Preview — Slow Horses Season 4 Episode 1: Identity Theft
On Slow Horses Season 4 Episode 1, “Identity Theft,” we’re reunited with our favorite MI5 agents, along with Diana and the Park. Based on the photos from the premiere, it looks like we’ll be introduced to a couple of new characters as well.
The case of the season kicks off with a car bombing at a shopping center, and not so surprisingly, Slough House gets roped into the investigation.

Slow Horses Season 3 Episode 6, “Footprints,” ended with Catherine seemingly leaving Slough House after learning the truth behind what happened to Charles. While it’s unclear whether or not she’s still working there, we can still expect to see her this season, as the trailer and episodic photos reveal.
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. Thankfully, the series has already been renewed for a fifth season.
