If the first part was good, and gripping, then the second part is literally off the scale. The most gripping thing I've sat through since watching Line of Duty Series 3. Mercurio strikes again delivering shocks, twists, turns, and of course action. There is a relevance with this episode, which I found a little terrifying, the use of a van as a weapon, the apparent back biting and corruption that occurs at a high level, and the obvious favours for friends that goes on.
The complexity of relationship between David and the Home Secretary is what stands out most in this episode, I didn't see this panning out as it did. Everything I thought was going to happen now can't. It of course raises questions, number one being is the Home Secretary in danger, or is she the danger?
Superb production values, and a degree of acting that should gain awards, Keeley Hawes and Richard Madden are of course terrific, but a special mention for Gina McKee, I have a feeling she'll be a dark horse in this series.
Fabulous entertainment. 10/10
