You are aware that I am no way blamable in this matter. What possessed him to turn listener? Heathcliff's talk was outrageous, after you left us; but I could soon have diverted him from Isabella, and the rest meant nothing. Now all is dashed wrong; by the fool's craving to hear evil of self, that haunts some people like a demon! Had Edgar never gathered our conversation, he would never have been the worse for it. Really, when he opened on me in that unreasonable tone of displeasure after I had scolded Heathcliff till I was hoarse for him, I did not care hardly what they did to each other; especially as I felt that, however the scene closed, we should all be driven asunder for nobody knows how long! Well, if I cannot keep Heathcliff for my friend-if Edgar will be mean and jealous, I'll try to break their hearts by breaking my own. That will be a prompt way of finishing all, when I am pushed to extremity! But it's a deed to be reserved for a forlorn hope; I'd not take Linton by surprise with it. To this point he has been discreet in dreading to provoke me; you must represent the peril of quitting that policy, and remind him of my passionate temper, verging, when kindled, on frenzy.
