Brittany banquet hall

Dear Lady British,

Spoiler: At times, I like to play piano in the banquet hall of the royal castle in Brittany.

The guards let me in so I thought some music could not hurt?

Spoiler: But, well, to tell you the truth : I think there's a ghost in your castle ! I would bet I see some dishes levitating.

Spoiler: On top of that, I think your carpenter made some mistakes with wall decorations.

I hope my report will be useful...

Please accept, Mylady, my respectful greetings.
