Since 1997 author Lee Child has been overseeing the world of Jack Reacher. There are the novels, of course (one released almost every year, now mostly written by Child's younger brother Andrew) and a pair of Tom Cruise movies (in 2013 and 2016).

Following his team-up with the 110th in season 2, and the subsequent takedown of tech mogul Shane Langston, Lee Child has his anti-hero tackling human trafficker Zachary Beck in the latest instalment, which is adapted from the author's seventh book, Persuader.

The "Jack Reacher" author Lee Child told Business Insider he wants his book about the opioid crisis, "The Midnight Line," to be adapted for the show.
