Have you noticed anything odd about this wall? It seems out of place somehow. Don't you see?

Look, it is much thicker than the other walls. I looked upstairs, at the rooms above this one and they are much thinner.

Fine, yes, I understand this is a cellar but it just doesn't make any sense. None of the other walls are like this one. What does the ultra-sound scanner show?

A void?

I knew it! And there is something else, you say, something organic. Do you mean like...

No?

A Skeleton! But the house is almost nine hundred years old!
