The Gas Man | Tortoise Investigates

Tortoise Media

Introducing..The Gas Man

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?

Our Editor's Take

Could someone fall in love with a person they haven't even met? Sweet Bobby is an investigation podcast that takes listeners on a journey of discovery to find the truth. After host Kirat Assi meets a wonderful man online, she finds herself falling. But who is Bobby? The more she gets to know him, the more there is that doesn't quite add up. As lies build, Kirat starts to wonder if she knows Bobby at all. Listeners can follow along as she dives into finding out the truth about Bobby. She may think she is only looking for answers about her beau, but it becomes a search for a high-level catfisher. The episodes run in real-time as she uncovers secrets and unsettling facts about the man she thought she knew.

Dynamic, gripping and shocking, this podcast is a must-listen. It is the perfect listen for fans of true crime, investigative stories, and TV shows like Catfish. Each twist and turn will surprise, and listeners will feel the rollercoaster of emotions alongside Kirat as she unpacks a life full of lies. Epic scams, layers of deceit, and a web of deceit will reel audiences in. Uncovering the truth will compel them to stay. This show is perfect for those who love stories like the Tinder Swindler or Inventing Anna. It is catfishing at its finest…and most dangerous.

Listeners are already raving about the Sweet Bobby podcast. It has gained the attention of media companies, and garnered over a million viewers from across the globe. It is one of the best podcast series around. The real-life story will captivate listeners. But Kirat's story is also relatable—how many people have also been too trusting and fallen for a stranger? Emotional, tense and down-right entertaining, this podcast is a must-add to any playlist.
