In Tell Tale Heart the narrator does not like the old mans vulture like eye. This is imagery because he is describing the eye He describes it as "The eye of a vulture- a pale blue eye, with a film over it" (Poe 78).
The narrator in Tell Tale Hearts would cautiously sneak into the old mans room. When he would talk about how he went into his room he used an again and again because he would repeat the same word over and over again. The sentence where he would repeat the word is "I undid the lantern cautiously- oh so cautiously- cautiously" (Poe 80)
The climax in this story is when the narrator kills the old man. This is the climax because we didn't expect the narrator to kill the old man and it was the turning point in the story.
