Context: 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 can not find you! Oh, God! it is unutterable! I can not live without my life! I can not live without my soul!
