Read it through once

I distinguished Mr. Heathcliff’s step, restlessly measuring the floor, and he frequently broke the silence by a deep inspiration, resembling a groan. He muttered detached words also; the only one I could catch was the name of Catherine, coupled with some wild term of endearment or suffering; and spoken as one would speak to a person present; low and earnest, and wrung from the depth of his soul. I had not courage to walk straight into the apartment; but I desired to divert him from his reverie, and therefore fell foul of the kitchen fire, stirred it, and began to scrape the cinders. It drew him forth sooner than I expected. He opened the door immediately, and said—“Nelly, come here—is it morning? Come in with your light.”
