Apple TV+’s hit spy thriller, Slow Horses, is returning to our screens this week. Starring Gary Oldman as the dishevelled boss of Slough House, Jackson Lamb, Kristen Scott Thomas as MI5’s deputy director Diana Taverner and Jack Lowden as River Cartwright, an ambitious but naive field agent, season five will drop on 24 September.

Each series of the critically acclaimed show is based on a different book in Mick Herron’s book series, Slough House, with the latest following the events of London Rules.

Both the books and the screen adaptation are a comedic take on the espionage genre – less James Bond and more The Thick of It. The series follows intelligence officers – dubbed “slow horses” by their peers – banished to desk work for bad behaviour. These misfit spies are prone to leaving top-secret documents on trains, chasing down the wrong bad guys, and accidentally embroiling themselves in government corruption.

The first novel, Slow Horses, was published in 2010 – but it didn’t make its way into the bestseller charts until years later. Herron has since penned eight more novels in the series, including the recently released Clown Town.

The winning formula of MI5 operations, high-profile assassinations, political conspiracies and dysfunctional agents has won the series a loyal fan base. Despite all the black humour, the spy plots are just as tight as Ian Fleming's or John Le Carre’s storylines. Whether you’re looking to dive into Slow Horses for the first time or have been keenly awaiting the new series, here’s everything you need to know – and where to watch season five.
