In the dead of night, a meeting with a vet, who talks of an eerie event. It leads to a trail of toxins. Could Mobuoy still be a threat?

"All you have to do... is dig it up."

A trucker’s deathbed tape plays out. It’s urgent, desperate. In this BBC Radio 4 podcast series, investigative journalists Dan Ashby and Lucy Taylor deep-dive into one of the worst environment crimes in UK history - the secret dumping of a million tonnes of waste near a city. But when they uncover missing documents, fears of toxicity and allegations of organised crime, they realise they’ve stumbled into something much bigger. As they pick at the threads of one crime, they begin to see others. Could Britain be the home of a new mafia, getting rich on our waste?

In a thrilling ten-part investigation, the husband-and-wife duo dive into a criminal underworld, all the time following clues left in a deathbed tape. They’re driven by one question - what did the man in the tape know?
