The Were-Owl of China

In the mid 1700's, babies were dying in what is now Beijing China. Wherever they struggled for life, an owl was always observed nearby. Hearing of the owl, an archer waited in the room where yet another baby was dying. Once spotted, he shot the owl which left a trail of blood while escaping. Following the trail the archer discovered a servant girl who was incapacitated by a wound to her loin. She admitted leaving her room at night to feed on the babies brains. She was burned alive and the epidemic came to a close.
