One of these days, Dan Brown will start making a new novel, but this is not the day it happens.
Why would DB change the formula when it works, right? It would be like trying to reinvent the wheel!
But as long as people hoping he’ll use his literary capability to make something original buy his book (and frankly be disappointed by it), he’ll churn out variations of the same tune at the rate of one book every two years.
See you in another two years!
