Apple TV+'s Slow Horses closed season 6 with the apparent death of River Cartwright, following Emma Flyte's killing by Frank Harkness earlier in the episode. Showrunner Gaby Chiappe told Gold Derby that a poisoned crowbar, seeded in a scene from episode 2, suggests River was exposed to a Novichok-style nerve agent. Apple also released a first teaser trailer for season 7 immediately after the finale.
