"How unjust was the fist a little ago!" said the rider of the black horse. When all was over the rider of the black horse said, "Are you willing to return home now?" "Yes," said O'Cronicert, "very willing." They then rose, and went to the stable: and the black horse was taken out; and they leaped on its back, and went away. The rider of the black horse said to O'Cronicert, after they had set off, "Do you know who I am?" "I do not," said O'Cronicert. "I am a brother-in-law of yours," said the rider of the black horse; "and though my sister is married to you there is not a king or knight in Erin who is a match for her. Two of your vows are now broken; and if you break the other vow you shall lose your wife and all that you possess." They arrived at O'Cronicert's house; and O'Cronicert said, "I am ashamed to go in, as they do not know where I have been since night came." "Hoo!" said the rider, "they have not missed you at all. There is so much conviviality among them, that they have not suspected that you have been anywhere. Here are the two teeth that you knocked out of the front of your wife's mouth. Put them in their place, and they will be as strong as ever." "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." "Let them go," said his wife. "I will not," said he. 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.
