'Do you know how to keep a secret?'

At the age of five, Molly Walker was placed in protective custody after witnessing the murder of her mother, Constable Sammi Walker. Twenty years later, everyone assumes the threat has passed.

Then Molly's adoptive parents are killed in a car accident, just after asking about reopening the investigation into Sammi's death. Coincidence or something more sinister?

Detective Jack Higgins doesn't believe in coincidences. And as he and Detective Angie Sullivan look into the accident, it becomes clear that this was a deliberate act. But is Molly still in danger, so long after the original crime?

From the blood-red soil of Kalgoorlie, long-buried lies continue to surface, while someone is becoming increasingly desperate to keep them hidden.
