What Will Happen in Season 5 Of Slow Horses?
Season 5 is based on Mick Herron’s award-winning novel, London Rules. In the new season, the team grows suspicious when Roddy Ho gets a glamorous new girlfriend.
But when more and more strange events start happening across London, the team tries to find out what is really going on. Diana and Lamb want to know if Roddy’s girlfriend is linked to these unusual events.
A trailer for Season 5 was released earlier this month with the mysterious tagline: “A compromised agent, a destabilized London, and a can of paint. Slow Horses returns for a new season September 24th, 2025 on Apple TV+.”
The trailer teases Slough House under lockdown and the team pushing back as London faces fresh threats.
Preview coverage flags a mass shooting in a public square, a divisive election roiling London, and even an attempted hit on a Slough House agent.
The trailer also hints at tension between River and Lamb over River’s place at Slough House.
The official synopsis of Season 5 reads as: “In season 5 of ‘Slow Horses,’ everyone is suspicious when resident tech nerd Roddy Ho has a glamorous new girlfriend, but when a series of increasingly bizarre events occur across the city, it falls to the Slow Horses to work out how everything is connected. After all, Jackson Lamb knows that in the world of espionage, the London Rules — cover your back — always apply.”
Season 5 promises more action, mystery, and humor of Slough House. Viewers are eagerly anticipating the new season which begins on September 24th, 2025.
