Write me a closing sentence for this paragraph? I will pick best answer.?

The total effect of the Tell-Tale Heart by Edgar Allen Poe is an unnerving, eerie feeling of fright and horror. The entire story focuses on the narrator attempting to prove his sanity to the reader. He tells of his caution and cleverness of killing the old man and concealing the body. Elements of this story such as repetition, imagery, figurative language, dark humor and the diction, contribute to the overall effect; they compile an image that implants itself into the reader’s mind.
