The latest report into gangland snitch Nicola Gobbo's scandalous relationship with Victoria Police, due to be released on Monday, is sure to be the most damning.
A former police chief, anti-corruption investigator and Australia's High Court have all slammed the Lawyer X affair, labelling the behaviour as reprehensible and negligent.
But Margaret McMurdo's royal commission report comes at the end of a nearly two-year long inquiry where some of the worst aspects of the saga were revealed and examined for the first time.
The report brings with it the potential for prosecution of Ms Gobbo and the police who were closest to her, as well as more convictions being overturned as a result of what many say is the darkest period in Victoria's legal history.
It will also be the first report into the saga to be released publicly at the same time as those involved read it.
Two people have already had convictions overturned and dozens more are lining up to be next, including one of the country's most recognisable crims, Tony Mokbel.
Up to 1000 more people could have had their cases tainted by Ms Gobbo's informing against clients.
Ms McMurdo, a former Queensland Supreme Court Justice, has already revealed she won't recommend criminal charges herself.
But the appointment of a special prosecutor to build a case has been flagged.
Anti-corruption watchdog IBAC also has the potential to investigate.
It has before.
Murray Kellam's scathing 2015 findings were released during the latest inquiry, including claims former Victoria Police boss Graham Ashton once described her as a "glittering prize".
Much has changed since then though, including revelations she was recruited as an informer against an ex-lover in 1995 and against her then-employer in 1997.
The scandal has been pulled apart and examined from every conceivable angle.
Senior police were grilled, handlers spent weeks in the witness box defending how they used her, and crooks claimed they spent years behind bars solely because she turned on them.
Ms Gobbo eventually appeared herself by phone in February.
She claimed she was glad to be there, but the effort it took getting her implied otherwise.
Her first two registrations as an informer were news to her, she claimed. Her explanation for the third registration bounced between claims she wanted to get the "Mokbel monkey" off her back and to escape the gangland clutches, and admissions she loved being the centre of it.
"And as pathetic as it is for me to admit, looking back I did derive some self-importance and some feeling that I was relevant, or validated, by reason of being wanted by people like Tony (Mokbel)," she said.
A large part of the inquiry was spent untangling decades of her lies - whether much stock can be taken from what she told the inquiry remains to be seen.
No doubt Ms McMurdo will have her views.
Her role in the affair will end on Monday when she presents her final report to Governor Linda Dessau. It's expected to be tabled in parliament and released publicly the same day.
What Ms Gobbo or Victoria Police make of the recommendations will remain to be seen.
In September Victoria Police conceded that allowing Ms Gobbo to inform on clients was "profoundly wrong".
"Our failure at that time to ensure that these circumstances were identified and disclosed was also a significant and missed opportunity to right a wrong," the force said, with an apology to the courts.
Ms Gobbo is in hiding.
