Fifty fifty

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.
