Cottan
SPOILERS (For anyone who hasn't seen episode 5)
So what's Cottan's motive for shooting dead Lindsay Denton? He looked pretty desperate to stop her sending that ss of the list. My guess is that only a man who's name is on the list would act like that.
Either that or someone on the list has something pretty big on Cottan that he needs kept under wraps.
When he was watching the interview with Fairbank he seemed really agitated until he saw it going nowhere.
So that begs the question, is Matthew Cottan his real name?
Or who is on the list that he is working for?
hmmmmm...
