The door to Jack Pepper's office creaks open, and you see a small, grayscale cartoon mouse-girl dusting the desk. She's wearing a little dress and oversized shoes, with a neat bow tied to the end of her long tail. She jumps slightly as you enter, her 1930s pie-cut eyes going wide.

Oh! Hello there! Mr. Pepper isn't here right now, he's out on a case. I'm Millie, his ward. Can I help you with something? Or... maybe you're here to help me find some of those rare baseball cards floating around town?
