It starts off as a police procedural. DI Rachel Carey has problems adhering to the rules of interrogation. She denies Emery a phone call, questions him in a police cell and not the interrogation room. She only has 24 hours to hold him and then Emery has to be charged or be released.
It does look like that Emery has psychological issues as he gets easily provoked.
The problem for Carey is the CCTV evidence is withdrawn due to pressure by security services. Emery has already been in custody for 19 hours hence the urgency. That is until Carey realises Emery could be released on police bail, pending further enquiries and so the clock is stopped. Therefore no urgency at all!
The appearance of a mysterious woman from the security service cranks this up by a gear. Emery wants answers and goes looking for Hannah Roberts by breaking into her flat. There is another intruder already there.
Carey knows there is something more going on in all this. She tracks Emery's movements through a police surveillance room and discovers you cannot believe everything you see.
Ron Perlman is credited in this episode and I had a fair idea when he would turn up. This episode really had a change of pace and a few surprises. I really did not expect it to happen so soon.
