You are quite welcome to continue the story :-) My idea for the piece is that inside the wall is the skeleton of a baby, killed by being thrown into the concrete when the building was built decades ago. John becommes more and more interested in finding out whose child is crying every day, because there must be at child, eventhough Mrs. Anderson says there is none.

Well, I thought I could change the text, but apparently not ...

Thanks for the comment. And you are right. The last line got to go. (And it has :-))
