Introducing...The Lab Detective

Kathleen Folbigg has experienced unimaginable loss. All four of her infant children died suddenly, over a 10-year period. Their deaths were unexplained. Until a police detective turned up at her door, and arrested Kathleen on suspicion of murder. She was labelled ‘Australia's worst female serial killer’, convicted, and was destined to spend most of the rest of her life in jail. Until a different type of detective entered her life. A scientist working in a lab who uncovered the truth behind the deaths. This is the story of a shocking miscarriage of justice, but as journalist Rachel Sylvester starts to investigate how this happened, she learns that Kathleen is not alone – other mothers have endured the same fate, and may also be in prison. The Lab Detective is a story about the power of science, and the determination of those searching for the truth.
