The character death at the end of Slow Horses season 4 gets a candid response from two of the show’s stars. The spy dramedy ended its fourth installment on Apple TV+ by going full circle in several ways. One of those was the death of a prominent Slow Horses cast member, which was teased in the premiere episode. It ended up unfolding very differently, with Marcus Longridge (Kadiff Kirwan) dying in a shootout at Slough House.
