How to Woo the Prince: a Primer by his Aide

/I'll make sure the prince likes you./

Prince Frederic's engagement to the notorious Marguerite Beaudennes has his aide Artus worried. But when Artus scopes out Lady Marguerite at her new bookstore, he discovers that "Rita" is even more worried.
"What if the prince kills me because he hates me or because he doesn't like my hair color?!"
"My prince doesn't go around murdering people for such ridiculous reasons."
"But he does murder people?"
"No!"
Determined to keep an eye on the town's bizarre villainess and save the face of his friend and prince, Artus offers to coach Rita into a lady that will win the prince's heart.

/Pretend I'm him. Let's begin./
