Slow Horses season 4: preview

Featuring new antagonists both within the MI5 and beyond Diana Taverner's scope, season 4 feels like a reset for Slow Horses, not that you'd tell from a glance at Jackson Lamb's grease-matted trenchcoat. 

Hugo Weaving joins the cast as big bad Frank Harkness, the head of an "an assassination squad", James Callis portrays Claude Whelan, Taverner's second-in-command, and Emma Flyte enters as MI5 agent Ruth Bradley, who's drawn the short straw of straitjacketing Lamb.

The series, which is based on Mick Herron's novel Spook Street, promises to reintroduce the jeopardy that characterized the first two seasons and went missing in season 3, which felt almost entirely self-contained. 

It's been confirmed that one of the slow horses will meet their death, and with David Cartwright succumbing to dementia, Catherine Standish will get closer to exposing the dirty secret that Lamb and his erstwhile superior have been sitting on, though it's likely to be something of a Pandora's Box. And she's not the only one on his tail.

Watch Slow Horses season 4 from abroad with a VPN

Apple TV+ is now available in over 100 countries worldwide. But if you find away from home you might find yourself geo-blocked from your usual account.

A Virtual Private Network (VPN) helps you get around this obstacle. It creates a private connection between your device and the internet, allowing you to appear to be in your home country. There are lots of VPNs to choose from, but we think NordVPN is currently the very best VPN for streaming.
