The signing in of the Carpe Ter child, on the afternoon of Tuesday 1st May 2007 at 14.40hrs ( 10 minutes behind Madeleine McCann) is somewhat significant I would suggest, because it places the Carpenter family behind whatever and wherever the McCanns and their children went, or did!
Because the Carpenter child's name was scored through, it appears to me that once they had booked their child in after Madeleine, they took her back out straight away without signing for her return or the hand back!
This may prove costly to the Carpenters, because it suggests amongst other things that they could have been stalking the McCanns from the early part of the holiday!
