Introducing... The Lab Detective

Tortoise Investigates

Available for 357 days

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, and an investigation into why Kathleen's story may not be the last.
