Yes it is a nice story.
Only the conspiracy theorists will be disappointed.
The people that count in Thailand, government and its employees, are happy with the findings of suicide. (As in the BP and others.)
Mind you, they are even more happy that they are sniffing around looking to see if the poor French lady's company set up is valid or if it used nominee shareholders.
The interior ministry will be looking to get their hands on the business if it is illegal and then they will be allowed to sell it's assets.
Still, the maid will still have the 500k and any possible bank accounts and other items in the estate.
