Slow Horses season six finale ends on a brutal cliffhanger as the showrunner refuses to say who survives
Jack Lowden, whose spy River Cartwright is struck down by suspected Novichok poisoning in the Slow Horses finale, is widely rumoured to be the next James Bond.
Head writer Gaby Chiappe will not say whether the finale's victim pulls through: 'People survive it, but people also die from it.' The closing episode leaves one of Jackson Lamb's team in mortal danger and fans arguing over what comes next.
The episode delivers a shock death that cast members say left them in tears on set.
Ruth Bradley spent a week filming the finale's hardest scene: 'I was silently weeping.'
Jack Lowden is widely rumoured to be the next James Bond, fuelling talk of a departure from the show.
