This is a Supposal as termed by C.S. Lewis. Suppose a centurion wanted to search out what he had heard and experienced about a certain carpenter and see if there was anything of his he could find.
Voshen does this well. He has created a character with a sincere desire to investigate the claims of who Jesus is and any physical/material proof of his existence. I loved the twist at the end. That was very unique and creative.
My only complaint is the shortness of the narrative. But it is a novella!
