Story and Source Material
Season 6 draws from Joe Country and Slough House, the sixth and seventh novels in Mick Herron’s Slough House series. Apple TV’s official summary says the season follows the Slow Horses as Diana Taverner draws them all into an urgent and deadly struggle for life and vengeance.
Joe Country follows Catherine Standish falling back into drinking, Louisa Guy returning to thoughts of a lost love, and a new member of the team, Lech Wicinski, trying to find out who ruined his career. Meanwhile, Diana Taverner’s hold on her post at Regent’s Park grows weak, and she may need help from an old adversary to keep it. Slough House, the second book folded into the season, is set against the fallout of Brexit. The Slow Horses have been dropped from official MI5 records, and members of Jackson Lamb’s team start dying in strange, frequent ways, leaving them to wonder if they are being hunted.
Season 5 centered on Roddy Ho and a companion who used him to help her team carry out terror attacks across London. Many viewers called it the most amusing season yet. Season 6 marks a clear change in mood, with past and present Slow Horses fighting to stay alive as hits are placed on them.
