<P> That will do to explain my secret, as well as the other . I've no more business to marry Edgar Linton than I have to be in heaven; and if the wicked man in there, had not brought Heathcliff so low I shouldn't have thought of it . It would degrade me to marry Heathcliff now; so he shall never know how I love him; and that, not because he's handsome, Nelly, but because he's more myself than I am . Whatever our souls are made of, his and mine are the same, and Linton's is as different as a moonbeam from lightning, or frost from fire . </P> <P> Heathcliff, eavesdropping outside, hears only that she is cognizant of the reality that a marriage to him would "degrade" her . Immediately, he embarks on a mysterious three - year absence . </P> <P> This decision can be regarded as the beginning of Heathcliff's revenge on the Lintons . He later returns, a wealthy and distinguished gentleman, to find Cathy married to Edgar and living at Thrushcross Grange . The moment of his return is a telling one . After Cathy runs outside to greet him, </P> <P> Mr. Linton walked to a window on the other side of the room that overlooked the court . He unfastened it, and leant out . I (Nelly) suppose they were below, for he exclaimed quickly: "Don't stand there, love! Bring the person in, if it be anyone particular ." Ere long, I heard the click of the latch, and Catherine flew up - stairs, breathless and wild; too excited to show gladness: indeed, by her face, you would rather have surmised an awful calamity . </P>
