I have to imagine his books were terrible if he only half-assed writing them between saving the world all the time (and maybe snuck in some secret clues for Mark along the way?)
It was more or less confirmed that Cecil was responsible for basically all the book sales in order to keep Nolan and his family financially situated, so it seems like they weren’t exactly flying off the shelves on their own.
Even if they weren’t racist, “The Man with the Invincible Gun” is just an absolutely terrible title for a book lol, so that probably din’t help.
