Series 10 Filming & Behind the Scenes

[Forever Secret]

I agree, but I think there will be a story arc, it could work as long as the story arc isn't too overly complex and each episode has a strong story line it should be alright, 8 is just the right amount, with 6 it'll be more of a challenge
Perhaps now it can be safely said the investigation into Harry will be this Series running storyline, but I think it would just settle on one event in his past rather than just bits and pieces of his past operations ect
