The Prince was in despair, but Jack said nothing till his master was in bed. Then he put on the old cap he had got from the giant, and lo! in a minute he knew all that he wanted to know. So, in the dead of the night, when the beautiful lady called on one of her familiar spirits to carry her to Lucifer himself, Jack was beforehand with her, and putting on his coat of darkness and his slippers of swiftness, was there as soon as she was. And when she gave the handkerchief to the Devil, bidding him keep it safe, and he put it away on a high shelf, Jack just up and nipped it away in a trice! So the next morning, when the beauteous enchanted lady looked to see the Prince crestfallen, he just made a fine bow and presented her with the handkerchief. At first she was terribly disappointed, but, as the day drew on, she ordered another and still more splendid repast to be got ready. And this time, when the repast was over, she kissed the Prince full on the lips and said: "I have a task for you, my lover. Show me to-morrow morning the last lips I kiss to-night or you lose your head." Then the Prince, who by this time was head over ears in love, said tenderly, "If you will kiss none but mine, I will." Now the beauteous lady, for all she was possessed by seven devils, could not but see that the Prince was a very handsome young man; so she blushed a little, and said: "That is neither here nor there: you must show me them, or death is your portion." So the Prince went to his bed, sorrowful as before; but Jack put on the cap of knowledge and knew in a moment all he wanted to know. Thus when, in the dead of the night, the beauteous lady called on her familiar spirit to take her to Lucifer himself, Jack in his coat of darkness and his shoes of swiftness was there before her. "Thou hast betrayed me once," said the beauteous lady to Lucifer, frowning, "by letting go my handkerchief. Now will I give thee something none can steal, and so best the Prince, King's son though he be." With that she kissed the loathly demon full on the lips, and left him. Whereupon Jack with one blow of the rusty sword of strength cut off Lucifer's head, and, hiding it under his coat of darkness, brought it back to his master. Thus next morning when the beauteous lady, with malice in her beautiful eyes, asked the Prince to show her the lips she had last kissed, he pulled out the demon's head by the horns. On that the seven devils, which possessed the poor lady, gave seven dreadful shrieks and left her. Thus the enchantment being broken, she appeared in all her perfect beauty and goodness. So she and the Prince were married the very next morning. After which they journeyed back to the court of King Arthur, where Jack the Giant-Killer, for his many exploits, was made one of the Knights of the Round Table. V
