After having somewhat recovered from the shock, she picked up the key,
locked the door, and went upstairs into her chamber to compose herself;
but she could not rest, so much was she frightened.

Having observed that the key of the closet was stained, she tried two or
three times to wipe off the stain, but the stain would not come out. In
vain did she wash it, and even rub it with soap and sand. The stain
still remained, for the key was a magic key, and she could never make it
quite clean; when the stain was gone off from one side, it came again on
the other.

Blue Beard returned from his journey that same evening, and said he had
received letters upon the road, informing him that the business which
called him away was ended to his advantage. His wife did all she could
to convince him she was delighted at his speedy return.

Next morning he asked her for the keys, which she gave him, but with
such a trembling hand that he easily guessed what had happened.

"How is it," said he, "that the key of my closet is not among the rest?"

"I must certainly," said she, "have left it upstairs upon the table."

"Do not fail," said Blue Beard, "to bring it to me presently."

After having put off doing it several times, she was forced to bring him
the key. Blue Beard, having examined it, said to his wife:--

"How comes this stain upon the key?"
