Recs if you like The Gray Man...

Books that were adapted into movies (not tv shows). Let's make this list as long as possible!

(going to only add the first book in a series)

A list of (mostly action) books about spies, secret agents, assassins, people faking their identities, bringing down a corrupt politician and jumping out of a window while bebop jazz plays in the background.

Note: I haven't read all of these! And I'm always looking for more, so I'm totally open to recs :)!

Books that have been adapted as Netflix Originals More to be added!
