"there was something mysterious about his eye". the crazy man claims that he was going to kill the old man. i think this that this scene is important because it explains what the crazy man is doing and what is going on.
"is anyone there". the crazy man woke up the old man. so crazy man killed old man. he cut up all of the old mans body parts and put them under the floor board. i think this is important so that you know what going on.
"he had confessed to the murder".about an hour later the cops showed up. the cops came into the room and wanted to talk. he heard the old mans heart beat in his head and confessed to the murder out of fear. this is important because it is the most conflict.
