The Justice system struggles to find answers to Lyn's disappearance.

Before the first coronial inquest, police tap phones in the lead-up to digging in a relatively small area around the swimming pool at Bayview, where they find a woman's cardigan. The crime scene officer on that dig describes what he believed were stab marks in the garment. He suspects Lyn's remains are still on the block - and may have been narrowly missed because the dig was restricted for budgetary reasons. The coronial inquests get under way and they are bad for Chris - but the system fails Lyn and her family again.
