For many UK viewers, January has become synonymous with a new, gripping Harlan Coben adaptation arriving on Netflix. This year's offering, Run Away, released on 8 January 2026, has continued the tradition with a tense story starring James Nesbitt and Ruth Jones.
The Runaway Success of Run Away
The series follows Simon Greene, a father plunged into a desperate search for his missing daughter, Paige. His quest quickly spirals, entangling him in a sinister cult and making him a target for police investigation. Critics have embraced the show, awarding it an impressive 81% score on Rotten Tomatoes. Christopher Stevens of the Daily Mail dubbed it a ‘soap packed full of steroids’, while The Upcoming praised its execution as ‘exceedingly well’ done.
However, the show's breakneck pace presents a familiar problem for dedicated streamers: its eight-episode run is over all too quickly. While other Coben adaptations on Netflix offer a similar fix, they are equally finite, leaving fans searching for more sustained suspense.
Unlock Netflix's Hidden Thriller Library
Fortunately, there is a clever workaround to discover a treasure trove of suspense beyond the platform's standard recommendations. Netflix uses a system of numerical genre codes, and by altering a web browser URL, you can access entire categories hidden from the main interface.
To unlock every TV thriller available in your region, simply go to Netflix.com in your browser (this does not work in the apps) and change the URL to: https://netflix.com/browse/genre/4366. This will take you directly to the ‘Mystery Series’ genre page, showcasing a complete list uncurated by the personal algorithm.
