Christopher Allen was trying to make it as a war reporter when, aged just 26, he was shot and killed on the frontline in South Sudan. But as news of his death began to spread, suspicion grew. Some claimed he was really there as a mercenary, a fighter. Others said he was a reckless freelancer, in over his head. And there was another question: was he killed on purpose, or was this another accident of war? From Tortoise and the team behind Sweet Bobby, Pig Iron is a dark adventure in war and journalism – and into what really happened to Christopher Allen.

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+.
