The Lab Detective | Tortoise Investigates
The Observer
Introducing...The Lab DetectiveKathleen Folbigg 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.The full series is available to listen now.

Oliver’s company, Rebellion Defense, is on the rise. In 2019, it is full of promise and pumped with cash, trading on the hype around what’s possible with AI in war. It attracts influential backers and goes after big government contracts. And it becomes even harder to sort fact from fiction – where is the scrutiny, and who is checking that any of this stuff is… real? As Basia delves deeper into the world of artificial intelligence, she hears from another former girlfriend of Oliver’s who knows about the ‘tissue of lies’ – and why it matters now.
