Contrast Gerry's visit with Kate's later.
From Peter Mac's E book for the text "In 2008 Kate McCann gave an interview in which she described graphically what happened when she entered the apartment for her check, and discovered Madeleine to be missing.
“I did my check about ten o’clock and went in through the sliding patio doors, and I just stood actually, and I thought, uh, all quiet. And to be honest, I might have been tempted to turn round then, but I just noticed that the door, the bedroom door where the three children were sleeping, was open much further than we’d left it.
I went to close it to about here, and then as I got to here, it suddenly . . . slammed, and as I opened it, it was then, that I just thought I’ll just look at the children.
I see Sean and Amelie in the cot . . . .
I was looking at Madeleine’s bed which is here, and it was dark and I was looking and I was thinking is that, is that Madeleine or is that the bedding and I couldn't quite make her out, and it sounds really stupid now, but at the time I was just thinking I didn’t want to put the light on because I didn't want to wake them, and literally as I went back in, the curtains of the bedroom which were drawn, [demonstrates with both forearms together] that were closed, “wheesh’ like a gust of wind kind of blew them open.
And cuddle cat was still there, and the pink blanket was still there. I knew straight away that, err, she’d been . . . taken, yer know.”
I think that just about confirms the main difference is one turned the light on and the other didn't, but also didn't need to because of the extra light coming through the curtain because the shutters were up.
