In a follow-up to her powerful interview with Stefanie Hinrichs - who lost her childhood to one of Australia's most dangerous sex predators - Polly speaks with Megan Norris, the author of The Messiah's Bride.
Hinrichs was just 11 years old when she was forced to become the self-proclaimed Messiah's child bride.
Norris, who is an investigative journalist, has detailed the story of Stefanie's journey. From moving to Australia to finding herself trapped in an illicit sexual relationship with the Doomsday cult leader William Kamm, also known as 'Little Pebble'.
"He does suffer from a narcissistic personality disorder. He thinks he's God. He thinks he's more superior and cleverer than everybody and he gets off on that," Norris told Polly.
"I do not know what the appeal of that odd little man could be. I just don't get it."
