‘Slow Horses’ Season 6 Episode 4 Release Date, Time, Where to Watch and Preview
The fourth episode of the sixth season of ‘Slow Horses’ is titled “Lost and Found” and is set to arrive on Wednesday, October 7. Apple TV lists the episode alongside the rest of a weekly schedule that began with the season premiere on September 16. The spy drama has kept to that steady rhythm since its return.
With the season well into a compact run of six episodes, viewers are looking for the timing, the platform and some sense of what the next chapter holds. The season adapts two novels from Mick Herron’s series, which makes it a slight change from earlier instalments. This guide gathers what is publicly known about the fourth episode of the sixth season of ‘Slow Horses’ ahead of its arrival.
‘Slow Horses’ Release Date and Episode Schedule
Apple releases a new episode every Wednesday, and the season wraps with its finale on October 21. The fourth episode lands on October 7, following “Resurrection” on September 30. “Sayonara” is next on October 14, and the season closes with “Judgement Day.”
The season adapts Joe Country and Slough House, the sixth and seventh books in Mick Herron’s series. That means the story is drawing on two novels across a single short season, and the pacing reflects it. Each weekly installment carries a sizable share of the plot.
Apple has already confirmed a seventh season based on the novel Bad Actors, and an eighth season is also in the works. The long term future of the series looks secure, which gives this season room to raise the stakes for its central characters.
‘Slow Horses’ Release Time for the Fourth Episode
Apple only officially lists the calendar date, but it is a pattern for the company to release episodes the night before. For that reason, viewers who want to watch as soon as possible should look for the episode in the evening of Tuesday, October 6, in the United States.
The premiere became available at 9 p.m. ET on the night before its listed date, according to Just Jared. Viewers in other regions will need to convert from Eastern Time to their own local clocks. None of the reporting reviewed singles out the fourth episode for a different window, so the same late evening timing is the safest expectation.
The second episode, “Daddy Issues,” followed on September 23, and the third, “Resurrection,” on September 30. Those dates match the official Wednesday schedule, which suggests that the early drop is a courtesy to subscribers and not a change to the calendar.
Where to Watch ‘Slow Horses’ on Apple TV
The sixth season premiered globally on Apple TV on September 16, and new episodes continue weekly until October 21. There is no broadcast alternative, so a subscription to the streaming service is the way in. Tom’s Guide notes that a seven day free trial is available for new subscribers.
Earlier seasons of the series have also streamed on the same platform, which makes it simple to catch up before the new episodes arrive. The fourth season, for example, began on Apple TV Plus in September 2024 and ran for six episodes. Anyone starting late has a manageable amount of ground to cover.
The series has also built a strong awards record. It won three awards at the 2026 Emmys, and an additional renewal was announced one day later. That recognition helps explain why the weekly release has become appointment viewing for its audience.
Preview of the Fourth Episode of ‘Slow Horses’
According to the synopsis listed by Rotten Tomatoes, Lamb tries to work out who Frank is working for, while Sid, River and Coe do everything they can to evade the hit squad. That pairs an investigation at Slough House with a chase in the field. It also keeps the pressure on characters who have already been forced from their routines.
The wider story centers on a pair of ruthless killers. Jackson Lamb, played by Gary Oldman, and River Cartwright, played by Jack Lowden, find themselves and several former slow horses hunted by two assassins played by Kyle Soller and MyAnna Buring. Hugo Weaving is also reprising his earlier role in the new season. The return of Olivia Cooke as Sid Baker, whom nobody had seen since the first season, gives the chase added weight.
Critics have responded warmly overall, though not unanimously. One review on Rotten Tomatoes calls the season the best yet, while another gives a more measured three out of five and suggests the show may have run its course. With the hunt tightening around Sid, River and Coe, do you think Lamb can uncover who is behind Frank in time to protect them in “Lost and Found”?
