In Bamborough Castle once lived a king who had a fair wife and two children, a son named Childe Wynd and a daughter named Margaret. Childe Wynd went forth to seek his fortune, and soon after he had gone the queen his mother died. The king mourned her long and faithfully, but one day while he was hunting he came across a lady of great beauty, and became so much in love with her that he determined to marry her. So he sent word home that he was going to bring a new queen to Bamborough Castle. Princess Margaret was not very glad to hear of her mother's place being taken, but she did not repine but did her father's bidding. And at the appointed day came down to the castle gate with the keys all ready to hand over to her stepmother. Soon the procession drew near, and the new queen came towards Princess Margaret who bowed low and handed her the keys of the castle. She stood there with blushing cheeks and eye on ground, and said: “O welcome, father dear, to your halls and bowers, and welcome to you my new mother, for all that's here is yours,” and again she offered the keys. One of the king's knights who had escorted the new queen, cried out in admiration: “Surely this northern Princess is the loveliest of her kind.” At that the new queen flushed up and cried out: “At least your courtesy might have excepted me,” and then she muttered below her breath: “I'll soon put an end to her beauty.”
That same night the queen, who was a noted witch, stole down to a lonely dungeon wherein she did her magic and with spells three times three, and with passes nine times nine she cast Princess Margaret under her spell. And this was her spell:
  I weird ye to be a Laidly Worm,
    And borrowed shall ye never be,
  Until Childe Wynd, the King's own son

  Until the world comes to an end,
    Borrowed shall ye never be.
So Lady Margaret went to bed a beauteous maiden, and rose up a Laidly Worm. And when her maidens came in to dress her in the morning they found coiled up on the bed a dreadful dragon, which uncoiled itself and came towards them. But they ran away shrieking, and the Laidly Worm crawled and crept, and crept and crawled till it reached the Heugh or rock of the Spindlestone, round which it coiled itself, and lay there basking with its terrible snout in the air.
Soon the country round about had reason to know of the Laidly Worm of Spindleston Heugh. For hunger drove the monster out from its cave and it used to devour everything it could come across. So at last they went to a mighty warlock and asked him what they should do. Then he consulted his works and his familiar, and told them: “The Laidly Worm is really the Princess Margaret and it is hunger that drives her forth to do such deeds. Put aside for her seven kine, and each day as the sun goes down, carry every drop of milk they yield to the stone trough at the foot of the Heugh, and the Laidly Worm will trouble the country no longer. But if ye would that she be borrowed to her natural shape, and that she who bespelled her be rightly punished, send over the seas for her brother, Childe Wynd.”
All was done as the warlock advised, the Laidly Worm lived on the milk of the seven kine, and the country was troubled no longer. But when Childe Wynd heard the news, he swore a mighty oath to rescue his sister and revenge her on her c............
