2. Who is DSU Gemma Garland, and what does she know about DI Rachel Carey?

DSU Gemma Garland (Lia Williams) – the woman from MI5 who redacted the evidence in episode two – has been put on the Hannah Roberts case with DI Rachel Carey (Holliday Grainger). At first, it seems that Gemma wants to help Rachel, but soon heavily hints that she knows about Rachel’s affair with her old Counter-Terrorism boss, Danny Hart (Ben Miles). Gemma also starts to make the case difficult, keeping tight-lipped about why she redacted the CCTV footage and making Rachel question herself and the case. Is Gemma married to Danny? Is she setting up Shaun for murder? Is she making this case personal with Rachel?

Speaking of Danny…

3. What is Danny Hart’s involvement?

Danny Hart was noticeably absent from episode three, bar a scene where he stood in the surveillance room, overlooking Rachel’s failed attempt at finding Shaun in the Belgravia mansion. He refuses to answer Rachel’s appeals for help, despite the fact that they used to work (and sleep) together. The way he is distancing himself means that he must be involved with whatever the heck is going on. Also, Rachel later suspects Danny of manipulating another CCTV clip in one of his own recent cases. Is he in on to something with Gemma?
