The first sentence of the concluding paragraph uses the principal words from the quotations from each paragraph of the body of the paper. This summarizes those three paragraphs. The second and third sentences provide observations which can also be considered a summary, not only of the content of the paper, but also offers personal opinion which was logically drawn as the result of this study. The last sentence returns to the Edgar Allan Poe-Stephen King relationship that began this paper. This sentence also provides a "wrap-up" and gives the paper a sense of finality.
The first paragraph or so of an essay is usually the most important part of the whole essay to get "just right". Not only is it an opportunity to grab the reader's attention, but also a chance to set the agenda for the rest of the essay in terms of tone and content. Strictly speaking, there is no single "right" way to begin an essay — just as it's possible to write essays about countless subjects, so too is it possible to begin an essay in countless ways. However, most good beginnings to essays share certain qualities which, if taken into account, can greatly improve essay intros that may otherwise be lacking. See Step 1 below to get started.
