He is missing from hospital when PJ and Ben discover a Mt Thomas man has been professionally killed.

But his every move is predicted. It seems the killer is always one step ahead. But when the killer himself is gunned down in front of PJ, the evidence swings around to implicate an insider, another cop. In an unimaginable act of betrayal PJ finally comes face to face with his nemesis—Maggie's killer and her own brother, Mick Doyle. When the smoke has cleared, PJ and Pat Doyle can finally scatter Maggie's ashes over the land she loved.
