Apple TV+ Keeps 'Slow Horses' Running with a Season 6 Renewal

Apple TV+ continues to ride the success of Slow Horses, which has been commissioned to trot out to a six-episode Season 6 less than a week after the Season 4 finale. (Season 5 was greenlit in January 2024, a few days after the conclusion of Season 3.) Based on the Mick Herron thrillers, The Slough House Series, comprised of nine novels and five short stories, Season 6 will be the first to combine novels after the first five seasons, each of which adapted the first five full-length best sellers. Seasons 1 through 4 covered Slow Horses, Dead Lions, Real Tigers, and Spook Street; the forthcoming Season 5 will cover the events from London Rules.

Season 6, on the other hand, will be a mashup of 2019’s Joe Country and 2021’s Slough House, leaving only 2022’s Bad Actors and the forthcoming Clown Town, due out in 2025, for future seasons to cover. Apple TV+ did not call Season 6 “the final season,” nor did it hint that the show may end soon. However, with the commissioning of the Slow Horses “companion” series Down Cemetary Road, it’s clear that Apple sees the end of the road for its most popular show and is prepping a replacement ahead of the original series coming to an end.

Apple TV+’s Jay Hunt said in the press release, “Audiences around the world have fallen in love with the Slow Horses, and I’m delighted that Gary Oldman will be leading this star-studded cast on another acerbic and action-packed adventure.” Oldman (Parthenope) leads the cast as Jackson Lamb, the head of Slough House, with Jack Lowden (The Gold) as River Cartwright and Kristen Scott Thomas (Gosford Park) as Diana Taverner, rounding out the center trio who keep the outcasts limping along.
