J. Rowling - Harry Potter and the Goblet of Fire

To their surprise, Professor Moody had announced that he would be putting the Imperius Curse on each of them in turn, to demonstrate its power and to see whether they could resist its effects.

“But—but you said it’s illegal, Professor,” said Hermione uncertainly as Moody cleared away the desks with a sweep of his wand, leaving a large clear space in the middle of the room. “You said—to use it against another human was—”

“Dumbledore wants you taught what it feels like,” said Moody, his magical eye swiveling onto Hermione and fixing her with an eerie, unblinking stare. “If you’d rather learn the hard way—when someone’s putting it on you so they can control you completely—fine by me. You’re excused. Off you go.”

He pointed one gnarled finger toward the door. Hermione went very pink and muttered something about not meaning that she wanted to leave. Harry and Ron grinned at each other. They knew Hermione would rather eat bubotuber pus than miss such an important lesson.

Moody began to beckon students forward in turn and put the Imperius Curse upon them. Harry watched as, one by one, his classmates did the most extraordinary things under its influence. Dean Thomas hopped three times around the room, singing the national anthem. Lavender Brown imitated a squirrel. Neville performed a series of quite astonishing gymnastics he would certainly not have been capable of in his normal state. Not one of them seemed to be able to fight off the curse, and each of them recovered only when Moody had removed it.

“Potter,” Moody growled, “you next.”

Harry moved forward into the middle of the classroom, into the space that Moody had cleared of desks. Moody raised his wand, pointed it at Harry, and said, “Imperio!”

It was the most wonderful feeling. Harry felt a floating sensation as every thought and worry in his head was wiped gently away, leaving nothing but a vague, untraceable happiness. He stood there feeling immensely relaxed, only dimly aware of everyone watching him.

And then he heard Mad-Eye Moody’s voice, echoing in some distant chamber of his empty brain: Jump onto the desk… jump onto the desk…

Harry bent his knees obediently, preparing to spring.

Jump onto the desk…

Why, though? Another voice had awoken in the back of his brain.

Stupid thing to do, really, said the voice.

Jump onto the desk…

No, I don’t think I will, thanks, said the other voice, a little more firmly… no, I don’t really want to.

Jump! NOW!

The next thing Harry felt was considerable pain. He had both jumped and tried to prevent himself from jumping—the result was that he’d smashed headlong into the desk knocking it over, and, by the feeling in his legs, fractured both his kneecaps.

“Now, that’s more like it!” growled Moody’s voice, and suddenly, Harry felt the empty, echoing feeling in his head disappear. He remembered exactly what was happening, and the pain in his knees seemed to double.

“Look at that, you lot… Potter fought! He fought it, and he damn near beat it! We’ll try that again, Potter, and the rest of you, pay attention—watch his eyes, that’s where you see it—very good, Potter, very good indeed! They’ll have trouble controlling you!”

“The way he talks,” Harry muttered as he hobbled out of the Defense Against the Dark Arts class an hour later (Moody had insisted on putting Harry through his paces four times in a row, until Harry could throw off the curse entirely), “you’d think we were all going to be attacked any second.”

“Yeah, I know,” said Ron, who was skipping on every alternate step. He had had much more difficulty with the curse than Harry, though Moody assured him the effects would wear off by lunchtime. “Talk about paranoid…” Ron glanced nervously over his shoulder to check that Moody was definitely out of earshot and went on. “No wonder they were glad to get shot of him at the Ministry. Did you hear him telling Seamus what he did to that witch who shouted ‘Boo’ behind him on April Fools’ Day? And when are we supposed to read up on resisting the Imperius Curse with everything else we’ve got to do?”

All the fourth years had noticed a definite increase in the amount of work they were required to do this term. Professor McGonagall explained why, when the class gave a particularly loud groan at the amount of Transfiguration homework she had assigned.

“You are now entering a most important phase of your magical education!” she told them, her eyes glinting dangerously behind her square spectacles. “Your Ordinary Wizarding Levels are drawing closer—”

“We don’t take O.W.L.s till fifth year!” said Dean Thomas indignantly.

“Maybe not, Thomas, but believe me, you need all the preparation you can get! Miss Granger remains the only person in this class who has managed to turn a hedgehog into a satisfactory pincushion. I might remind you that your pincushion, Thomas, still curls up in fright if anyone approaches it with a pin!”

Hermione, who had turned rather pink again, seemed to be trying not to look too pleased with herself.

Harry and Ron were deeply amused when Professor Trelawney told them that they had received top marks for their homework in their next Divination class. She read out large portions of their predictions, commending them for their unflinching acceptance of the horrors in store for them—but they were less amused when she asked them to do the same thing for the month after next; both of them were running out of ideas for catastrophes.

Meanwhile Professor Binns, the ghost who taught History of Magic, had them writing weekly essays on the goblin rebellions of the eighteenth century. Professor Snape was forcing them to research antidotes. They took this one seriously, as he had hinted that he might be poisoning one of them before Christmas to see if their antidote worked. Professor Flitwick had asked them to read three extra books in preparation for their lesson on Summoning Charms.

Even Hagrid was adding to their workload. The Blast-Ended Skrewts were growing at a remarkable pace given that nobody had yet discovered what they ate. Hagrid was delighted, and as part of their “project,” suggested that they come down to his hut on alternate evenings to observe the skrewts and make notes on their extraordinary behavior.

“I will not,” said Draco Malfoy flatly when Hagrid had proposed this with the air of Father Christmas pulling an extra large toy out of his sack. “I see enough of these foul things during lessons, thanks.”

Hagrid’s smile faded off his face.

“Yeh’ll do wha’ yer told,” he growled, “or I’ll be takin’ a leaf outta Professor Moody’s book… I hear yeh made a good ferret, Malfoy.”

The Gryffindors roared with laughter. Malfoy flushed with anger, but apparently the memory of Moody’s punishment was still sufficiently painful to stop him from retorting. Harry, Ron, and Hermione returned to the castle at the end of the lesson in high spirits; seeing Hagrid put down Malfoy was particularly satisfying, especially because Malfoy had done his very best to get Hagrid sacked the previous year.

When they arrived in the entrance hall, they found themselves unable to proceed owing to the large crowd of students congregated there, all milling around a large sign that had been erected at the foot of the marble staircase. Ron, the tallest of the three, stood on tiptoe to see over the heads in front of them and read the sign aloud to the other two:

TRIWIZARD TOURNAMENT

THE DELEGATIONS FROM BEAUXBATONS AND DURMSTRANG WILL BE ARRIVING AT 6 O’CLOCK ON FRIDAY THE 30TH OF OCTOBER. LESSONS WILL END HALF AN HOUR EARLY—

“Brilliant!” said Harry. “It’s Potions last thing on Friday! Snape won’t have time to poison us all!”
