Slow Horses Season 6 follows targeted attacks on MI5 agents

The sixth season of the Apple TV+ espionage series ‘Slow Horses’ introduces a new threat targeting the disgraced MI5 agents of Slough House. Following the funeral of David Cartwright, the narrative shifts toward a deadly pattern where former agents are being systematically hunted by assassins.

One such victim is Struan Loy, a former resident of Slough House. The season explores the escalating danger faced by the group, as they transition from being mere bureaucratic outcasts to active targets of an external force. Amidst these developments, the character River Cartwright remains a central figure, surviving various life-threatening encounters and complex personal revelations, including the discovery of his biological father.
