Detective Mark Ariti has taken a few days’ holiday in Broken Bay at precisely the wrong time. The small fishing town on South Australia’s limestone coast is now the scene of a terrible tragedy.
Renowned cave-diver Mya Rennick has drowned while exploring a sinkhole on the land of wealthy farmer Francis Doyle. As the press descends, Mark’s boss orders him to stay put and assist the police operation.
However when the corpse is brought to the surface, it’s not Mya’s body they recover but that of Eloise Sinclair, a local girl who went missing over 20 years before. Suddenly Mark is diving deep into the town’s history – and in particular the simmering rivalry between its two most prominent families, the Doyles and Sinclairs.
Then Cherie Swinson, a former actress, is murdered in the Sinclairs’ old home – and Mark is left wondering which is more dangerous- Broken Bay’s hidden subterranean world or the secretive town above it . . .
