But when nobody believes the story, Harry decides to track her down before she strikes again. Upon finding her, he is seduced by her beauty and cannot kill her. Instead, he captures and imprisons her in a cage in his cellar. Now a prisoner, she must convince Harry to feed her, or she will slowly die.
