Bonjour, pouvez vous corriger les choses qui sont fausses svp In the short story, the narrator has the paranoia and the schizophrenia. We can see the paranoia when he has for idea to kill the old man and he waits 7 nights for have the best time to kill him. He repeats himself he is not mad; we cans understand in this moment he doesn't have good mental health. We cans see the schizophrenia when he heard the heartbeat when the body of the old man is dead, he has auditory hallucinations. All of these elements make us understand that the narrator is not good in his head, he has insahity, and he is unstable.
