oh dear.
That's all a bit nasty isn't it. It's also a bit confusing; am I right in thinking three of the kids were raised by the grandparents/dad but the other three were kept in the cellar with the daughter. Jeeso.
Also, did it all get discovered because the eldest, Kerstin, was hospitalised? Imagine coming out of the cellar for the first time for that. I wonder how he got her out without his wife knowing.
What a total head fuck.
