This felt like a bit of a deviation away from the main story somehow, it's more focussed on the personal lives of Cormoran and Robin.
Perhaps the most accomplished episode of Strike I've seen, I thought this was absolutely terrific, I loved it, and that was largely due to the acting of Holliday Grainger, she was superb here. She was awesome as Becca, it took a few minutes to realise it was her, the scene with her husband was terrific.
Will we get more from Anette Badland? That seemed like such a miniscule part for her.
I thought it was tremendous, 9/10.
