Slow Horses Season 6 finale leaves River Cartwright's fate uncertain

The sixth season of the Apple TV+ spy thriller ‘Slow Horses’ concluded with a major cliffhanger involving the character River Cartwright, played by Jack Lowden. In the final moments, Cartwright appears to be poisoned by a nerve agent, likely Novichok, after coming into contact with a contaminated crowbar at his grandfather's house. The episode ends with him collapsing, leaving his survival in question.

The season was marked by significant character deaths, including Struan Loy, JK Coe, and Emma Flyte, as a Russian hit squad targeted the Slough House unit. The finale also featured the return of Sid Baker, played by Olivia Cooke, though her reunion with Cartwright was cut short by the poisoning incident.

Speculation regarding the cliffhanger has been fueled by rumors that Jack Lowden is a candidate for the next James Bond role. While the character survives the poisoning in Mick Herron’s original novels, the series has not yet confirmed if the show will follow the source material or if the character will be written out. A seventh season has already been confirmed, with a potential return in autumn 2027.
