Probably the best spy show on air right now, Slow Horses delivers knockout action and plotlines that keep you hooked.
Adapted from Mick Herron’s Slough House books, Slow Horses is a masterclass in dark humor and espionage.
The series focuses on a group of MI5 misfits shuffled off to Slough House, a dingy outpost for the “rejects” of British intelligence.
Led by the gloriously grumpy Jackson Lamb (Gary Oldman in top form), these “failed” agents — like River Cartwright, a legacy spy who sometimes makes you wonder what school he went to — are stuck with dead-end assignments.
But when things go sideways, it’s these underdogs who get the call.
With wit as sharp as its twists, Slow Horses shows that being at the bottom doesn’t mean you can’t save the day.
