Rachael Brown is back, hosting the latest season of the ABC's biggest investigative true crime podcast Unravel. It's called Huntsman, and it's already rocketing up the podcast charts.

You might remember when former Jetstar pilot Greg Lynn was convicted of murder in the High Country. The story made headlines when Lynn admitted to burning the campers' bodies to cover his tracks.

But behind the scenes, people who knew him years ago began talking and sending messages.

It sparked an ABC investigation that uncovered the full story of his dark past and his abusive relationship with his first wife, Lisa Lynn, which ended in tragedy.

In this new season, investigative reporter and Trace host Rachael Brown uncovers the details of Greg Lynn's former life and the fear and damage he left behind him in the suburbs.

You can find the podcast on ABC listen, or search for Unravel: Huntsman wherever you get your podcasts.
