What's 'Slow Horses' about again?

For those of you still out of the know, Slow Horses is a dark comedy espionage series that follows a group of disgraced MI5 agents exiled to Slough House – essentially the intelligence community's rubber room. Leading this band of misfits is Captain Crank, Jackson Lamb, played by the incomparable Gary Oldman.

What will 'Slow Horses' season 5 be about?

This season, things go from odd to downright bizarre. The official description teases suspicion around resident tech guru Roddy Ho and his new ever-so-glam lady-friend. A string of increasingly strange events unfolds across London, and it's up to the Slow Horses to connect the dots. Like Lamb says, "In the world of espionage, the London Rules — cover your back — always apply."
