Which of the following excerpts from the short story “the tell-tale heart” by edgar allan poe best demonstrates the unreliability of the narrator? you should have seen how wisely i proceeded—with what caution—with what foresight—with what dissimulation i went to work! i heard many things in hell. how, then, am i mad? hearken! and observe how healthily—how calmly i can tell you the whole story. and then, when i had made an opening sufficient for my head, i put in a dark lantern, all closed, closed, 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.
