Tell-Tale heart scene

"You should have seen how wisely I proceeded -- with what caution -- with what foresight, with what dissimulation, I went to work!And every night about midnight I turned the latch of his door and opened it oh, so gently! And then, when I had made an opening sufficient for my head, I put in a dark lantern all closed, closed so that no light shone out, and then I thrust in my head. Oh, you would have laughed to see how cunningly I thrust it in! I moved it slowly, very, very slowly, so that I might not disturb the old man's sleep. It took me an hour to place my whole head within the opening so far that I could see him as he lay upon his bed."
