Spy dramas often struggle to maintain their quality over multiple seasons, but Apple TV’s darkly comedic take on the genre has proven to be a notable exception. Centered around a group of disgraced British intelligence agents, the show has transformed career failures into one of streaming’s most consistent success stories.

This success has garnered another vote of confidence from Apple, arriving at a particularly timely moment for the franchise. With Season 6 just days away from its debut, the streamer has already secured plans for the series to extend well beyond its upcoming chapters.

‘Slow Horses’ has officially been renewed for Season 8 at Apple TV, with the announcement coming shortly after the show won an Emmy for Outstanding Directing in a Drama Series. The new season will feature six episodes and will adapt ‘Clown Town,’ the ninth novel in Mick Herron’s Slough House book series, continuing the show’s impressive track record of translating Herron’s espionage fiction directly to the screen.

Gary Oldman will reprise his role as Jackson Lamb, the brilliant yet notoriously unkempt leader of Slough House, the MI5 department where disgraced agents serve their professional purgatory. His performance has been the backbone of the series since its debut in 2022 and shows no signs of slowing down as the show delves deeper into Herron’s expanding catalog of source material.

This isn’t the first time Apple has swiftly secured the show’s future. Season 7 was confirmed last year, even before Season 6 had premiered, continuing a trend where the streamer has consistently greenlit new seasons ahead of the current one finishing its run. Season 7 will adapt Herron’s eighth novel, ‘Bad Actors,’ marking a return to the show’s usual one-book-per-season format after Season 6 combined two separate novels into a single run.

Season 6 itself is set to premiere Wednesday, adapting both ‘Joe Country’ and ‘Slough House’ into six episodes that will be released weekly through October. This expanded approach reflects the confidence Apple has in the franchise, even as it experiments with integrating multiple books into shorter seasons to maintain the show’s annual release schedule.

Executive producer Will Smith has previously indicated that the show could continue indefinitely, as long as both its star and source material remain available. He mentioned to TV Insider that Oldman has expressed a desire to portray Lamb “forever,” and with Herron still actively writing new entries in the Slough House series, there’s little reason the show couldn’t persist well beyond its currently confirmed seasons.

This trajectory has been supported by consistently strong reviews throughout the show’s run, including a rare perfect Rotten Tomatoes score for Season 2, along with a growing collection of Emmy, Golden Globe, and BAFTA accolades. With Herron’s ninth novel now confirmed as the foundation for Season 8 and no clear end in sight for the book series, ‘Slow Horses’ appears increasingly poised to remain one of Apple TV’s most reliable originals for years to come.
