In the ancient Singing Gorge, where sound travels in mysterious ways and sacred ceremonies have been performed for millennia, Special Investigator Odysseus "Odie" Kalaris is called to investigate when ethnomusicologist Dr. Simon Parker is found dead at the base of a cliff.

What begins as a possible accidental fall evolves into something far more sinister, revealing connections between sacred ceremonial recordings and powerful academic, commercial, and political interests. When Odie discovers Parker's recording equipment is missing and evidence of a struggle at the cliff edge, he must navigate both the cultural boundaries surrounding sacred knowledge and the complex web of deception spun by those who would exploit it.

As the investigation intensifies, Odie uncovers links between Parker's death and a sophisticated operation to extract valuable ceremonial sounds for commercial film industry use. With time running out and those responsible becoming increasingly desperate, each revelation tests Odie's tracking abilities and puts his understanding of both his mother's Gija heritage and his father's Greek traditions to the ultimate test.

The vast Kimberley landscape conceals deadly motives where academic ambition, commercial greed, and cultural exploitation intersect. But in a country where sound itself carries ancestral knowledge, some tracks lead to secrets that will kill to stay buried.

Odie must rely on traditional tracking skills and cultural understanding to read the signs before more lives are lost, all while confronting forces that view sacred knowledge only as a resource to be exploited.
