 When Grace walks the Queen's dogs, she always goes to visit her friends Masou and Ellie in a hideout.Every time the Queen wants to move to another Palace, Masou and Ellie find a little hideaway in the orchard to go in there in their spare time, when they are not helping Lady Grace solve a new mystery.The thing that Grace hates is when Ellie and Masou have to treat her like a Maid of Honour, and call her "mistress" and "lady".
