According to a different source, this question refers to the story "The Tell-Tale Heart" by Edgar Allan Poe.
In this story, one of the main purposes of the author is to create suspense. This is usually done by describing the events of a story in a way that creates nervousness and anticipation in the mind of the reader.
Poe does this in several ways in lines 103-115. In these lines, Poe describes the speaker of the story looking in on the old man while he sleeps. The scene is described in extreme detail. The pace is very slow. Moreover, the narrator contradicts himself, revealing himself to be unreliable. All of these devices contribute to a sense of nervousness and anxiety in the reader, and therefore, a sense of suspense.
