More dust. Her nose was starting to itch from the dust and it felt like she was going to have to take a thousand and one showers to remove all the dust from her later, but not that any of it mattered now. Her focus was on trying to decipher this riddle.

Carefully opening the lid for the piano, she blinked as she considered more of the verses to the riddle. Pigletted friends. Wait, wait, at the castle. There were no pigs at the castle? But what if it was referring to piglets as in a hairstyle? The hairstyle that didn't they have a ghost ... Myrtle who took up residence in the girl's bathroom on the second floor? Who wore glasses? If memory served Louise right, although she was rather rusty with her Hogswartian Magical History, but it might have made sense because glasses had the double meaning of amending a house, and they were also important to those boys and girls at the castle ...

So was she looking for a pair of eyeglasses then? Maybe in that toilet on the first floor?!?

If she didn't find anything of substance under this piano lid, then perhaps she would head back down the first floor have a look, while holding her nose too.
