If you enjoyed seasons 1 and 2 of the Apple TV+ series Slow Horses, you'll be thrilled to know the premiere date for season 3 is drawing near – and it's sooner than originally expected.
Though we try to stay as objective as possible around here, it's easily one of the best new British TV shows of the last 10 years, and we're excited to see what's in store for the new season.
What's Slow Horses About?
Slow Horses is based on Mick Herron's CWA Gold Dagger-winning Slough House series, and it follows the activities of a group of misfit spies who are much more talented than their career trajectories might imply.
Led by agent Jackson Lamb, the operatives at Slough House have each done something really, really bad to derail their otherwise promising careers. As a result, they're parked in a sort of purgatory, assigned to work on non-essential tasks until they reach retirement age. The only problem? Trouble seems to have a way of finding them.
What's Happening in Season 3 of Slow Horses?
Season 3 is adapted from Real Tigers, the third novel in the Slough House series. When a romantic liaison in Istanbul threatens to expose a buried MI5 secret in London, Jackson Lamb and his teams are dragged into something much bigger than themselves. They uncover a web of intrigue that threatens to bring down all of MI5.
Though Apple's own official description doesn't mention it, the book's blurb mentions the kidnapping of a Slough House operative. Because it's one of their own, the agents are prepared to do just about anything to get their colleague back safely – including breaching security at the MI5 headquarters and stealing valuable intel to exchange. There's always some variation between book and TV, but it's interesting to read the book blurbs ahead of time to get a little extra insight into what might be ahead.
Season 3 will be comprised of six episodes.
