The Thief and his Master

Then the father and son set out homeward. On the way a carriage comes driving by. Hereupon the son says to his father, "I will change myself into a large greyhound, and then you can earn a great deal of money by me." Then the gentleman calls from the carriage, "My man, will you sell your dog?" "Yes," says the father. "How much do you want for it?" "Thirty thalers." "Eh, man, that is a great deal, but as it is such a very fine dog I will have it." The gentleman takes it into his carriage, but when they have driven a little farther the dog springs out of the carriage through the window, and goes back to his father, and is no longer a greyhound.

They go home together. Next day there is a fair in the neighbouring town, so the youth says to his father, "I will now change myself into a beautiful horse, and you can sell me; but when you have sold me, you must take off my bridle, or I cannot become a man again." Then the father goes with the horse to the fair, and the master-thief comes and buys the horse for a hundred thalers, but the father forgets, and does not take off the bridle. So the man goes home with the horse, and puts it in the stable. When the maid crosses the threshold, the horse says, "Take off my bridle, take off my bridle." Then the maid stands still, and says, "What, canst thou speak?" So she goes and takes the bridle off, and the horse becomes a sparrow, and flies out at the door, and the wizard becomes a sparrow also, and flies after him. Then they come together and cast lots, but the master loses, and betakes himself to the water and is a fish. Then the youth also becomes a fish, and they cast lots again, and the master loses. So the master changes himself into a cock, and the youth becomes a fox, and bites the master's head off, and he died and has remained dead to this day.
