Man, that Season 5 finale hit hard, didn’t it? All the twists with Roddy and the chaos in London wrapped up nicely, but now everyone’s buzzing about what’s next for Jackson Lamb and the crew. Rumors keep popping up about Slow Horses Season 6 dropping as early as January 2026, especially with how fast this show moves. But digging into the details, things look a bit different. Let’s break down the potential release window, story hints, returning stars, and why this series keeps pulling viewers in.
Is Slow Horses Season 6 releasing in January 2026?
No official date from Apple yet, but the pattern points to an early 2026 release, most bets on fall like September or October.
Quick look at past seasons:
- Season 1 kicked off in April 2022
- Season 2 landed December 2022
- Season 3 hit late 2023
- Season 4 rolled out September/October 2024
- Season 5 dropped September/October 2025
Lately, it’s been that reliable fall slot. Outlets lean toward fall 2026. Some Reddit fans speculate a spring or summer shift (maybe May-June) based on production timelines, but nothing solid backs a January premiere. Early year drops aren’t the norm for this show anymore, and Apple usually spaces things out for awards buzz.
Slow Horses Season 6 Potential Plot
Big change here – Season 6 mashes up two novels: Joe Country (book 6) and Slough House (book 7). That’s a first for the adaptation.
Apple’s teaser description: The Slow Horses hit the road running while Diana Taverner drags them into a brutal game of payback and revenge.
Personal stakes crank up – old wounds reopen, betrayals sting deeper, and Lamb’s crew faces threats that hit close to home. Cast folks call it “high-octane,” shifting back to intense thrills after Season 5’s heavier comedy vibes.
Slow Horses Season 6 Expected Cast
Gary Oldman returns as the grumpy genius Jackson Lamb – no surprise there. The core gang should join him:
- Jack Lowden playing River Cartwright
- Kristin Scott Thomas as the scheming Diana Taverner
- Saskia Reeves as Catherine Standish
- Rosalind Eleazar as Louisa Guy
- Christopher Chung as Roddy Ho
- Aimee-Ffion Edwards as Shirley Dander
- Jonathan Pryce in his recurring spot
Hugo Weaving pops back for key moments. Behind the scenes, new writers step in, and Adam Randall directs (he handled Season 4).
