Watching through Amazon still means paying for Apple TV. A regular Prime membership does not include Slow Horses, so Prime members who want the show inside the Prime Video app need the Apple TV channel. Apple also includes 3 months of Apple TV when you buy an Apple device and redeem the offer within 90 days.
The same subscription covers other Apple originals, such as Ted Lasso and Silo. See our Ted Lasso Season 4 guide and Silo Season 3 ending explained.

What Season 6 is about
This season adapts Joe Country and Slough House, the sixth and seventh novels in Mick Herron’s Slough House book series. In Apple’s synopsis, the Slow Horses end up on the run after Diana Taverner pulls them into a deadly game of retaliation and revenge.
The premiere finds River bracing for his grandfather’s funeral while Lamb looks into the death of a former Slow Horse. Adam Randall directs the season, Gaby Chiappe adapted the books for television, and See-Saw Films produces for Apple TV.
Who is in the Season 6 cast
Gary Oldman returns as Jackson Lamb, the obnoxious boss of a dysfunctional team of MI5 agents. Jack Lowden plays River Cartwright, Kristin Scott Thomas plays Diana Taverner, Saskia Reeves plays Catherine Standish, Rosalind Eleazar plays Louisa Guy, Christopher Chung plays Roddy Ho, and Aimee-Ffion Edwards plays Shirley Dander.

Catching up on Seasons 1 to 5

More seasons are coming. Apple ordered a six-episode Season 7 in July 2025, adapted from Bad Actors, and on September 15, 2026, it announced Season 8, based on Clown Town, the ninth Slough House novel. Apple has not yet given Season 7 a premiere date.
