My opinion is the latter one. If you read what I posted this morning it was a comparison based on what we are told of Eddie's abilities. I simply stated that there is as much reason to believe a connection with the deceased grandfather as there is to the claim that Madeleine died in the apartment. I added that at least in the former there was a body.
In my afternoon post I pointed out that we can but speculate since the facts surrounding the property occupation are unclear. I also reiterated the point made by Anne that cadaver scent fades over time so a connection going back several years is tenuous at best.
Hope you're winning at Candy Crush!
Unless there is some reason to believe that the Grandfather died in his own clothes and that the family wanted those clothes kept and that they were kept in 5a then I think there is a lot less reason to suspect dead Grandfather than dead Maddie.
P.S. If anyone has information as to cause of death, that may impact the probabilities.
Oh well, time for a double-backward somersault through a hoop while whistling the "Star Spangled Banner".
