Hogwarts letter to Astor Bellchant

"What have we here?… A letter from Hogwarts to a parent? I wonder who it — Ah, there's a name here! Albert Bellchant? That's Astor's son! Oh dear, it isn't exactly glowing with praise. He's failing Transfiguration, Charms, and Herbology! Not exactly living up to the family name, is he? Wait, Edgar! Wasn't that bottle we found in Bilius's apron labelled 'for mental acuity'? What is Bilius was blackmailed into brewing a potion for Astor's son?"

- Mathilda Grimblehawk, after her partner had Mended a torn letter from Hogwarts

This letter was sent from Hogwarts School of Witchcraft and Wizardry to Astor Bellchant, to inform him of his son Albert's poor marks in Transfiguration, Charms, and Herbology.

Knowledge of Albert's failing marks motivated Astor to blackmail Bilius Finbok, with whom he had attended Hogwarts, into brewing an illegal mental acuity potion.

Ministry of Magic investigators Mathilda Grimblehawk and her partner looked into the situation after Finbok was injured by a magical creature and sent to the hospital by a Muggle neighbour. They discovered this letter, which had been torn to shreds, in Finbok's potions lab in his basement.
