A First Look at ‘Slow Horses’ Season 4
Slow Horses Season 4 finds our favorite slow horses, along with the Park, investigating a bombing in London. The teaser trailer footage features Lamb saying, “one of my team just died,” in response to being asked if he’s going to shower. Lamb, never change.
Elsewhere this season, River’s grandfather is starting to become forgetful and paranoid, prompting River to consider what kind of retirement homes exist for spies.
And let’s not forget that we still don’t know what Louisa plans to do with the diamond she stole after the rooftop shootout on Slow Horses Season 2 Episode 6, “Old Scores.”

I’m sure the slow horses will find themselves in all sorts of trouble this season, and it’s going to be a lot of fun to watch.
Slow Horses Season 4 premieres with one episode on Wednesday, September 4, on Apple TV+. New episodes will stream weekly through the season finale on October 9. This season is adapted from Spook Street, the fourth novel in the CWA Gold Dagger Award-winning Mick Herron series.
Thankfully, the series has already been renewed for a fifth season, which will follow the fifth novel, London Rules.
