Summary

During Jim Cosgrove's childhood, a young man from his neighbourhood named Frank McGonigle disappeared without a trace. At various times throughout his life, Jim has been drawn back and retraced Frank’s steps, with various fascinating companions, inching closer and closer to finding out the truth about what happened to him.

It’s been 40 years now, and Jim has finally written the book about his life looking for Frank. It’s called ‘Ripple: A Long Strange Search For A Killer’. It really is a strange journey, and a very entertaining one to read about. He joins us to talk about it.

Do you believe that clairvoyance can be helpful in solving crimes?

0:12.3

Well, whether you do or you don't, we've got two episodes for you today that I'm sure you will find fascinating.

0:17.9

The first one is from the perspective of the childhood friend of a missing man,

and the second episode features the clairvoyant who helped crack the case.

This is Australian True Crime. We acknowledge the traditional owners of the land on which this

podcast is created, the Wurundri Woi Warang people of the Kulin Nation.

And a warning, this episode of the podcast

contains graphic descriptions of violence. Jim Cosgrove studied journalism very seriously as a young

0:48.9

man and he worked as a journalist for a long time. His own childhood was haunted by the

disappearance of a boy from his

neighborhood. And as you'll hear shortly, the children in Jim's neighborhood were a very,

Douglas, who a lot of us will know is the co-author of Mind Hunter and the man widely recognized as the

for the cover. Jim was clearly very proud but also a little bit embarrassed when I asked about the
