Introduction In fictional writings, style is a term that is used to describe a set of norms for classifying writings, speech, and other art forms. These norms are formed by conventions but change over time as other new styles are developed and older ones are discarded. Classification of fictional works makes use of one or more of the styles and a piece of writing may fall under more than one genre of writing and the style used defines the author’s interactions with the environment and his/her experiences in such interactions. The paper aims to explore the use of style through an analysis of fictional works by American writer and poet Edgar Allan Poe (January 19, 1809 – October 7, 1849). Discussion Edgar Allan Poe is best known for his writings of horror fiction, crime and detective fiction, comedy, and satire. He wrote several short stories, some of which were published after his death. These include Ligaea (1858), The Fall of the House of Usher (1858), William Wilson (1839), and The Murders in the Rue Morgue (1841) among others. For the current study of style in Poe’s works, we shall consider The Murder in the Rue Morgue and The Purloined Letter for which we shall study three styles. Detective Fiction The Purloined Letter begins with an unknown narrator in the company of a friend, C. Augustine Duplin while pondering the murders in the Rue Morgue. The story proceeds by describing the arrival of the prefect of the Parisian police force by the name of Monsieur G-.

He then engaged the lady in a discussion. As he prepared to leave, he left his letter and took the lady’s; the Prefect also explains how important D—— is to the lady. The prefect also notifies Dupin that they had searched the room where D—— stayed, behind the wallpapers and under the carpets, but had not found the letter. They had even inspected the tables and chairs using microscopes and even the cushion but the letter was still unavailable. Dupin then asks for the description of the letter upon which the prefect gives the details from the memorandum book. The perfect returned a month later but discovered that Dupin had not found the letter despite being promised a huge reward that had been recently doubled. The perfect told Dupin that he will offer 50,000 francs to anyone who could obtain the letter that was becoming more and more important by the day. On hearing of this offer, Dupin told the Prefect to sign the cheque so that he can give him the letter, he signed the cheque and handed it to Dupin who in turn opened an escritoire, took out the letter, and handed it over to the Prefect. After determining that it was the original letter, th
