Introducing...The Lab Detective

Kathleen Folbigg was known as ‘Australia's worst female serial killer’ - she’d lost all four of her infant children and was convicted for killing them.

Until, after spending decades in jail, a scientist working in a lab uncovered the truth behind the deaths. 

The Lab detective is the story of a shocking miscarriage of justice, and an investigation into why Kathleen’s story might not be the last.
