“Well, the Heads of the participating schools are always on the panel,” said Hermione, and everyone looked around at her, rather surprised, “because all three of them were injured during the Tournament of 1792, when a cockatrice the champions were supposed to be catching went on the rampage.”

She noticed them all looking at her and said, with her usual air of impatience that nobody else had read all the books she had, “It’s all in Hogwarts, A History. Though, of course, that book’s not entirely reliable. A Revised History of Hogwarts would be a more accurate title. Or A Highly Biased and Selective History of Hogwarts, Which Glosses Over the Nastier Aspects of the School.”

“What are you on about?” said Ron, though Harry thought he knew what was coming.

“House-elves!” said Hermione, her eyes flashing. “Not once, in over a thousand pages, does Hogwarts, A History mention that we are all colluding in the oppression of a hundred slaves!”

Harry shook his head and applied himself to his scrambled eggs. His and Ron’s lack of enthusiasm had done nothing whatsoever to curb Hermione’s determination to pursue justice for house-elves. True, both of them had paid two Sickles for a S.P.E.W. badge, but they had only done it to keep her quiet. Their Sickles had been wasted, however; if anything, they seemed to have made Hermione more vociferous. She had been badgering Harry and Ron ever since, first to wear the badges, then to persuade others to do the same, and she had also taken to rattling around the Gryffindor common room every evening, cornering people and shaking the collecting tin under their noses.

“You do realize that your sheets are changed, your fires lit, your classrooms cleaned, and your food cooked by a group of magical creatures who are unpaid and enslaved?” she kept saying fiercely.

Some people, like Neville, had paid up just to stop Hermione from glowering at them. A few seemed mildly interested in what she had to say, but were reluctant to take a more active role in campaigning. Many regarded the whole thing as a joke.

Ron now rolled his eyes at the ceiling, which was flooding them all in autumn sunlight, and Fred became extremely interested in his bacon (both twins had refused to buy a S.P.E.W. badge). George, however, leaned in toward Hermione.

“Listen, have you ever been down in the kitchens, Hermione?”

“No, of course not,” said Hermione curtly, “I hardly think students are supposed to—”

“Well, we have,” said George, indicating Fred, “loads of times, to nick food. And we’ve met them, and they’re happy. They think they’ve got the best job in the world—”
