"Come in with me," said O'Cronicert to the rider of the black horse.
"I will not: I disdain to go in," said the rider of the black horse.
The rider of the black horse bade O'Cronicert good-bye, and went away.
O'Cronicert went in; and his wife met him as she was busy waiting on the gentlemen. He asked her pardon, and put the two teeth in the front of her mouth, and they were as strong as ever. She said, "Two of your vows are now broken." No one took notice of him when he went in, or said "Where have you been?" They spent the night in eating and drinking, and the whole of the next day.
In the evening the king said, "I think that it is time for us to be going"; and all said that it was. O'Cronicert said, "You will not go to-night. I am going to get up a dance. You will go to-morrow."
The dance was set a-going that night. They were playing away at dancing and music till they became warm and hot with perspiration. They were going out one after another to cool themselves at the side of the house. They all went out except O'Cronicert and his wife, and a man called Kayn Mac Loy. O'Cronicert himself went out, and left his wife and Kayn Mac Loy in the house, and when she saw that he had broken his third vow she gave a spring through a room, and became a big filly, and gave Kayn Mac Loy a kick with her foot, and broke his thigh in two. She gave another spring, and smashed the door and went away, and was seen no more. She took with her the Tower of Castle Town as an armful on her shoulder and a light burden on her back, and she left Kayn Mac Loy in the old tumble-down black house in a pool of rain-drip on the floor.
At daybreak next day poor O'Cronicert could only see the old house that he had before. Neither cattle nor sheep, nor any of the fine things that he had was to be seen. One awoke in the morning beside a bush, another beside a dyke, and another beside a ditch. The king only had the honour of having O'Cronicert's little hut over his head. As they were leaving, Murdoch Mac Brian remembered that he had left his own foster-brother Kayn Mac Loy behind, and said there should be no separation in life between them and that he would go back for him. He found Kayn in the old tumble-down black house, in the middle of the floor, in a pool of rain-water, with his leg broken; and he said the earth should make a nest in his sole and the sky a nest in his head if he did not find a man to cure Kayn's leg.
