Interesting premise, fine performances. I have no idea why ITV cancelled this series after only 4 episodes, and on a cliffhanger, at that. The user ratings for this are all between 7 and 8. The show never missed a beat, was entirely plausible and the audience became invested in the characters, which made the last, unresolved, missing person especially heartbreaking. This was a missed opportunity ITV. I give this series an 8 (great) out of 10. [Police Procedural with a twist]. Just a side note for Whovians, two of the principal players were Mickey Smith (2005-2010) and River Song (2008-2017).
