Inform Edgar that I'd give the world to see his face again-that my heart returned to Thrushcross Grange in twenty-four hours after I left it, and is there at this moment, full of warm feelings for him, and Catherine! _I can't follow it though_-(these words are underlined)-they need not expect me, and they may draw what conclusions they please; taking care, however, to lay nothing at the door of my weak will or deficient affection.

Tell Edgar that I'd give the world to see his face again - that my heart returned to Thrushcross Grange twenty-four hours after I left it, and is full of warm feelings for him, and Catherine! But they need not expect me, although not through any lack of affection for them.
