Pig Iron

Introducing...Dangerous Memories

When 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. The first 2 episodes are out now and released weekly. To binge-listen to all 6 episodes ad-free from today, subscribe to Tortoise+ or download the Tortoise app

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?

The first two episodes of The Gas Man are available now, with further episodes released each week. To get ad-free and early access to more episodes today, become a Tortoise member or subscribe to Tortoise+.

Introducing Walter's War, a brand new investigation from Tortoise. 

It’s London, 2012. Oliver is a dashing diplomat. Charlie is a young graduate trying to find her feet in the world. They meet online and she falls in love. With his encouragement, Charlie applies for a job in British intelligence. 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?
