‘ (...) And I pray one prayer—I repeat it till my tongue stiffens—Catherine Earnshaw, may you not rest as long as I am living; you said I killed you—haunt me, then! The murdered dohaunt 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 cannot live without my life! I cannot live without my soul!’

Wuthering Heights, Emily Bronte (ch. 16)
