I don't think "Who" created a Company is all that important. I have always understood that Edgar and Cowley were employed and supported by Brian Kennedy on behalf of The McCanns.
Someone tried to turn Aphaig into some sort of mystery. Bennett, I do believe. But why should it matter what Edgar and Cowley called themselves?
I hope they do run some sort of Agency now that they don't appear to be searching for Madeleine. Although we can't be sure that they aren't doing that. It would hardly be Interfering with the Course of Justice since this remains a Portuguese Investigation.
Well nothing has come up on Company Check or the equivalents. Theyappear to have disappeared into oblivion, unless working for someone else.
The impression given at the time to the media was of independent organizations,not ones specifically 'set-up' to deal with a potential abduction
IMO, the incompetence was highlighted by one section involving the 'Beckham' lookalike, where the port authority in Barcelona and nearby businesses recorded no visits by anyone questioning about the private yacht and the woman requesting where her new child was. Now that story became worldwide and revealed as we know NOTHING.
