I'm thinking it's increasingly likely that Christian is guilty, but I think there are some reasonable feelings that folk have on Gerry and Kate.
Things Iike saying the window was jenmied, like immediately thinking someone had taken her. My first feeling would be that she'd wondered out looking for us after waking up and being frightened.
Also the twins not only sleeping through but for hours afterwards and not having them tested, I do think at the very least they made sure they were sleeping before going out.
Before Christian was on the scene I thought that Madeleine had woken up, groggy, either heard her daddy talking to Jez outside, climbed up and fell behind the settee into the tiled floor, hence the dogs scenting there and on Kates clothing.
Then I realised how much of an armchair detective I'd been and how on earth did they get rid of a precious child and even if they could, where and when did they do that?
So I do think it's back to Christian, and it's tragic for her family that they will never know.
