Made a career ending mistake at MI5? Then it's off to Slough House, a dumping ground for agents who have epically messed up. Known as the Slow Horses the team are led by Jackson lamb and find themselves in the middle of a huge operation gone wrong. A truly superb spy thriller series from Apple TV+.

I'm still amazed by the quality of tv shows that Apple TV+ manages to churn out. They may not be dropping them at the speed of their competitors but Slow Horses is just another example of an incredible series that will grip you from the second it starts.

Slow Horses opens with an MI5 operation at a UK airport. River Cartwright (Jack Lowden) is the agent in charge and needs to locate a potential terrorist who plans to set off a bomb.

When things don't go to plan, Cartwright is relegated to Slough House. Based in London, this is a dumping ground department for members of the intelligence service who've screwed up.

It's a small team of agents who've all made stupid mistakes and paid the price. Left a service file on a train, blown a surveillance, or become drunkenly unreliable? Then it's off to Slough House.

Nicknamed the the Slow Horses, the team is run by Jackson Lamb (Gary Oldman) who assigns the most menial tasks to his crew of misfits.

Everything about the job is grim. The building is awful, the job is awful and the boss is awful but that all changes when a young man is abducted and his kidnappers threaten to behead him live on the Internet.

Beginning with surveillance on a right-wing has been journalist, Cartwright believes that he holds the key to finding the victim and the abductors. Seeing an opportunity to redeem himself, if he can figure it all out he might just make it back to MI5.

As the clock ticks on the execution, everything starts to go wrong and led by Jackson Lamb, the team make the shocking discovery that they are not just the poor relatives, but the fall guys for an operation gone badly wrong where everyone involved has their own agenda.

Will the Slow Horses attempt to rescue Hassan Ahmed or will they save their skin and get out of dodge?

Is Slow Horses, Worth Watching?

Without a shadow of a doubt, Slow Horses is one of the best drama's currently streaming.

Based on the 2010 novel of the same name by Mick Herron, this is a spy thriller series with a difference.

Instead of the usual slick, fast action agents that we normally see, what we get with Slow Horses is the polar opposite. Agents who have made career ending mistakes, with little recognised skill and beaten down by years of having had to work with Lamb.

Gary Oldman (Darkest Hour) as Jackson Lamb is simply genius. A former spy, his outward disgusting mannerisms just about conceal the fact that he not only is he still on top of his game but that he actually cares about the rest of his team.

He is matched in star power by Kristin Scott-Thomas as Diana Taverner the Deputy Director-General of MI5. Their scenes together are effortless and as the show slowly peels back the layers, it's their battle with each other that becomes the most engaging.

This isn't all action, it's a wonderfully created slow burn television series that reels you in with each episode leaving you desperate to figure out how the whole show will unfold.

How Many Episodes Of Slow Horses, Apple TV?

This is where things start to get interesting. Slow Horses was given a straight to series order by Apple TV+ in October 2019 consisting of two sets of six episodes.

Whether this means two six-episode seasons, or one season in two parts, we don't quite know. The first six episodes are based on Mick Herron's first book, Slow Horses

The following six episodes are based on the based on the sequel and follow-up novel, Dead Lions.

So we won't be getting all 12 episodes in one go. In fact, the second season is still in production with no announcement from Apple TV+ about when it will drop on the streaming service.

  1. After bingewatching the brilliant ‘Slow Horses’ I am reading Mick Herron’s books from the beginning: superlative! Not to page-turn, the writing is to be savoured. Thoroughly enjoyable.
