Bluebeard is a heinous and clearly misogynistic character who has a “murder room” in his house for killing his wives, of which it seems there were many. When he is called away for a trip he gives his current wife (who married him despite how ugly his blue beard makes him) keys to all of the rooms of his estate with the warning that she is not to open one of the rooms - the murder room. She does anyway (come on, wouldn’t you?), and when he finds out he threatens to kill her too. Fear not! Bluebeard gets what he deserves in the end and is killed by his wife’s brothers. His widow then uses his great fortune to take care of her family and buy herself a more reasonable (and presumably less murder-y) husband.
