To make Cathy hurt even more, Heathcliff marries Edgar's sister. Cathy's heart breaks and she gets sick. He goes to her and they declare their love for each other. He prays over her after she dies, "Catherine Earnshaw, may you not rest as long as I am living; you said I killed you - haunt me, then! The murdered DO haunt their murderers, I believe. I know that ghosts have wandered on earth. Be with me always - take any form - drive me mad! only do not leave me in this abyss, where I cannot find you! Oh, God! it is unutterable! I can not live without my life! I can not live without my soul!'
