Following Slow Horse’s Season 4 finale earlier this month, Apple TV+ has announced that the spy thriller has been renewed for a sixth season just as Season 5 wraps production. 

Slow Horses, described as an “utterly brilliant” espionage thriller, has just concluded its fourth season on October 9 of this year. With Season 5 still awaiting a release date, the acclaimed series has just received a Season 6 renewal.

What to expect in Slow Horses Season 6?

Slow Horses is based on the Slough House book series by award-winning author Mick Herron. The sixth season will be adapted from the sixth and seventh novels in the book series, Joe Country and Slough House. 

Per the synopsis, Slow Horses “is a darkly humorous espionage drama that follows a dysfunctional team of British intelligence agents who serve in a dumping ground department of MI5 known un-affectionately as Slough House.”

It follows Jackson Lamb, a “brilliant but cantankerous leader of the spies, who end up in Slough House due to their career-ending mistakes as they frequently find themselves blundering around the smoke and mirrors of the espionage world.”

“Season six sees the Slow Horses on the run as Diana Taverner embroils them all in a fatally high-stakes game of retaliation and revenge,” the logline for Season 6 reads. 

The series stars Gary Oldman as Jackson Lamb, Jack Lowden as River Cartwright, Kristin Scott Thomas as Diana Taverner, Saskia Reeves as Catherine Standish, Rosalind Eleazar as Louisa Guy, Christopher Chung as Roddy Ho, Samuel West as Peter Judd, Aimee-Ffion Edwards as Shirley Dander, Ruth Bradley as Emma Flyte, Tom Brooke as J.K. Coe, Joanna Scanlan as Moira Tregorian, and Jonathan Pryce as David Cartwright.

While both Seasons 5 and 6 have yet to announce their respective release dates, you can catch up on the first four seasons on Apple TV+.
