When authorities fail to identify human remains uncovered after a cyclone ravages the Western Australian coastline, Martin and Claire are sent to Broome, a popular holiday destination, far from major population centers. Posing as new arrivals, the SOC agents (offshoot of the Australian Security Intelligence Organization) attempt to merge with the locals in an effort to solve the baffling case and bring the killer to justice.
Lulled by the soporific influences of the sun, sand and surf - known by the locals as the Serenade of Broome - time seems to have no meaning for the two agents, and the investigation drifts from one location to another as they follow a trail of bodies designed to confuse and distract them from their real business in this tropical paradise.
Little do they know, their every move is being watched by an enemy who is both ruthless and deadly. A powerful, sadistic enemy who enjoys toying with others' lives before dispatching them in the most horrifying manner imaginable. As the clues lead them first one way then the other, they fall deeper and deeper into the trap set for them.
By the time they uncover the truth, they will begin to doubt everything they know and face their greatest challenge to date.
