The story, "Tell-Tale Heart", is about a mentally ill fellow who is being "haunted by an evil eye". He wishes to prove his sanity to the readers/the police despite the fact that he has killed a man over his eye. He, of course, fails to prove himself. "I heard many things in hell. How, them, am I mad? Hearken! and observe how healthy-how calmly I can tell you the whole story."
The narrator lives in the same building as the narrator, being is caretaker and all. He says that the eye is like a vulture's with film on it. It caused his blood to boil whenever he saw it. "One of his eyes resembled that of a vulture-a pale blue eye, with film over it."
For the next eight nights, the narrator watched the old man sleep. He didn't watch the old man, but his EYE. He plotted ways to get rid of the eye. "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 my head in."
One evening, the old man woke up and screamed. The narrator pulls off the mattress and smothers him with the mattress until the heartbeat was no longer. He chops off the deceived man's head, legs, and arms off. Then he decides to hide the body parts underneath the floorboards. "With a loud yell, I throw open the lantern and leaped into the room. He shrieked once-once only, In an instant I dragged him to the floor and pulled the heavy bed over him."
Later that night, the neighbor heard the shriek and called the police, They soon arrived , stating that someone heard a scream. The narrator tries to convince them otherwise by saying that he screamed and that the old man was elsewhere. He brought them inside and used his manner to show that nothing was wrong. "The officers were satisfied. My manner had convinced them. I was singularly at case. They say, and while I answered cheerily, they chatted off familiar things."
The story ends with the narrator hearing a mysterious ticking noise. It grew louder and louder. He believes that the sound is that of the old man's heart and immediately confesses to the police.
"Villains! Dissemble no more! I admit the deed!-tear up the planks! -here,here!-it is the beating of his hideous heart!"
