In Broome's tourist-perfect marina, where million-dollar boats promise wilderness adventures to wealthy visitors, Special Investigator Odysseus "Odie" Kalaris is called to examine what appears to be a robbery gone wrong.

What begins as a straightforward marina murder evolves into something far more sinister, revealing connections between luxury tourism and a sophisticated fraud network targeting elderly investors. When Odie's tracking skills expose crime scene staging, he must navigate both the predatory undercurrents of seasonal tourism and the complex relationships that bind Broome's tight-knit business community.

As regulatory investigations close in, Odie uncovers links between victim Jack Lawson and systematic exploitation spanning years of apparently legitimate operations. With multiple suspects harbouring desperate motives, each revelation tests Odie's abilities while putting his understanding of both his mother's Gija heritage and his father's Greek analytical traditions to the ultimate test.

The pristine Kimberley coastline conceals financial desperation and betrayal, where community trust becomes a weapon for manipulation. But in a country where ancient tides wash away yesterday's crimes while bringing fresh opportunities for exploitation, some deceptions run deeper than the harbour's dark waters.

Odie must rely on traditional tracking knowledge to read the human signs before desperation drives someone beyond all moral boundaries, all while confronting forces that view vulnerable communities only as resources to be exploited.
