In March of 2020, days before the world began to lock down, Russell Hill and Carol Clay ventured to Alpine National Park for a camping trip. When over a week passed without a word from them, the families of the elderly pair grew worried. What investigators discovered was a burnt down campsite, but not the campers. What ensued over the next 18 months unfolded as one of Australia’s most intriguing missing persons cases - which resulted in uncovering an illicit affair, a brutal murder and raised questions of other mysterious cases of the past.
