If you've missed Jackson Lamb's piercing putdowns, you'll be pleased to hear that the irascible spymaster is back in full force, leading his band of disgraced MI5 agents into yet another brilliantly tangled mess in season 5 of Slow Horses.
Based on Mick Herron’s acclaimed Slough House novels, Slow Horses is not your usual spy thriller; it peels back the curtain on the unglamorous side of spy work. Rather than sleek gadgets and high-speed chases, the show dives into the everyday grind, the messy mistakes and the flawed agents who’ve been shoved to the sidelines. It’s all about trying to survive in the shadows of the intelligence world.
Thenew series is set to keep that same vibe going, with tight, character-driven stories that will keep us all hooked.
