Stephen Hunter-Dunn

Stephen Hunter-Dunn occupies the upper reaches of the security establishment in Bodyguard's world of counter-terrorism command and Whitehall politics. Composed and institutionally fluent, he moves through briefings and closed-door meetings with the practiced calm of a man used to managing crises from a safe distance, more concerned with process and position than with the people beneath him.

Stuart Bowman plays him with the dry, unbothered authority of someone who has survived many administrations, letting small shifts in tone do the work of exposing where real power sits. In a thriller built on paranoia and shifting loyalties, his stillness is unsettling precisely because it never explains itself.
