Episode #1.2

Saara discovers a piece of encrypted text hidden in the malware, being new to the place, she's not confined to department tribalism.

I enjoyed the first episode, I really enjoyed this second episode, the characters have definitely developed here, and the story moved on somewhat too.

Saara has definitely grown on me somewhat, I'm struggling a little with her mind library scenes somewhat, they worked on Sherlock, not so much here, but that's a minor point.

A point off for Saara's stale colleagues, slightly lazily written, apart from one, Mark Rylance was fantastic here, and his scenes with Saara at The old GCHQ were cracking, and gave us an insight into both characters.

Channel four dramas always seem to have the ability to make you think and question, this does, and who knows, this glimpse of the future could well be reality.

Very good, 8/10.
