daisy. She calms him, but later when he begins to follow her around and she doesn't seem to be herself. He follows her to an abandoned house and follows her into it and gets lost in the dark. His mind is filled with images of the unknown until he finds himself in front of Satan and he is conducting some rite. Daisy seems to be sacrificing herself for him and so she is devoured by her own panther. Zenon ends up outside and has a great feel for nature and starts hugging trees.
