Get in, losers. We’re going to Slough House to reunite with our favorite misfit MI5 agents in Slow Horses Season 4.

Will Smith’s critically-acclaimed Apple TV+ series returns with an adaptation of Spook Street, the fourth novel in Mick Herron beloved book series, and you won’t want to miss a minute of the mayhem.

Per Apple TV’s official synopsis, Season 4 of the addicting espionage drama “opens with a bombing that detonates personal secrets, rocking Slough House’s already unstable foundations.” If you’re in need of a detailed Slow Horses Season 3 finale recap before you sink your teeth into Season 4 like Lamb (Gary Oldman) devouring an ice cream cone, Decider’s got you covered.

Here’s everything to know about the return of Apple TV+’s critically acclaimed series.

Slow Horses Season 4 premieres with one episode Wednesday, September 4 on Apple TV+.

In keeping with tradition, like the first three seasons of Slow Horses, Season 4 will consist of six episodes.

As noted above, new episodes of Slow Horses Season 4 will premiere weekly on Wednesdays until the finale. That said, Apple TV+ often releases new episodes at 8:00 or 9:00 p.m. ET the night ahead of designated premiere dates, so if you’re extra eager to watch, keep your eyes peeled for new episodes on Tuesday nights.

If it’s Wednesday and you don’t see a new episode of Slow Horses on Apple TV+, don’t panic! Try refreshing your browser or app. Sometimes platforms take a few moments to load new content.
