So very close to 10 pm a woman appears at the night creche. Was she there to share the news or to collect a child? We don't know, but I would have thought her name would have been known if she was collecting a child. She was said to be the mother of a child in the Toddler 2 group.
I have wondered if it could have been Fiona. She knew Madeleine had disappeared and she was out and about at that time. I can't work out why she wasn't identified, though. Anyone else would have had to have moved very quickly and decisively, however.
Look the only reason I can see is that there is an earlier incident the PJ and the Ocean Club wish to keep confidential. So the times and information is correct, it is just that the identifying detail is kept out of it.
You seem to have sensed that too when you say "I can't work out why she wasn't identified".
Fiona is so unlikely to have been that woman. They had the child monitor so they say they didn't move from the table.
It is the lady who had previously spoken to the man looking for the child that makes it all the way to the main reception. Trouble was he called her Maddie or Gabbie, so could the other missing child in the earlier incident be named Gabriel, so gets called Gabbie as much as Madeleine is shortened to Maddie?
For it is the deduction work by the creche staff who figure that it could have been Madeleine McCann, on a different day their deductions could have been all wrong, but that night they fluked it and got it right.
So I find I've made a concession here, either there was a another missing girl named Gabbie or there was someone looking for Madeleine up to 20 minutes before Kate came back saying Madeleine has gone.
