He decided to marry the daughter of a local squire and sent his father to ask for her hand, telling him to tell the squire that he was a Master Thief. The squire agreed, if the son could steal the roast from the spit on Sunday. The son caught three hares and released them near the squire's kitchen, and the people there, thinking it was one hare, went out to catch it, and the son got in and stole the roast.
The priest made fun of him, and when the Master Thief came to claim his reward, the squire asked him to prove his skill further, by playing some trick on the priest. The Master Thief dressed up as an angel and convinced the priest that he was come to take him to heaven. He dragged the priest over stones and thorns and threw him into the goose-house, telling him it was purgatory, and then stole all his treasure.
The squire was pleased, but still put off the Master Thief, telling him to steal twelve horses from his stable, with twelve grooms in their saddles. The Master Thief prepared and disguised himself as an old woman to take shelter in the stable, and when the night grew cold, drank brandy against it. The grooms demanded some, and he gave them a drugged drink, putting them to sleep, and stole the horses.
