“There was no need to stick the wand in that hard,” he said gruffly, clambering to his feet. “It hurt.”

The wandlight sparkled on his shiny pate, his prominent eyes, his enormous, silver, walruslike mustache, and the highly polished buttons on the maroon velvet jacket he was wearing over a pair of lilac silk pajamas. The top of his head barely reached Dumbledore’s chin.

“What gave it away?” he grunted as he staggered to his feet, still rubbing his lower belly. He seemed remarkably unabashed for a man who had just been discovered pretending to be an armchair.

“My dear Horace,” said Dumbledore, looking amused, “if the Death Eaters really had come to call, the Dark Mark would have been set over the house.”

The wizard clapped a pudgy hand to his vast forehead.

“The Dark Mark,” he muttered. “Knew there was something… ah well. Wouldn’t have had time anyway, I’d only just put the finishing touches to my upholstery when you entered the room.”

He heaved a great sigh that made the ends of his mustache flutter.

“Would you like my assistance clearing up?” asked Dumbledore politely.

“Please,” said the other.

They stood back to back, the tall thin wizard and the short round one, and waved their wands in one identical sweeping motion.

The furniture flew back to its original places; ornaments re-lormed in midair, feathers zoomed into their cushions; torn books repaired themselves as they landed upon their shelves; oil lanterns soared onto side tables and reignited; avast collection of splintered silver picture frames flew glittering across the room and alighted, whole and untarnished, upon a desk; rips, cracks, and holes healed everywhere, and the walls wiped themselves clean.

“What kind of blood was that, incidentally?” asked Dumbledore loudly over the chiming of the newly unsmashed grandfather flock.

“On the walls? Dragon,” shouted the wizard called Horace, as, with a deafening grinding and tinkling, the chandelier screwed itself back into the ceiling.

There was a final plunk from the piano, and silence.

“Yes, dragon,” repeated the wizard conversationally. “My last bottle, and prices are sky-high at the moment. Still, it might be reusable.”

He stumped over to a small crystal bottle standing on top of a sideboard and held it up to the light, examining the thick liquid within.

“Hmm. Bit dusty.”

He set the bottle back on the sideboard and sighed. It was then that his gaze fell upon Harry.

“Oho,” he said, his large round eyes flying to Harry’s forehead and the lightning-shaped scar it bore. “Oho!”

“This,” said Dumbledore, moving forward to make the introduction, “is Harry Potter. Harry, this is an old Friend and colleague of mine, Horace Slughorn.”

Slughorn turned on Dumbledore, his expression shrewd. “So that’s how you thought you’d persuade me, is it? Well, the answer’s no, Albus.”

He pushed past Harry, his face turned resolutely away with the air of a man trying to resist temptation.

“I suppose we can have a drink, at least?” asked Dumbledore. “For old time’s sake?”

Slughorn hesitated.

“All right then, one drink,” he said ungraciously.

Dumbledore smiled at Harry and directed him toward a chair not unlike the one that Slughorn had so recently impersonated, which stood right beside the newly burning fire and a brightly glowing oil lamp. Harry took the seat with the distinct impression that Dumbledore, for some reason, wanted to keep him as visible as possible. Certainly when Slughorn, who had been busy with decanters and glasses, turned to face the room again, his eyes fell immediately upon Harry.

“Hmpf,” he said, looking away quickly as though frightened of hurting his eyes. “Here —” He gave a drink to Dumbledore, who had sat down without invitation, thrust the tray at Harry, and then sank into the cushions of the repaired sofa and a disgruntled silence. His legs were so short they did not touch the floor.

“Well, how have you been keeping, Horace?” Dumbledore asked.

“Not so well,” said Slughorn at once. “Weak chest. Wheezy. Rheumatism too. Can’t move like I used to. Well, that’s to be expected. Old age. Fatigue.”

“And yet you must have moved fairly quickly to prepare such a welcome for us at such short notice,” said Dumbledore. “You can’t have had more than three minutes’ warning?”

Slughorn said, half irritably, half proudly, “Two. Didn’t hear my Intruder Charm go off, I was taking a bath. Still,” he added sternly, seeming to pull himself back together again, “the fact remains that I’m an old man, Albus. A tired old man who’s earned the right to a quiet life and a few creature comforts.”

He certainly had those, thought Harry, looking around the room. It was stuffy and cluttered, yet nobody could say it was uncomfortable; there were soft chairs and footstools, drinks and books, boxes of chocolates and plump cushions. If Harry had not known who lived there, he would have guessed at a rich, fussy old lady.

“You’re not yet as old as I am, Horace,” said Dumbledore.

“Well, maybe you ought to think about retirement yourself,” said Slughorn bluntly. His pale gooseberry eyes had found Dumbledore’s injured hand. “Reactions not what they were, I see.”

“You’re quite right,” said Dumbledore serenely, shaking back his sleeve to reveal the tips of those burned and blackened ringers; the sight of them made the back of Harry’s neck prickle unpleasantly. “I am undoubtedly slower than I was. But on the other hand…”

He shrugged and spread his hands wide, as though to say that age had its compensations, and Harry noticed a ring on his uninjured hand that he had never seen Dumbledore wear before: It was large, rather clumsily made of what looked like gold, and was set with a heavy black stone that had cracked down the middle. Slughorn’s eyes lingered for a moment on the ring too, and Harry saw a tiny frown momentarily crease his wide forehead.

“So, all these precautions against intruders, Horace… are they for the Death Eaters’ benefit, or mine?” asked Dumbledore.

“What would the Death Eaters want with a poor broken-down old buffer like me?” demanded Slughorn.

“I imagine that they would want you to turn your considerable talents to coercion, torture, and murder,” said Dumbledore. “Are you really telling me that they haven’t come recruiting yet?”

Slughorn eyed Dumbledore balefully for a moment, then muttered, “I haven’t given them the chance. I’ve been on the move for a year. Never stay in one place more than a week. Move from Mug-gle house to Muggle house — the owners of this place are on holiday in the Canary Islands — it’s been very pleasant, I’ll be sorry to leave. It’s quite easy once you know how, one simple Freezing Charm on these absurd burglar alarms they use instead of Sneako-scopes and make sure the neighbors don’t spot you bringing in the piano.”

“Ingenious,” said Dumbledore. “But it sounds a rather tiring existence for a broken-down old buffer in search of a quiet life. Now, if you were to return to Hogwarts —”

“If you’re going to tell me my life would be more peaceful at that pestilential school, you can save your breath, Albus! I might have been in hiding, but some funny rumors have reached me since Dolores Umbridge left! If that’s how you treat teachers these days —”

“Professor Umbridge ran afoul of our centaur herd,” said Dumbledore. “I think you, Horace, would have known better than to stride into the forest and call a horde of angry centaurs ‘filthy half-breeds.’”

“That’s what she did, did she?” said Slughorn. “Idiotic woman. Never liked her.”

Harry chuckled and both Dumbledore and Slughorn looked round at him.

“Sorry,” Harry said hastily. “It’s just — I didn’t like her either.”

Dumbledore stood up rather suddenly.

“Are you leaving?” asked Slughorn at once, looking hopeful.

“No, I was wondering whether I might use your bathroom,” said Dumbledore.

“Oh,” said Slughorn, clearly disappointed. “Second on the left down the hall.”

Dumbledore strode from the room. Once the door had closed behind him, there was silence. After a few moments, Slughorn got to his feet but seemed uncertain what to do with himself. He shot a furtive look at Harry, then crossed to the fire and turned his back on it, warming his wide behind.

“Don’t think I don’t know why he’s brought you,” he said abruptly.

Harry merely looked at Slughorn. Slughorn’s watery eyes slid over Harry’s scar, this time taking in the rest of his face.

“You look very like your father.”

“Yeah, I’ve been told,” said Harry.

“Except for your eyes. You’ve got —”

“My mother’s eyes, yeah.” Harry had heard it so often he found it a bit wearing.

“Hmpf. Yes, well. You shouldn’t have favorites as a teacher, of course, but she was one of mine. Your mother,” Slughorn added, in answer to Harrys questioning look. “Lily Evans. One of the brightest I ever taught. Vivacious, you know. Charming girl. I used to tell her she ought to have been in my House. Very cheeky answers I used to get back too.”

“Which was your House?”

“I was Head of Slytherin,” said Slughorn. “Oh, now,” he went on quickly, seeing the expression on Harry’s face and wagging a stubby ringer at him, “don’t go holding that against me! You’ll be Gryffindor like her, I suppose? Yes, it usually goes in families. Not always, though. Ever heard of Sirius Black? You must have done — been in the papers for the last couple of years — died a few weeks ago —”

It was as though an invisible hand had twisted Harry’s intestines and held them tight.

“Well, anyway, he was a big pal of your father’s at school. The whole Black family had been in my House, but Sirius ended up in Gryffindor! Shame — he was a talented boy. I got his brother, Regulus, when he came along, but I’d have liked the set.”

He sounded like an enthusiastic collector who had been outbid at auction. Apparently lost in memories, he gazed at the opposite wall, turning idly on the spot to ensure an even heat on his backside.

“Your mother was Muggle-born, of course. Couldn’t believe it when I found out. Thought she must have been pure-blood, she was so good.”

“One of my best friends is Muggle-born,” said Harry, “and she’s the best in our year.”

“Funny how that sometimes happens, isn’t it?” said Slughorn.

“Not really,” said Harry coldly.

Slughorn looked down at him in surprise. “You mustn’t think I’m prejudiced!” he said. “No, no, no! Haven’t I just said your mother was one of my all-time favorite students? And there was Dirk Cresswell in the year after her too — now Head of the Goblin Liaison Office, of course — another Muggle-born, a very gifted student, and still gives me excellent inside information on the goings-on at Gringotts!”
