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.

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?

In a year when four billion people are heading to the polls, and with the World Economic Forum warning that online misinformation is the most severe risk the world faces, Who Trolled Amber? shines a light on the shady industry of social media manipulation. It reveals how bots and trolls can sway opinions from celebrity trials to general elections.

On June 12th Alexi Mostrous will be joined by Jen Robinson, Amber Heard’s lawyer, and Gina Neff, Executive Director of the Minderoo Centre for Technology and Democracy at the University of Cambridge in the Tortoise newsroom to discuss Who Trolled Amber? and give their insights into the world of online disinformation and its effect on all of our everyday lives.
