A thesis statement is a sentence in which the writer states the main idea or central point contained in his paper and his position on it. The arguments presented in his writing should then reflect and support his point of view. This means that the thesis statement should be focused and specific.

Such a thesis statement allows the writer to explore the obsession that the narrator has with the old man's 'evil eye' and the descriptions he gives it to emphasize its effect on him. The writer can then delve into how this obsession affects the narrator's thinking and his behaviour - which both display an abnormality. Finally, the writer can present detail as to how these drive the narrator to commit a desperate, fatal act and his responses later when he is so overwhelmed by what he believes he hears that he confesses to his malicious deed.
