Fifty Fifty book description
Sam Blue stands accused of the brutal murders of three young students, their bodies dumped near the Georges River. Only one person believes he is innocent: his sister, Detective Harriet Blue. And she’s determined to prove it.
But Harry’s outburst at her brother’s trial earns her a reassignment–to the outback. With no choice but to leave Sam’s case alone, she relocates to Last Chance Valley, population 75, where a diary found on the roadside outlines a shocking plan: the massacre of the entire town. And the first killing, shortly after Harry’s arrival, suggests the clock is already ticking.
Meanwhile, back in Sydney, a young woman holds the key to crack Sam’s case wide open. If only she could escape the madman holding her hostage . . .
