If Madeleine was alive, in what sort of circumstances would she be living?
Everything below is pure speculation, based upon the likely lifestyle of my suspect.I think that she will be living a rather nice lifestyle, but she will miss the fun of her home at Rothley with her fun filled Daddy and much loved Mummy. She will sorely miss the twins too.
However, I fear that she will be restricted in many ways and moved on fairly frequently, leaving friends behind. That is not nice. I also wonder if she has unhappily been been subjected to mind alteration, possibly by shamans in the Drakensberg mountains of Lesotho, where I believe she has visited the other "Fatima"
She will probably mainly travel by luxury yacht and slip into countries within the Schengen agreement quite easily. She will probably also visit other countries, by docking in small harbours. Money is no object, so she will probably also travel by private plane.
All the above is pure speculation, based upon the likely lifestyle of my suspect.
