Harry knew that Hermione had meant well, but that didn’t stop him from being angry with her. He had been the owner of the best broom in the world for a few short hours, and now, because of her interference, he didn’t know whether he would ever see it again. He was positive that there was nothing wrong with the Firebolt now, but what sort of state would it be in once it had been subjected to all sorts of anti-jinx tests?

Ron was furious with Hermione too. As far as he was concerned, the stripping-down of a brand-new Firebolt was nothing less than criminal damage. Hermione, who remained convinced that she had acted for the best, started avoiding the common room. Harry and Ron supposed she had taken refuge in the library and didn’t try to persuade her to come back. All in all, they were glad when the rest of the school returned shortly after New Year, and Gryffindor Tower became crowded and noisy again. Wood sought Harry out on the night before term started.

“Had a good Christmas?” he said, and then, without waiting for an answer, he sat down, lowered his voice, and said, “I’ve been, doing some thinking over Christmas, Harry. After last match, you know. If the Dementors come to the next one…I mean…we can’t afford you to — well —”

Wood broke off, looking awkward.

“I’m working on it,” said Harry quickly. “Professor Lupin said he’d train me to ward off the Dementors. We should be starting this week. He said he’d have time after Christmas.”

“Ah,” said Wood, his expression clearing. “Well, in that case — I really didn’t want to lose you as Seeker, Harry. And have you ordered a new broom yet?”

“No,” said Harry.

“What! You’d better get a move on, you know — you can’t ride that Shooting Star against Ravenclaw!”

“He got a Firebolt for Christmas,” said Ron.

“A Firebolt ? No! Seriously? A — a real Firebolt ?”

“Don’t get excited, Oliver,” said Harry gloomily. “I haven’t got it anymore. It was confiscated.” And he explained all about how the Firebolt was now being checked for jinxes.

“Jinxed? How could it be jinxed?”

“Sirius Black,” Harry said wearily. “He’s supposed to be after me. So McGonagall reckons he might have sent it.”

Waving aside the information that a famous murderer was after his Seeker, Wood said, “But Black couldn’t have bought a Firebolt! He’s on the run! The whole country’s on the lookout for him! How could he just walk into Quality Quidditch Supplies and buy a broomstick?”

“I know,” said Harry, “but McGonagall still wants to strip it down —”

Wood went pale.

“I’ll go and talk to her, Harry,” he promised. “I’ll make her see reason…A Firebolt…a real Firebolt, on our team …She wants Gryffindor to win as much as we do…I’ll make her see sense. A Firebolt.… ”

Classes started again the next day. The last thing anyone felt like doing was spending two hours on the grounds on a raw January morning, but Hagrid had provided a bonfire full of salamanders for their enjoyment, and they spent an unusually good lesson collecting dry wood and leaves to keep the fire blazing while the flame-loving lizards scampered up and down the crumbling, white-hot logs. The first Divination lesson of the new term was much less fun; Professor Trelawney was now teaching them palmistry, and she lost no time in informing Harry that he had the shortest life line she had ever seen.

It was Defense Against the Dark Arts that Harry was keen to get to; after his conversation with Wood, he wanted to get started on his anti-Dementor lessons as soon as possible.

“Ah yes,” said Lupin, when Harry reminded him of his promise at the end of class. “Let me see…how about eight o’clock on Thursday evening? The History of Magic classroom should be large enough…I’ll have to think carefully about how we’re going to do this…We can’t bring a real Dementor into the castle to practice on….”

“Still looks ill, doesn’t he?” said Ron as they walked down the corridor, heading to dinner. “What d’you reckon’s the matter with him?”

There was a loud and impatient “tuh” from behind them. It was Hermione, who had been sitting at the feet of a suit of armor, repacking her bag, which was so full of books it wouldn’t close.

“And what are you tutting at us for?” said Ron irritably.

“Nothing,” said Hermione in a lofty voice, heaving her bag back over her shoulder.

“Yes, you were,” said Ron. “I said I wonder what’s wrong with Lupin, and you —”

“Well, isn’t it obvious ?” said Hermione, with a look of maddening superiority.

“If you don’t want to tell us, don’t,” snapped Ron.

“Fine,” said Hermione haughtily, and she marched off.

“She doesn’t know,” said Ron, staring resentfully after Hermione. “She’s just trying to get us to talk to her again.”

At eight o’clock on Thursday evening, Harry left Gryffindor Tower for the History of Magic classroom. It was dark and empty when he arrived, but he lit the lamps with his wand and had waited only five minutes when Professor Lupin turned up, carrying a large packing case, which he heaved onto Professor Binn’s desk.

“What’s that?” said Harry.

“Another Boggart,” said Lupin, stripping off his cloak. “I’ve been combing the castle ever since Tuesday, and very luckily, I found this one lurking inside Mr. Filch’s filing cabinet. It’s the nearest we’ll get to a real Dementor. The Boggart will turn into a Dementor when he sees you, so we’ll be able to practice on him. I can store him in my office when we’re not using him; there’s a cupboard under my desk he’ll like.”

“Okay,” said Harry, trying to sound as though he wasn’t apprehensive at all and merely glad that Lupin had found such a good substitute for a real Dementor.

“So…” Professor Lupin had taken out his own wand, and indicated that Harry should do the same. “The spell I am going to try and teach you is highly advanced magic, Harry — well beyond Ordinary Wizarding Level. It is called the Patronus Charm.”

“How does it work?” said Harry nervously.

“Well, when it works correctly, It conjures up a Patronus,” said Lupin, “which is a kind of anti-Dementor — a guardian that acts as a shield between you and the Dementor.”

Harry had a sudden vision of himself crouching behind a Hagrid-sized figure holding a large club. Professor Lupin continued, “The Patronus is a kind of positive force, a projection of the very things that the Dementor feeds upon — hope, happiness, the desire to survive — but it cannot feel despair, as real humans can, so the Dementors can’t hurt it. But I must warn you, Harry, that the charm might be too advanced for you. Many qualified wizards have difficulty with it.”

“What does a Patronus look like?” said Harry curiously.

“Each one is unique to the wizard who conjures it.”

“And how do you conjure it?”

“With an incantation, which will work only if you are concentrating, with all your might, on a single, very happy memory.”

Harry cast his mind about for a happy memory. Certainly, nothing that had happened to him at the Dursleys’ was going to do. Finally, he settled on the moment when he had first ridden a broomstick.

“Right,” he said, trying to recall as exactly as possible the wonderful, soaring sensation of his stomach.

“The incantation is this —” Lupin cleared his throat. “Expecto patronum !”

“Expecto patronum,” Harry repeated under his breath, “expecto patronum.”

“Concentrating hard on your happy memory?”

“Oh — yeah —” said Harry, quickly forcing his thoughts back to that first broom ride. “Expecto patrono — no, patronum — sorry — expecto patronum, expecto patronum”

Something whooshed suddenly out of the end of his wand; it looked like a wisp of silvery gas.

“Did you see that?” said Harry excitedly. “Something happened!”

“Very good,” said Lupin, smiling. “Right, then — ready to try it on a Dementor?”

“Yes,” Harry said, gripping his wand very tightly, and moving into the middle of the deserted classroom. He tried to keep his mind on flying, but something else kept intruding…Any second now, he might hear his mother again…but he shouldn’t think that, or he would hear her again, and he didn’t want to…or did he?

Lupin grasped the lid of the packing case and pulled.

A Dementor rose slowly from the box, its hooded face turned toward Harry, one glistening, scabbed hand gripping its cloak. The lamps around the classroom flickered and went out. The Dementor stepped from the box and started to sweep silently toward Harry, drawing a deep, rattling breath. A wave of piercing cold broke over him —

“Expecto patronum !” Harry yelled. “Expecto patronum ! Expecto —”

But the classroom and the Dementor were dissolving…Harry was falling again through thick white fog, and his mother’s voice was louder than ever, echoing inside his head — “Not Harry! Not Harry! Please — I’ll do anything —”

“Stand aside — stand aside, girl —”

“Harry!”

Harry jerked back to life. He was lying flat on his back on the floor. The classroom lamps were alight again. He didn’t have to ask what had happened.

“Sorry,” he muttered, sitting up and feeling cold sweat trickling down behind his glasses.

“Are you all right?” said Lupin.

“Yes…” Harry pulled himself up on one of the desks and leaned against it.

“Here —” Lupin handed him a Chocolate Frog. “Eat this before we try again. I didn’t expect you to do it your first time; in fact, I would have been astounded if you had.”

“It’s getting worse,” Harry muttered, biting off the Frog’s head. “I could hear her louder that time — and him — Voldemort —”

Lupin looked paler than usual.

“Harry, if you don’t want to continue, I will more than understand —”

“I do!” said Harry fiercely, stuffing the rest of the Chocolate Frog into his mouth. “I’ve got to! What if the Dementors turn up at our match against Ravenclaw? I can’t afford to fall off again. If we lose this game we’ve lost the Quidditch Cup!”

“All right then…” said Lupin. “You might want to select another memory, a happy memory, I mean, to concentrate on…That one doesn’t seem to have been strong enough…”

Harry thought hard and decided his feelings when Gryffindor had won the House Championship last year had definitely qualified as very happy. He gripped his wand tightly again and took up his position in the middle of the classroom.
