The first episode of Slow Horses season six is now streaming on Apple TV. The six-episode season will continue with one episode each Wednesday through October 21.
Apple released a trailer for the season in August, confirming the September 16 premiere and the weekly schedule. Its season-six material also confirms Olivia Cooke’s return as Sidonie “Sid” Baker. Those details were announced ahead of the premiere, while the streaming availability is the material change for viewers today.
The schedule means the finale is set for October 21 if Apple maintains the announced weekly plan. Apple has not said that all six episodes will be released at once, so subscribers looking to binge the season should not expect a complete-season drop based on the company’s published schedule. The series page and Apple TV app remain the reliable places to check availability in a specific region.
