My novel is an epistolary à la Bram Stoker's Dracula and there are some scenes that simply have no one around to record. Modern epistolary stories, such as the trend of “found footage” movies like Apollo 18, tend to leave these undocumented scenes blank to add mystery.
I feel my story has expository scenes which simply can’t reside in an epistolary (largely because this is telling of true events in a fictional setting).
I am certain with enough effort, I could concoct some way to put the expository elements into someone’s journal, and then have that journal find its way to the narrator somehow. But it will be a large investment and add distracting pages. Because the protagonist journal exposes the central plot, I would like to know what value-add a story gets by maintaining a purist first-person POV.
The fastest way to get through exposition is a 3P Deep narrator. Will this tend to devalue an epistolary story?
Note: It is Vol. I of III; the sequel may well be 3PD straight through, but the world (literary universe–not the planet literally) essentially reacts to the events discovered in the footage.
