Season 4 of the beloved espionage thriller series Slow Horses is highly anticipated by fans. The show, based on Mick Herron’s Slough House book series, follows the adventures of MI5 agents who are considered misfits. The third season ended with a number of character rifts and cliffhangers, leaving fans eager for more.
Apple TV+ renewed Slow Horses for both Season 3 and Season 4 in June 2022. Fans can expect Season 4 to premiere on Wednesday, September 4, 2024. The new season will consist of six episodes, with a one-episode weekly release schedule until the finale on October 2.
