On arrival, She is shocked by her former fiancé's appearance - he has aged significantly and acts in a nervous manner. Gerald allows her to stay but insists in locking her into her room at night. While there she hears mysterious sounds from beyond her door. Intrigued by this, she steals a key and follows the strange sounds. She is startled by a weird frog-like human creature/humanoid??? that she finds roaming the castle corridors. The creature too is frightened and while trying to escape falls from a window, killing itself. Only then can Gerald reveal what has been going on. He tells her that the abomination that she saw was his ancestor and the original master of the keep. When his Uncle dies it became his turn to look after it. Now that the creature is dead and Gerald's obligation gone, he is again free to marry Kitty.
