Very addictive, I watched all four episodes in one sitting. An amazing pursuit of the truth by Steve Johnson of his brother Scott Johnson's death. As others have mentioned, Steve Johnson had the money and resources to pursue leads that others don't. I also understand that there was probably resentment in Australia of an American going there and trying to get media attention for his brother's case over unsolved Australian cases.
Initially it was botched by an inexperienced investigator and the case was closed, like most of the other gay murders in Manly. That suicide location appears to have been a murder location and it looks like nationalist groups just ran wild in that area.
I was struck by how naïve DCI Pamela Young was of the sensitivity of media interviews and attacking politicians. She spent time bashing the Johnson family instead taking leads and giving the family updates. DCI Yeomans was a professional, thankfully he was assigned the case and selected stellar detectives.
Not a full life sentence for the perp, but some justice for the victim.
