Slow Horses returns for season 6 on September 16. Apple TV has confirmed the premiere date for the spy thriller, which brings back Kristin Scott Thomas as Diana Taverner.
The show is also welcoming BAFTA-winner Lenny Rush. According to Deadline, Rush joins the cast for the new season.
Season 6 opens with the Slow Horses on the run after another scheme orchestrated by Scott Thomas's Diana Taverner. The season will feature the series' blend of tradecraft, betrayal, and gallows humour.
Rush's casting marks a significant change for season 6 of the espionage drama. The spy world rarely stays quiet for long in Slough House, and the new addition is expected to raise the stakes.
