“Slow Horses” starring  Gary Oldman returns for season four on September 4

Apple TV+ unveiled a first look at the upcoming fourth season of its widely acclaimed, BAFTA Award-winning espionage series “Slow Horses,” starring Academy Award winner Gary Oldman.

Adapted from “Spook Street,” the fourth novel in the CWA Gold Dagger Award-winning Mick Herron spy series “Slough House,” season four of “Slow Horses” will premiere globally on Wednesday, September 4 with the first two episodes, followed by one new episode weekly, every Wednesday through October 2, on Apple TV+.

“Slow Horses” is a darkly humorous espionage drama that follows a dysfunctional team of British intelligence agents who serve in an MI5 dumping ground department known unaffectionately as Slough House. Season four opens with a bombing that detonates personal secrets, rocking Slough House’s already unstable foundations.
