And at least a partial happy ending.
That is the story of an unassuming couple that traveled the world and were kind to their neighbours.
It is the story of the thieves that ran away with at least one multi-million dollar painting and left more than million dollars in savings, from a low middle-class income.
And it is the story of a nephew handling the estate of his deceased uncle and aunt, finding a truth he could not predict.
But also the story of that one painting being returned. If nothing else, watch from 18:45 in this video:
I say partial happy ending, because it is plausible that the couple stole other items and possibly sold them, considering their lifestyle, earnings and savings.
