Rob, unmoored by Cassie鈥檚 absence, is increasingly obsessed with Jonathan Devlin, convinced he and his childhood friend Cathal Mills may be dangerous paedophiles.

Meanwhile, Jonathan has sent his daughters Rosalind and Jessica away from Dublin. Rob tracks Rosalind down to a dingy caravan park. Soon the extent of Rosalind鈥檚 disturbed behaviour emerges, and Rob feels he can save the girl. Meanwhile, Cassie starts to back away from Operation Vestal, spending time with Frank as he schools her in the art of being Lexie.

Rob realizes time is running out on the investigation and decides the only way to fully remember what happened that day is to spend the night alone in the woods, totally immersed in that strange world...
