Well, it depends on the tone and style you want for your novel. You might consider a first-person narrator for a more intimate and personal story, or a third-person omniscient narrator for a broader perspective.
To start 'your narrator fanfiction', you should consider the setting. Is it in a modern city, a medieval village, or a far - off planet? Once you've decided on the setting, start writing about the narrator's first encounter in that place. For example, if it's a medieval village, the narrator might be arriving on horseback and seeing the village for the first time. They could describe the sights, sounds, and smells, which will draw the reader into the story.
Think about using a title that evokes mystery or suspense, such as 'The Veiled Murder' or 'Hidden Kill'. Also, consider titles that focus on the victim or the perpetrator, like 'The Victim's Silence' or 'The Killer's Confession'.
It's hard to say for sure without more context. It might be someone close to the wife, like a friend or family member, who has a unique insight into her life and is chosen to tell the story. Another possibility is that it's an unnamed omniscient narrator who knows everything about the situation.
In my opinion, Morgan Freeman could be an excellent narrator for a novel. His voice is deep, rich, and has a certain gravitas that can bring any story to life. He has a way of making the listener feel as if they are being told an important and engaging tale.
