Former Slough House members are being hunted in Slow Horses Season 6, which premiered on September 16, 2026. That suggests that the present members of the unit are in danger as well. Slow Horses Season 6 Episode 3 is going to take us closer to finding out who wants to kill all the Slough House members and why.We found out that Sidonie Baker (played by Olivia Cooke), aka Sid is still alive at the end of episode 2, and as the preview images for episode 3 suggest, she will play a big role in the rest of the season.What to expect from Slow Horses Season 6 Episode 3?Slow Horses Season 6 episode 3, titled Resurrection, will be released on Apple TV on September 30, 2026. The episode's preview images show us Sid and River (played by Jack Lowden) working together on something, Reece Nesmith (played by Lenny Rush) and Roddy (played by Christopher Chung) spending more time together, and a meeting between Lamb (played by Gary Oldman) and Diana (played by Kristin Scott Thomas).While Sid is revealed to be alive and pays River a secret visit, it is highly unlikely that River will trust her right away. MI5 initially sent Sid to Slough House in Season 1 to keep an eye on River and then faked her death when she was shot in the head. Since she is back after such a long time, we can assume that Sid knows something extremely important as to why former Slough House members are being targeted.While River won't trust Sid right away, it looks like he will work with her to find out who is behind the assassinations and why. Roddy has been keeping an eye on Reece Nesmith, the young son of Andrew Nesmith, who witnessed Frank Harkness killing his father. Reece is a valuable witness who needs to be protected, and we will see more of him and Roddy in Episode 3.Frank (played by Hugo Weaving) is still working with Damien Cantor (played by Harry Lloyd), who hired him to get information connected to Slough House. However, we still don't know why Cantor wants this information and what he plans to do with it. Slow Horses Season 6 episode 3 preview images show Sid and River running from someone, which suggests that they might get close to finding out more about Cantor's plans and if he's the one directly ordering the murders. View this post on Instagram Instagram PostStandish (played by Saskia Reeves) and Shirley (played by Aimee-Ffion Edwards) will go looking for Louisa (played by Rosalind Eleazar) because, as a former Slough House member, she could also be in danger. Moreover, Moira Tregorian (played by Joanna Scanlan) is also in danger. The assassins have already targeted her by staging a gas leak at her home. If Lamb's team doesn't get to her in time before the assassins do, she might become the next victim.In the upcoming episode, we will also see Diana Taverner deal with the consequences of her disastrous television interview with Cantor’s media operation. The interview exposed sensitive information about MI5 and Taverner’s past, including that she had something to do with Charles Partner's death.The interview wasn't just a bad look for Diana. It revealed that someone had access to highly sensitive MI5 information and will make whatever they wish public.
