I'm hoping to finish this up in the next hour or so.
This has turned out to be a gripping read.
Maybe this is one where the story reminding me of other stories actually adds to the suspense. Based on a True Story is more layered than the book/film it reminds me of and which actually features by reference (so it is definitely meant to be based on it).
The additional layers make this a really interesting read.
The overwhelming question I have is: Who is L.?
