'Slow Horses' Season 3 Sets A Holiday Release Date

After a long silence, Apple TV+ finally discloses when its comedic spy drama Slow Horses will return to streaming. Based on the Mick Herron series of spy novels Slough House, the British espionage series will return to the same spot in the calendar it occupied in 2022, with an early December premiere and a run of six episodes through the holiday season. The series, led by Gary Oldman (Tinker Tailor Soldier Spy), finished filming Season 3 almost a year ago in March 2023 and went directly into filming the already-greenlit Season 4. However, the long gap suggests fans will wait another year for episodes in 2024.

Unlike most British spy series, which involve either suave James Bond types or tough John Luther cops, Slow Horses (a pun on the "Slough House" name) was notable from the first for being about a misfit band of incompetents. This is where MI-5 puts the spies it cannot fire for one reason or another but who have failed in the field so severely they cannot be entrusted to do anything of import. Supposedly condemned to spend their lives paper-pushing, they're so bored that they catch the details that regular spies are too busy to notice.

Throughout the first two seasons, the Slow Horses have foiled an inside plot in MI-5 that attempted to pin their betrayals on their team and outed Russian sleeper agents within the agency. They also lost one of their own in Season 2, as Min Harper (Dustin Demri-Burns) was murdered halfway through Season 2.
