Given their relationship with the locals and their general enthusiasm level, Doherty and Byrne had been assigned to go through a bazillion hours of closed-circuit TV footage, looking for regular unexplained visitors to Glenskehy, but the cameras hadn’t been positioned with this in mind and the best they could come up with was that they were fairly sure no one had driven into or out of Glenskehy by a direct route between ten and two on the night of the murder. This made Sam start talking about the housemates again, which made Frank point out the multiple ways someone could have got to Glenskehy without being picked up on CCTV, which made Byrne get snippy about suits who swanned down from Dublin and wasted everyone’s time with pointless busywork. I got the sense that the incident room was blanketed by a dense, electric cloud of dead ends and turf wars and that nasty sinking feeling.
