  • Introducing...The Gas Man


    It starts with a tip-off. 


    It’s the late 1980s and US Special Agent Dennis Bass is warned about a shipment of suspicious chemicals headed to a secret destination. So he follows the lead – and ends up stumbling into a global plot helping fuel a war. The main suspect? The Gas Man. 


    In the decades since, Special Agent Bass has been locked in an international game of cat and mouse with the man who supplied a dangerous regime with the chemicals to make weapons. Every time Bass thinks he’s got his hands on him… The Gas Man somehow manages to slip the net. And he’s still on the run today.


    But after more than 30 years, could his past finally be catching up with The Gas Man?

  • Introducing… Who Trolled Amber?


    What comes to mind when you think of Amber Heard? Liar? Survivor? Narcissist? Millions of us watched the celebrity trial of the century, Depp v Heard, in 2022. Amber Heard lost and Johnny Depp was vindicated. But what if Amber was actually the victim of an organised trolling campaign? What if the online hate against her was manufactured?


    Alexi Mostrous, the reporter who brought you Sweet Bobby and Hoaxed, investigates what happened to Amber and who might have been responsible. It’s a story about how our own thoughts and opinions can be moulded without us even realising.


    All six episodes of Who Trolled Amber are now available to binge-listen.

  • 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.

  • 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.

  • 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?

Then, she receives a text message that turns her life - and her relationship - upside down, and 10 years later, a mystery is still hanging over her. Walter's War is an investigation into what happened next – a journey through big tech and national security, hype and hucksterism, where anyone who can tell a good story can go far. But how much is true?
