Original Description:
 
(Inspector Mare)  
Ooohhhh, so THAT may explain the dirt mark on the desk. That lantern must’ve gotten dirty when she must’ve accidentally dropped it at the garden, before the lantern ended up staining the table with the bottom mark.
 
However, as soon as Miss Moonbow returned back to her bed, the culprit must’ve snuck in and took the lantern off the table, and left behind a series of hoof tracks that led us straight back to the garden…
 
After burying the stolen lantern, the culprit then sprinkled the spot with the glitter, ran off to check the other houses for valuables, and finally return back to the glittery spot to retrieve the lantern before the break of dawn!
