As Katy is finally laid to rest, Rob continues to be haunted by memories of the past and Jonathan Devlin and his friends' disturbing presence in the woods on the fateful day Peter and Jamie disappeared. 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. Cassie receives a frantic dawn phone call from Frank, who is in Wicklow following the trail of corrupt land deals along the path of the planned motorway.
