Really enjoyed this first episode, although obviously harrowing at times.
I was confused by two of the main characters looking so alike (Morgan and Eason) but wonder if they have done that deliberately because so far they have only gone on racial profiling to find the perpetrator (if the face fits, you're a suspect) so it's ripe for a case of mistaken identity?
I'm assuming that Martin Clunes comes up trumps and solves the case but for now my money is on Dave, whose only job this episode was to hold a door open, but it was worthy of a lingering camera shot...
