Overview
- Apple TV announced on June 11 that Slow Horses Season 6 will premiere on Sept. 16, 2026 and will release one episode weekly on Wednesdays through Oct. 21.
- The season adapts two of Mick Herron’s books, Joe Country and Slough House, into a single six-episode arc that the official logline frames as the Slow Horses being forced to go on the run.
- Gary Oldman and the core Slough House ensemble are returning while BAFTA winner Lenny Rush joins the cast in a role the studio is keeping under wraps.
- Gaby Chiappe is credited as the season’s adapter and showrunner with Adam Randall directing, marking a handover from the series’ previous leadership that producers say could change the show’s flavour.
- Apple and See-Saw Films have already started work on Season 7 to adapt the next book, reflecting the streamer’s continued investment in the award-winning franchise and its future run on the service.
