At the end of the year, to a day, Boots came back to the hill to look at his dappled colt, but before he reached there he saw a light in the sky and heard a sound as of thunder. The sound drew nearer and nearer, and then Boots saw the colt coming to meet him, and the noise was made by its hoofs, for it was so huge that the earth trembled under it as it came; and if its coat had been like satin before, now it shone like glass, so that the light was reflected all about it, and that was what Boots had seen. “By my faith,” cried Boots, “never have I beheld such a horse before. The King himself hath not another like it.” “That is true,” answered the steed. “And now, Master, the time has come for you to ride me out into the world, and together we will make your fortune.” Then Boots tried to mount, but Dapplegrim (for so Boots named the horse) was so huge that he was obliged to lie down before his master could get upon his back. Once Boots was up, away the horse went, so fast that the wind whistled past their ears, and they never stopped nor stayed until they came to the castle of the King of the country. Here Boots knocked at the door and asked the King if he might take service with him, and the King could have jumped for joy at the thought of having him. For never in his life before had he seen such a horse as Dapplegrim; and as for Boots, the King was sure that only a hero could be the master of such a steed. So now Boots was one of the King’s own men, and soon he became such a favourite that the King would have him always by his side, and talked to him more than to anyone else. But this made the noblemen who were about the castle very jealous. And not only did they have to make way for Boots, but all their own horses had to be taken out of the castle stable so that Dapplegrim might have the more room. Before long they began to plot and plan as to how they could rid themselves of Boots, and his great grey steed as well. Now, though the King of that country was very rich and powerful, he was so sad that he was never seen to smile, for he had had only one child, a daughter, and her a troll had stolen away. The troll kept her a prisoner in his house at the top of a great glass hill. This hill was as slippery as ice and as steep as a house. Many princes and brave men had tried to rescue the Princess, for she was as beautiful as the day, and the King had promised her in marriage to anyone who would bring her back to him. None had succeeded, however, and those who had tried had always lost their lives; for though the King had promised her as a wife to whoever could save her, he had also sworn to cut off the heads of all those who tried and failed. Now one day several of the noblemen who were jealous of Boots came to the King and told him that Boots had been saying this and that, and that he could ride up the hill on Dapplegrim as easily as not, and could rescue the Princess if only the King would ask him to.
