Blue Beard

I read "Blue Beard".

There was a man who was really really rich but he had ugly blue Beard. And there was bud rumor of him. One day, he said to a woman who have two daughters that he wanted to marry one of her daughters. After all, the youngest sister married him.
About a month afterward　he had to leave home. So, he explained that keys of his house to his wife. Finally, he especially forbade to use the little key of the closet. Wife said OK then, but after Blue Beard went out, she couldn't overcome her strong curiosity. She used the little key and open the door. 

This story was little scary for me.
