Episode 3 (E03)

As Katy is finally laid to rest, all of Knocknaree comes out for the funeral. The public and media pressure to find Katy’s killer is intense, and Superintendent O’Kelly is concerned that all lines of inquiry have led to naught. Rob, however, is increasingly certain that his memories are leading him to the truth. Just as it looks like the trail has run cold, Dr Mark Hanley, the academic head of the archaeological dig where Katy was found, is arrested in the woods while carrying out a strange ritual. Meanwhile, Cassie gets a frantic dawn phone call from Frank, following the trail of corrupt land deals along the path of the planned motorway. And in Wicklow, in the ruined shell of a famine cottage, Cassie comes face to face with her worst nightmare. (BBC)
