Will There Be Slow Horses Season 5?

Yes, Slow Horses has already been renewed for season 5. The news came way back in January 2024, just after season 3 ended in December. In fact, even though season 4 is only just arriving on Apple TV, filming for season 5 took place in March 2024. Apple is clearly aware it’s got a good thing going.

What Will Happen?

Slow Horses season 5 will be based on the fifth book in Mick Herron’s Slough House series of espionage novels, London Rules. Apple TV has already released a logline: ‘Everyone is suspicious when resident tech nerd Roddy Ho has a glamorous new girlfriend, but when a series of increasingly bizarre events occur across the city, it falls to the slow horses to work out how everything is connected. After all, Jackson Lamb knows that in the world of espionage, “London Rules” should always apply.’

When Will It Be Released?

We anticipate Slow Horses season 5 will start streaming on Apple TV in the first half of 2025.

What Is Slow Horses About?

Slow Horses is a popular Apple TV series following a team of British intelligence agents who have all committed career-ending mistakes. As a result, they are resigned to Slough House and nicknamed the ‘slow horses’, damned to dull, paper-pushing tasks while enduring verbal abuse from their miserable boss, Jackson Lamb (Gary Oldman). However, the slow horses still manage to get involved with investigating schemes that endanger Britain, and each season focuses on a different plot.

Is Slow Horses Based On A Book?

Yes, Apple TV’s Slow Horses is based on Mick Herron’s Slough House series of espionage novels. Each season adapts the next novel, and the novel title is the season’s subtitle. Herron’s series of novels is as follows:

1. Slow Horses (2010)
2. Dead Lions (2013)
3. Real Tigers (2016)
4. Spook Street (2017)
5. London Rules (2018)
6. Joe Country (2019)
7. Slough House (2021)
8. Bad Actors (2022)

Herron has also written three novellas in the series: The List (2015), which is set between books two and three; The Marylebone Drop (2018), set between books five and six; and The Catch (2020), set between books six and seven. No news just yet on when we can expect the series’ ninth instalment, but it is widely believed Herron will publish one or two more books before he is finished with the series.

Where Is It Filmed?

Slow Horses is mainly filmed in London, where the series is also set. ‘We’ve always tried to have our anchor [be Slough House], and just be true to the geography of the original writing,’ Ian Pollington, Slow Horses’ location manager, recently told The Evening Standard. ‘I think it would be easy to just put them [the cast] on a low loader and stick them off out on the A13 and say, well, they’re in the car and that’s fine. It’s not so easy to put them in a car on the Old Street roundabout and drive them through London. But it’s worth doing and it’s worth it [for viewers to] say, “actually, that all sort of makes sense, because I live in Central London and there’s logic to it”. We haven’t taken the easy way out.’

Much of Slow Horses is filmed in Islington and Tower Hamlets boroughs of London, as well as Marylebone and King’s Cross. However, some scenes are filmed just outside London in Hertfordshire.

Where Is Slough House?

In Herron’s books, Slough House is located above a Chinese restaurant on Aldersgate Street, which runs along the west side of the Barbican estate. The Apple TV series is also filmed here – though it was no easy feat. ‘We looked at that location and thought, “this isn’t really practical”,’ says Pollington. ‘It’s on a busy junction, it’s on a road, you’ve got the [Barbican] station pouring out […]. We looked at other places. We looked further down, into Hackney and Tower Hamlets, but actually we came back, after engaging with the local community and with the Barbican Estate. […] We made that decision to be true to the book and shoot on location.’ Thanks to road closures and community engagement, the TV series is true to the book.
