The rising action is when the narrator is preparing to kill the old man. during this time each night at midnight he spends an hour slowly opening the old man's door, he doesnt kill him any of these nights cause the man's "evil eye" is closed.
"Villains! dissemble no more! i admit the deed!~~Tear up the planks! Here, here!~~It is the beating of his hideous heart!"
The climax is when the narrator actually kills the old man, during this night the old man's eye is open and the narrator springs apon him and smothers him in his matress, afterwords he dismembers the body and hides it under the floorboards.
The falling action starts when the cops arrive and start questioning the narrator. all the while the narrator can hear the mans heart beating and it gets louder and louder while the cops talk to him.
The story is resolved when the heart beating becomes to much for him and he confesses screaming "Villains! dissemble no more! i admit the deed!~~Tear up the planks! Here, here!~~It is the beating of his hideous heart!"
The theme is that omater how mentally distant or how much they think they are right remorse or regret will settle in one way or another. in this story the beating of the heart represents that even if the narrator says the old man deserved to die he still in some form regrets it.
