The epistolary story consists of letters written from one character to another or moves between characters. The convention of the story may also include that of a monologue spoken aloud by one character to another.
The variations include the narrator speaking in intimate confessional to a friend or lover. Or, he may present his case to a jury or a mob. The narrator could pour out his heart in a love letter that he knows
(and we know) he will never send.
This style is the opposite of what's employed in a story told to the reader. The listener as well as the teller becomes involved in the action. Readers become eavesdroppers with all the ambiguous intimacy that position entails.
