Introducing...Dangerous MemoriesWhen Sarah watched her 23 year old daughter cycle away from her in Chelsea - a well-off corner of London - she had no idea it would be the last time they’d see each other for 6 years. What would make a loving child from a life of privilege sever ties with friends and family, and disappear? It turns out, Sarah wasn’t alone in losing a daughter. Something strange was happening to other young women, too.And they all had one thing in common: a kind of therapist figure - a woman they were all seeing and sharing their problems, their secrets, their fears with. But it took years for the truth of what was happening behind closed doors to emerge, and the extraordinary things this woman led them to believe.Dangerous Memories is the story of young women who wanted to be healed that became, for us, a story about the healer, and what we risk when we let someone else into our mind, and our memory.To find out more about Tortoise:Download the Tortoise app - for a listening experience curated by our journalistsSubscribe to Tortoise+ on Apple Podcasts for early access and ad-free contentBecome a member and get access to all of Tortoise's premium audio offerings and moreIf you want to get in touch with us directly about a story, or tell us more about the stories you want to hear about contact hello@tortoisemedia.comReporter: Grace Hughes-HallettProducer: Gary MarshallAdditional reporting and production: Imogen HarperSound design and original composition: Tom KinsellaTheme music: Far Gone (Don’t Leave) by Pictish TrailPodcast artwork: Lola WilliamsCommissioning editor: Basia CummingsExecutive producer: Ceri Thomas Hosted on Acast.

This story starts in 2012. Oliver is a dashing young diplomat, working in Afghanistan. Charlie is a graduate newly arrived in London, trying to find her feet in the world. The pair meet online and she falls in love. But only a few months later, she discovers that the story Oliver has told her about his life is not what it seems. A decade later, this man has climbed to the top of academia, the civil service, and into the world of national security, eventually founding a billion-dollar company selling AI to the military. But a mystery hangs over Charlie: did the untruths continue, and if they did, why haven’t caught up with him?The first three episodes are available to Tortoise members on the free Tortoise audio app, and subscribers to Tortoise+ on Apple Podcasts.You can find out more about Tortoise:Download the Tortoise app - for a listening experience curated by our journalistsSubscribe to Tortoise+ on Apple Podcasts for early access and ad-free contentBecome a member and get access to all of Tortoise's premium audio offerings and moreIf you want to get in touch with us directly about a story, or tell us more about the stories you want to hear about contact hello@tortoisemedia.com Hosted on Acast.

Basia begins unravelling the ‘tissue of lies’, but it becomes clear that some of Oliver’s claims exist in the grey area, and in the secretive world in which he works, it’s hard to sift fact from fiction. Did he serve in the military? Is he an aristocrat? And as she traces his rise in national security, she is pulled into a bigger story – about a company, and a threat that is facing us all. The first three episodes are available to Tortoise members on the free Tortoise audio app, and subscribers to Tortoise+ on Apple Podcasts.You can find out more about Tortoise:Download the Tortoise app - for a listening experience curated by our journalistsSubscribe to Tortoise+ on Apple Podcasts for early access and ad-free contentBecome a member and get access to all of Tortoise's premium audio offerings and moreIf you want to get in touch with us directly about a story, or tell us more about the stories you want to hear about contact hello@tortoisemedia.com Hosted on Acast.

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. All four episodes are available to Tortoise members on the free Tortoise audio app, and subscribers to Tortoise+ on Apple Podcasts.You can find out more about Tortoise:Download the Tortoise app - for a listening experience curated by our journalistsSubscribe to Tortoise+ on Apple Podcasts for early access and ad-free contentBecome a member and get access to all of Tortoise's premium audio offerings and moreIf you want to get in touch with us directly about a story, or tell us more about the stories you want to hear about contact hello@tortoisemedia.com Hosted on Acast.

Things begin to fall apart. Only a few years after Rebellion Defense’s rapid rise, it appears to be in trouble. The rebellion has failed to take off. In the secretive world of the military and big tech, Basia is met with a wall of silence as she tries to see inside the company… until a few former staffers agree to speak to her, revealing what happened behind closed doors. You can find out more about Tortoise:Download the Tortoise app - for a listening experience curated by our journalistsSubscribe to Tortoise+ on Apple Podcasts for early access and ad-free contentBecome a member and get access to all of Tortoise's premium audio offerings and moreIf you want to get in touch with us directly about a story, or tell us more about the stories you want to hear about contact hello@tortoisemedia.com Hosted on Acast.
