What to Expect in Season 5
Season 5 places the spotlight on the office’s tech expert, Roddy Ho. The official plot centers on the team’s suspicion when Roddy Ho gets a glamorous new girlfriend. At the same time, a string of strange and increasingly dangerous events begins to unfold across London. It falls to the Slow Horses to connect the dots and uncover how everything is linked.
The logline from Apple TV+ states:
“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.”
The season will see the return of Gary Oldman as the brilliant but irascible Jackson Lamb, Jack Lowden as River Cartwright, and Kristin Scott Thomas as MI5’s Deputy Director General, Diana Taverner. New faces joining the cast include Nick Mohammed as Zafar Jaffrey, the Mayor of London, and Hiba Bennani as Tara, Roddy Ho’s new girlfriend.
