This got off to a promising start and was enjoyably all the way through. By episode 6 I found myself checking how much time was left as they seemed to be no closer to finding out what was happening then they were in episode 1.
What your left with is more answers and the only crime they solved was not really with police work and was from 5 years ago.
I was disappointed with this and I would think twice before watching an ITV show before checking the reviews.
