A response reaches Hogwarts by Ministry Owl, shortly after breakfast. It is written neatly but hastily on fine parchment of good quality and the envelope smells faintly of Harper's perfume. It is heavy with several chocolate coins.
Dear Greer,
Thank you for reassuring me that you're fine - and I'm never too busy for my favourite client! That's a tricky question you're asking.
In an ideal world I guess you would appeal to the logic and rationality of the person-in-charge: state your case for why you think the student in question is lying. You could ask the person-in-charge why they think the student
isn't lying, and point out the problems in their reasoning. If there are other people of authority around you might also approach them. I'm not sure if I can offer any better advice without specific details.
What's the matter? What is this bad thing that has happened? I've slipped in some chocolates with this note.
Dutifully yours
Harper Graves
