 Bluebeard is a character in a story of the same name, written by Charles Perrault in the 1600s. Bluebeard is a wealthy nobleman who murders a succession of wives and hides their bodies in a locked chamber. He forbids his latest wife to enter this chamber, but one day when he is away she unlocks the room and discovers his grisly secret. Horrified, she locks the door and retreats, but she has got blood on the key and this gives away her deed to Bluebeard when he returns. The story ends happily when the wife is saved from Bluebeard by the entrance of her brothers, who slay the murderer.
