Slow Horses: Catherine's Dangerous Secret Revealed

Slow Horses season six on Apple TV has initiated a perilous journey for Catherine Standish following the revelation of Jackson Lamb's decades-old secret. As revealed in the first episode, Catherine discovered that Jackson, along with David Cartwright, murdered Charles Partner in the past to prevent embarrassment from his sale of secrets to Russia.

This truth, hidden from Catherine for years as she served as Charles' assistant, was inadvertently revealed by Diana Taverner, MI5's Second Desk. Actress Saskia Reeves stated that this revelation places Catherine on a "dangerous journey" as she grapples with the betrayal. The current season promises a return to earlier dramatic themes, with the Slough House agents becoming targets for assassins.

Reflecting on the show's appeal, Reeves noted its "very British" approach to spy dramas, highlighting the inherent messiness and chaos that resonates with audiences. She also praised series lead Gary Oldman for his collaborative spirit, which fosters a sense of improvisation among the cast despite thorough preparation.
