Slow Horses Season 4 Release Date – When Is It Coming To Apple TV+?

Slow Horses Season 4 Release Date – When Is It Coming To Apple TV+?

Slow Horses is a thrilling television series that takes inspiration from the captivating Slough House series of novels by Mick Herron.

Premiering on Apple TV+ in April 2022, this spy thriller immediately grabbed the attention of audiences worldwide.

With three seasons available on Apple TV+, the show continues to captivate viewers with its intricate plotlines and intense performances.


And for those who have already watched both seasons of the Gary Oldman spy show, you'll have noticed that at the end of the third season finale, Apple TV+ premiered the trailer for the next season.

So now the big question is – Slow Horses Season 4 – when is it coming to Apple TV+??

Slow Horses Season 4 Release Date On Apple TV+

I can tell you up front that Apple TV+ has not yet given an official release date for Slow Horses season 4. And the bad news is that they are unlikely to until much later in 2024.

However, it looks like the streaming platform has found a rhythm when dropping new seasons so we're going to assume that new episodes will follow the same format.

On that basis, we will see season four in late November / early December 2024.

Adam Randall will direct season four, and as of January 2024, filming is more or less in the bag.

And the good news is that a FIFTH season has already been confirmed. That will be an adaptation of Herron's novel London Rules.

What Will Happen In Season 4?

Slow Horses season 4 is based on the fourth book in the series, Spook Street.

The show picks up in the aftermath of the season three finale with David Cartwright's declining mental health.

But given just how senior he was in M15 there's a real danger that he could start reveal top secrets as he goes senile.

However, while trying to figure out what to do, grandson River Cartwright has bigger problems when a bomb goes off in a busy shopping centre, killing forty innocent civilians.

Now that Diana Taverner is in the top spot, having successfully ousted Ingrid Tearney in season three, the pressure is on.

Can the agents of Slough House figure out who is behind this act of terror before the situation escalates?

Season Guide

So far, Apple has delivered 18 episodes of Slow Horses over three seasons.

The first season introduced us to the slow horses at Slough House, which is administrative purgatory for MI5 service rejects who have bungled their job but have not been sacked.

Heading them up is the legendary but deeply unlikeable veteran MI5 agent Jackson Lamb (Gary Oldman).

This team is colloquially known as the “Slow Horses.” Despite their past mistakes, the agents find themselves in a high-stakes situation when a young man is kidnapped, and his captors threaten to behead him.

Lamb’s team must overcome their past failures and work together to unravel the conspiracy behind the kidnapping.

As they dig deeper, they uncover a web of deception, betrayal, and political intrigue.

Season 2 Recap

Known as ‘Dead Lions', the series picks up from the end of the first season and sees Jackson Lamb and his team dealing with the aftermath of their previous mission.

A Russian sleeper agent in the heart of the British Intelligence community is activated, and it’s up to the Slow Horses to find and neutralise the threat.

We also learn more about the various characters and how they ended up at Slough House.

Lamb remains a hard-nosed leader, but his loyalty to his team becomes evident as he goes to great lengths to protect them.

The team navigates a maze of espionage, double-crosses, and hidden agendas, all while dealing with the disdain of the rest of the MI5 community.

The season culminates in a tense and dramatic finale, leaving the future of the Slow Horses uncertain.

In both seasons, Gary Oldman delivers a stellar performance, capturing the essence of a flawed yet brilliant spymaster.

Season 3 Recap

There is no disputing that Slow Horses knows how to maximise every minute of its six-episode seasons.

Devoid of waffle and unnecessary drama, the plots are tight and well executed, with entire stories wrapped up with little or no cliffhangers.

That said, characters keep evolving, as does an overriding plot regarding the assassination of the former head of MI5. But each season still encompasses its own story, making it an absolute pleasure to watch.

Slow Horses season 3 is based on the third book in the Mick Herron Slough House series, Real Tigers.

One of the slow horses is kidnapped by a former soldier bent on revenge, and the agents must steal valuable intel in exchange for their safety.

However, when the agents uncover a larger web of intrigue that involves the highest authorities in the Security Service, they suddenly find themselves slap bang in the middle of a conspiracy that threatens not only their future but MI5 itself.

Slow Horses Book In Order?

Mick Herron is a British mystery and thriller novelist and the author of the Slough House series. There are currently eight books in the series, which are…

We know that Slow Horses will run for at least five seasons, one based on each book in the order they were published.

But as of yet, nothing indicates that all eight books will be adapted.

Who Sings The Music In Slow Horses?

For those of you who are curious to know who sings the opening theme tune to Slow Horses, here are all the details…

It is called Strange Game, sung by Mick Jagger of The Rolling Stones, who co-wrote it with Daniel Pemberton.

During an BBC Radio interview, Jagger said that Daniel Pemberton approached him, but the track had no lyrics at the beginning. Jagger had already the book Slow Horses so it was an easy task as he knew the plot and the characters.

He said” “[Daniel Pemberton] said ‘Would you like to write the theme song for this?’ and sent me the track, but the track didn’t have melody. It just had a track and no words or anything.

“I was sort of intrigued because I’d actually read some of the books, and I like the books very much. So, I kind of knew what the scenario was, who the characters were, and what kind of characters they were. I kind of was ahead of the game.

“So, if it had been something I’d never heard of, I would have had to do a lot of homework. But I said, ‘Yeah, let me give it a go,’ and I just whipped off a couple of pages of lyrics straight away. Those were the verses.”

Will Smith Slow Horses Writer

Let me save you the trouble of googling it, the Slow Horses writer Will Smith, is not the Will Smith you're thinking of.

The Will Smith in question is actually William James Smith, an English comedian, screenwriter, novelist, actor and producer.

With writing and producing credits on hit shows such as Veep and The Thick Of It, it's easy to understand why the scripts and characters in Slow Horses are just so bloody good!
