To categorise texts, allows us to view the world from another perspective, and make sense of the world. This is the function of genre. This allows the responder to class texts even further into sub genres, which have conventions they follow to.

For that reason the genre allows classifying texts to certain elements create a sense of order. The conventions of both detective and mystery writing are very similar. This is due to that fact that they are both sub genres of crime writing. Furthermore they both have a crime committed, and a process of detective work occurs. Yet the difference between both sub genres is that detective fiction involves murder and mystery does not. Also mystery creates suspense, such as stretching scenarios where the responder knows more information than the characters in the story, while detective writing focuses more upon how the case is solved. Hence demonstrates that by categorising literature, the complexities are diminished as such.
Through the use of presenting a setting, Poe adheres to both sub genres. This is demonstrated through the citation of, ‘curling eddies of smoke that oppressed the atmosphere of the
