Slow Horses is a spy thriller series based on the novels by Mick Herron. The show follows a group of disgraced MI5 agents who are banished to Slough House, a dumping ground for failures and misfits. There, they are led by the rude and cunning Jackson Lamb, who often gets them involved in dangerous missions that no one else wants.
The series premiered on Apple TV+ in April 2022 and has been praised for its witty dialogue, complex characters, and gripping plot. The second season, based on the novel Dead Lions, aired in December 2022 and continued the adventures of the Slow Horses as they faced a new threat from Russia.
In June 2022, Apple TV+ announced that the series was renewed for two more seasons, which will be based on the novels Real Tigers and Spook Street. The third and fourth seasons are being filmed back-to-back, just like the first and second seasons.
But when can we expect to see Slow Horses season 4? Who will be in the cast? And what will be the story? Here is everything you need to know about the upcoming season of Slow Horses.
Slow Horses Season 4 Release Date
Although Slow Horses season 4 has not yet been given an official release date, we may make some reasonable predictions based on the past seasons. The first season debuted in April 2022, followed by the second in December 2022. That indicates that the two seasons were separated by eight months.
If the third and fourth seasons follow a similar course, we can anticipate seeing Slow Horses seasons 3 and 4 in late 2023 and mid-2024, respectively. This is only a hunch, though, and it could be altered based on the production timeline and other variables.

Slow Horses Season 4 Plot
Slow Horses season 4 will be based on the novel Spook Street by Mick Herron. In the book, a terrorist strike in London leaves scores of people dead, including River Cartwright’s illustrious spy grandfather. River learns that his grandfather may have been involved in some dubious activities and that he had a secret life that he was unaware of.
Lamb and his team are tasked with guarding a little boy who could have seen anything significant during the assault. They quickly learn, though, that the boy is not the only one with an interest in him and that strong forces are at work to have him silenced.
Lamb and his crew will encounter both new adversaries and stalwart allies who will put their loyalty and competence to the test as they work to solve the attack’s mystery and safeguard the boy.
Conclusion
One of the top spy programs on television right now is Slow Horses. It masterfully balances humour, drama, suspense, and action. Two additional seasons of the program have been ordered, and they will adapt Mick Herron’s upcoming two novels in the series. The fourth season of Spook Street will focus on River’s grandfather’s secrets and the effects of a terrorist attack in London.
