The Poor Miller's Boy and the Cat

An old miller who did not have a family of his own wanted to retire and leave his mill to one of his three apprentices. All he wanted from them was to bring him the finest horse ever to be seen. Hans, one of the apprentices, found a cat which promised to find him the most beautiful horse only if he served her for seven years. Hans did not have that much to lose so he agreed. The seven years passed.
He returned to the mill. Everyone made laugh of him but then a beautiful princess came riding the most magnificent horse. Who inherited the mill and what happened with the cat? Find out in "The Poor Miller's Boy and the Cat".
