Since I was already fairly far advanced in the book I'd been reading / listening to for this card when Nighttime Reading Center posted her guess (congrats again on getting there first! :) ), the team agreed I'd just finish my book and claim the card for the points awarded for a crime scene already revealed by someone else's guess.
Obviously, Harry Potter and the Philosopher's Stone fulfills all three tasks associated with this card -- Gryffindor is the house whose students most embody bravery, Hogwarts is brimming with magic, and the audio version very prettily displays the Gryffindor colors of scarlet (red) and gold (yellow).
