Synopsis

A new leader emerged in Section D with Harry Pearce on gardening leave: Erin Watts. She brought Calum Reed with her, reshaping the team's dynamic. Meanwhile, Harry Pearce secured his reinstatement after winning his MI5 employment tribunal and soon returned to the heart of the action. But the return of normalcy was short-lived. The discovery of retired spy Max Witt murdered in Berlin, a colleague of Harry’s from their Cold War days, unleashed a torrent of long-buried secrets.
