One accident. No survivors. So where are the bodies? This is David Raker's most heart-pounding and tense case yet.

Ten seconds before the crash, Cate and Aiden Gascoigne are recorded on CCTV. The couple are laughing - happy, untroubled.

Then their car plunges into a ninety-foot ravine.

The impact should kill them. And if that doesn't, the fire will. Within seconds, the vehicle is an inferno - with the Gascoignes trapped inside.

But when fire crews arrive at the scene, they find something impossible.

The vehicle is empty.

Cate and Aiden have vanished.

Now only missing persons investigator David Raker can solve the mystery . . .
