Apple TV+ Renews ‘Slow Horses’ for Seasons 6 & 7, Reveals Plot Details
Apple TV+ has renewed its critically acclaimed espionage series, “Slow Horses,” for both a sixth and seventh season, with the sixth season set to adapt two novels from Mick Herron’s Slough House series.
The announcement follows the conclusion of Season 5, which aired its finale yesterday, October 28th, and immediately premiered a teaser trailer for the upcoming sixth season. Season 6 will be based on “Joe Country” and “Slough House,” the sixth and seventh books in Herron’s series, and will see the spies of Slough House on the run as Diana Taverner navigates a dangerous game of retaliation. This continuation signals Apple TV+’s confidence in the show’s growing popularity and critical acclaim.
The Season 5 finale teaser revealed a plot involving a stolen file containing the Slow Horses’ names, leading to a hunt for those responsible and a confrontation with River Harkness and his father, Frank (Hugo Weaving). Lamb, played by Gary Oldman, warns of a “bloodbath” and declares the need to address the “five Fs” – a darkly humorous moment characteristic of the series. As Deadline reported, the series is officially Apple TV+’s longest-tenured series.
Season 7 is already in development, with a plot centered around uncovering a mole within the British government. Fans can expect new episodes of “Slow Horses” to likely premiere in fall or winter 2026, continuing the show’s approximate one-season-per-year release schedule, as detailed in Entertainment Tonight. Officials have stated that production will begin swiftly, maintaining the series’ established pattern.
