Introducing: Australia's Killer Secrets

In 2007, four people vanished from a remote town in Western Australia - leaving behind an abandoned home, a cryptic note and a trail of unanswered questions. 
At the centre of the mystery was a self-styled spiritual leader, who had built an online doomsday cult. Over the past 20 years, as desperate family, police and coroners examined theories ranging from suicide pacts to staged disappearances, the truth behind the so-called “Nannup Four” only became more disturbing.
In this episode, ABC journalist Dominique Bayens - behind the investigative podcast ‘Expanse: The Nannup Four’ -  joins Tim and Xanthe to examine this mystery, and discuss the disturbing psychology behind what has become one of Australia’s strangest and most unsettling cult cold cases.
