The espionage thriller Slow Horses will premiere its fifth season on Apple TV+ on Wednesday 24 September, with new episodes arriving weekly until the finale on 29 October. The series continues to adapt Mick Herron's Slough House novels, with this run based on the fifth book, London Rules.
The new season shifts focus to Roddy Ho, the team's eccentric tech specialist, when his colleagues grow suspicious of his glamorous new girlfriend. As a string of bizarre events unfolds across the capital, the disgraced intelligence officers must uncover how everything links together, guided by Jackson Lamb's belief that the 'London Rules' always apply.
Herron has confirmed the adaptation will include notable changes from the source material. He said he enjoyed the departures, adding that some were instigated by himself. The author's comments suggest that even readers familiar with the novels will find fresh twists.
Gary Oldman returns as Jackson Lamb, alongside Kristin Scott Thomas as Diana Taverner, Jack Lowden as River Cartwright, and Christopher Chung as Roddy Ho. Jonathan Pryce is also confirmed to reprise his role as David Cartwright, despite his character's apparent exit in the previous season.
Fans can rest assured that this is not the end for the Slow Horses. Seasons six and seven have already been greenlit, though season five marks the final run overseen by showrunner Will Smith. Hugo Weaving, who portrayed Frank Harkness, is expected to return for the sixth season rather than the fifth, according to the actor's own comments.
