"Villains! Dissemble no more! I admit the deed- tear up the planks! here, here! - It is the beating of his hideous heart!"
The Narrator met an old man who he liked for he never wrong him or insulted him. But he had an evil eye that the narrator didn't like however. And every night for eight nights he snuck into the old man's house to watch him sleep.
On the eighth night however the old man woke for he heard the narrator sneaking in. And the narrator saw his eye which made him want to kill the old man. He jumped out and suffucated the old man with his bed. The old man screamed only once...
2 cops come and said that they received a report of yelling so the narrator tells them that he was yelling because of a dream. He invites them into the old man's house. But after a while he starts hearing a beating sound which he thinks is the old man's heartbeat. The beating gets louder and louder until he can't take it. He then yells out that he killed the old man and show them where he hid the corpse.
