Get ready to return to Slough House: Slow Horses season 4 finally has a release date. Gary Oldman will return as Jackson Lamb this September for the next installment in Apple TV Plus' espionage thriller and the streamer has released a first look at the new season, too, which you can see below.
The fourth season of the show will begin with a double episode premiere on September 4, with the rest of the episodes releasing weekly through to October 2 – meaning it's a six-part installment, just like seasons 1 to 3.
