she was a bad Princess.
She was pretty enough. No one could be more lovely or more entertaining than she - but what good did that do? She was a wicked witch, who was responsible for many handsome Princes' losing their lives. She had decreed that any man might come to woo her. Anybody might come, whether he were Prince or beggar, it made no difference to her, but he must guess the answer to three questions that she asked him. If he knew the answers, she would marry him and he would be King over all the land when her father died. But if he could not guess the right answers, she either had him hanged or had his head chopped off. That was how bad and wicked the beautiful Princess was.
The old King, her father, was terribly distressed about it, but he could not keep her from being so wicked, because he had once told her that he would never concern himself with her suitors - she could do as she liked with them.
