Just in general, I wish “fictional non-fiction” were a bigger thing. I would love to get a massive crate of random documents and clippings that tell a very complex, nonlinear story with lots of red herrings & easily missed detailshttps://twitter.com/webdevmason/status/986283423370113024 …
I actually think you can tell a much better character story, e.g. through personal letters — choice of stationary, handwriting, signature, whether or not there's a coffee stain at the edge. Could be very, very rich.
