Based on Mick Herron’s Slough House novels, Slow Horses is the first book in the series focusing on a group of dysfunctional MI5 agents dumped in a small office in London hoping to restore their names by defending Britain. The team of misfits is led by Jackson Lamb, played by the award-winning Gary Oldman, who continues to make sure his recruits know they’ve not found themselves in his office for good reasons.

Soon after River Cartwright, played by Jack Lowden, joins the competent crew at Slough House as their latest recruit, the team find themselves intertwined in the middle of a dangerous hostage situation that forces them to step out from behind the paperwork and back into a sinister mission of espionage – with such a compelling story, it's no wonder why it's one of the best Apple TV Plus shows.  

The show has been confirmed for season 5 after the hit spy series set a new record for Apple TV Plus, but while we wait, here are six shows to watch if you like Slow Horses and want to indulge in more tales of British spies.

London Spy

Watch On

A crime drama made by the BBC, London Spy stars James Bond veteran Ben Whishaw as Danny Holt, a young man entangled in mystery after his MI6 code genius and spy lover is murdered. Plunged into a thrilling tale of espionage, London Spy, much like Slow Horses, is a contemporary tale set to the dark, gritty backdrop of England’s capital city whilst also staying true to some of the platitudes of the traditional spy drama genre.

Danny himself is an ordinary man with no knowledge of what it takes to work in the Secret Intelligence Service, yet he’s navigated by mentor, Scottie, played by Jim Broadbent, to help him find some truth from the tragic loss of his partner. Intricate, cloaked in mystery, but super gripping. 

Available to stream on Xumo Play in the US. The series is only available to buy on Apple TV in the UK and Australia. 

Killing Eve

Eve Polastri, played by Sandra Oh, is a British intelligence operative tasked with finding and capturing trained assassin, Villanelle, played by Jodie Comer, of which nothing about the mission is simple.

Killing Eve spans four seasons – the show ended with Killing Eve season 4 but enjoyed a renaissance on Netflix when it was released on the platform in April – of gory, complex, and inexplicable attraction in a world where the lines between good and bad lay continually blurred.

The Little Drummer Girl comes from his 1983 novel of the same name where an aspiring English actress is brought in by Mossad to infiltrate a dangerous terrorist cell plotting crimes across Europe. 

Florence Pugh plays double agent Charlie aka Charmian is recruited by Gadi Becker, played by Alexander Skarsgård, to impersonate a suspected bomber’s girlfriend in order to investigate the true criminals.

Ex-British soldier and night manager of a luxurious Cairo hotel, Jonathan Pine (Hiddleston), is recruited as a secret operative to infiltrate a secret arms dealer’s inner circle. 

A great tale of espionage with similar dark nature and British prowess of Slow Horses, The Night Manager sees Pine embark on a mission that requires him to harness all the skills he’s ever learnt in his years of service to successfully complete an incredibly dangerous mission in order to protect the world as we know it.

Spooks, a stalwart name of British spy shows, is also full of cast names that have continued in great success from Succession’s Matthew Macfadyen to Bodyguard’s Keeley Hawes to award-winning Selma and Nightingale’s David Oyelowo.
