## Key points

- River collapses after touching a poisoned crowbar.
- The books indicate he survives Novichok poisoning.
- He may have a limited role in Season 7.

## Summary

The sixth season finale of *Slow Horses* leaves River Cartwright’s fate uncertain after he collapses from a neurotoxin, making his return in Season 7 look doubtful. The cliffhanger matters because the series has killed other major characters this season, while the show’s source material suggests River’s apparent death may be a misdirection.

The toxin was left on a crowbar by assassins Jim and Jane during an earlier break-in at David Cartwright’s home. In Mick Herron’s *Slough House*, River is poisoned with Novichok, hospitalised and eventually recovers; the article says this points to his survival, though he may be absent from much of Season 7. That could give more attention to agents including Shirley Dander and Roddy Ho, while Louisa Guy may also return full-time.
