I say this every chapter, but whoever is in charge of palace security should be fired and potentially arrested under a charge for assisting in espionage. I swear, at least 1 in 3 servants are secretly super spies or assassins. Get the person who constructed the palace as well for installing spaces above the ceilings of each room where spies can move freely.
I am really liking this though, especially in chapters where the king doesn't show up. I don't know how Sheila is supposed to go to "D" in the future though.
