‘Slow Horses’ Season 4: All We Know

Gary Oldman’s character, Jackson Lamb, will return to Apple TV+ for the fourth and fifth seasons of “Slow Horses.” The series, based on Mick Herron’s “Slough Horses” book series, has been confirmed for renewals due to high demand. The show has successfully attracted a wide audience, including fans of spy thrillers.

Oldman stars as Jackson Lamb, a spymaster with a unique problem, leading the Slough House faction composed of British intelligence agents who’ve been sidelined. The series is rooted in Herron’s book series, which currently comprises eight titles with a ninth on the way. Apple TV+ has been releasing seasons at a brisk pace. “Slow Horses” stands out as one of the few shows on the platform to secure a fifth season, with “For All Mankind” also reaching this milestone.


The agents of Slough House face tedious and monotonous workdays under Lamb’s leadership. However, their missions soon become essential to protecting British society. These characters, unlike the typical charismatic spies depicted onscreen, bring a refreshing perspective to the genre. Gary Oldman has expressed his enthusiasm for the role and has indicated he might conclude his career with this show. In a Deadline interview, Oldman discussed the possibility of wrapping up his acting career with “Slow Horses.”

The fourth season will follow Herron’s fourth book, Spook Street. The season begins with a bombing that reveals personal secrets, unsettling the already shaky foundations of Slough House. The storyline will also address River’s acquisition of the “Footprint” file, believed to be destroyed but with existing copies. The agents will be drawn into a terror attack in a crowded shopping area.

Regarding character relationships, showrunner Will Smith told Decider that the potential romantic dynamic between River and Louisa will be explored, though it will remain true to the book’s character dynamics. Smith described the evolving relationship as “messy.”

Season four will also provide a glimpse into Jackson Lamb’s living space for the first time, giving viewers a deeper look into his personal life. Speaking to Indiewire, Oldman revealed that Lamb’s flat would reflect his character’s chaotic nature, with books strewn around and creatively used furniture.


The cast of the fourth season includes several new members such as Hugo Weaving, Tom Brooke, Ruth Bradley, Joanna Scanlan, and James Callis. They will join returning cast members Gary Oldman, Kristin Scott Thomas, Olivia Cooke, Jack Lowden, Jonathan Pryce, Steven Waddington, Rosalind Eleazar, Saskia Reeves, and Paul Higgins, as reported by Deadline.

Release Date

According to a Decider interview with showrunner Will Smith in December 2023, the fourth season is expected to premiere before the end of 2024. Fans will not have to wait more than a year for the new season.
