Paranoid Personality Disorder

"A Tell-Tale Heart"- Edgar Allen Poe


No doubt I now grew VERY pale; but I talked more fluently, and with a heightened voice. Yet the sound increased -- and what could I do? It was A LOW, DULL, QUICK SOUND -- MUCH SUCH A SOUND AS A WATCH MAKES WHEN ENVELOPED IN COTTON. I gasped for breath, and yet the officers heard it not. I talked more quickly, more vehemently but the noise steadily increased. I arose and argued about trifles, in a high key and with violent gesticulations; but the noise steadily increased. Why WOULD they not be gone? I paced the floor to and fro with heavy strides, as if excited to fury by the observations of the men, but the noise steadily increased. O God! what COULD I do? I foamed -- I raved -- I swore! I swung the chair upon which I had been sitting, and grated it upon the boards, but the noise arose over all and continually increased. It grew louder -- louder -- louder! And still the men chatted pleasantly , and smiled. Was it possible they heard not? Almighty God! -- no, no? They heard! -- they suspected! -- they KNEW! -- they were making a mockery of my horror! -- this I thought, and this I think. But anything was better than this agony! Anything was more tolerable than this derision! I could bear those hypocritical smiles no longer! I felt that I must scream or die! -- and now -- again -- hark! louder! louder! louder! LOUDER! --
"Villains!" I shrieked, "dissemble no more! I admit the deed! -- tear up the planks! -- here, here! -- it is the beating of his hideous heart!"
