I was browsing in Books-A-Million and I noticed something strange...
Robert B Parker, the author of Appaloosa, Brimstone and Resolution (IMHO 3 great novels based around Virgil Cole and Everett Hitch) has a fourth book out

, despite being deceased

The fourth book is called "Blue Eyed Devil" fantastic read. Took me two days, but I am a rather quick reader.
Much to my surprise

I observed a 5th book based on the duo of Cole and Hitch by the screenwriter of Appaloosa Robert Knott, titled "Ironhorse".
I did not buy it as it was hardcover but hopefully it's decent and Cole and Hitch can continue their story with further novels.
