^ It wasn't very gneiss at all!
This is why I feel a bit foolish...
My French colleague also heard the commotion but obviously knew it was nothing to do with her having a tantrum in the kitchen. And this all happened up her end of the building, just outside of her door and it must have been loud.
She went out and confronted this burglar, who she describes as a non-Scandinavian wearing a mask. He took off down the stairs.
She seems strangely reluctant to come knocking on my door at night... I can't understand why!
Muhammed slept through the whole thing... and he doesn't even have the excuse of whisky!
