It just seems to me to odd. They died in the perfect odd for the daughter to inherit.
First the son in law dies suddenly, leaving ANS in a much stronger standing in the inheritance dispute. Next her son dies, most likely her heir. Now she dies, leaving to either her husband (if there is one) or her child. I would look at HJS or the photog if he gets the child.
Ok, I watch way too much Hercule.
