“Who’s Professor Slughorn?” asked Neville, looking perplexedly at his own invitation.
“New teacher,” said Harry. “Well, I suppose we’ll have to go, won’t we?”
“But what does he want me for?” asked Neville nervously, as though he was expecting detention.
“No idea,” said Harry, which was not entirely true, though he had no proof yet that his hunch was correct. “Listen,” he added, seized by a sudden brain wave, “let’s go under the Invisibility Cloak, then we might get a good look at Malfoy on the way, see what he’s up to.”
This idea, however, came to nothing: The corridors, which were packed with people on the lookout for the lunch trolley, were impossible to negotiate while wearing the Cloak. Harry stowed it regretfully back in his bag, reflecting that it would have been nice to wear it just to avoid all the staring, which seemed to have increased in intensity even since he had last walked down the train. Every now and then, students would hurtle out of their compartments to get a better look at him. The exception was Cho Chang, who darted into her compartment when she saw Harry coming. As Harry passed the window, he saw her deep in determined conversation with her friend Marietta, who was wearing a very thick layer of makeup that did not entirely obscure the odd formation of pimples still etched across her face. Smirking slightly, Harry pushed on.
When they reached compartment C, they saw at once that they were not Slughorn’s only invitees, although judging by the enthusiasm of Slughorn’s welcome, Harry was the most warmly anticipated.
“Harry, m’boy!” said Slughorn, jumping up at the sight of him so that his great velvet-covered belly seemed to fill all the remaining space in the compartment. His shiny bald head and great silvery mustache gleamed as brightly in the sunlight as the golden buttons on his waistcoat. “Good to see you, good to see you! And you must be Mr. Longbottom!”
Neville nodded, looking scared. At a gesture from Slughorn, they sat down opposite each other in the only two empty seats, which were nearest the door. Harry glanced around at their fellow guests. He recognized a Slytherin from their year, a tall black boy with high cheekbones and long, slanting eyes; there were also two seventh-year boys Harry did not know and, squashed in the corner beside Slughorn and looking as though she was not entirely sure how she had got there, Ginny.
“Now, do you know everyone?” Slughorn asked Harry and Neville. “Blaise Zabini is in your year, of course —”
Zabini did not make any sign of recognition or greeting, nor did Harry or Neville: Gryffindor and Slytherin students loathed each other on principle.
“This is Cormac McLaggen, perhaps you’ve come across each other — ? No?”
McLaggen, a large, wiry-haired youth, raised a hand, and Harry and Neville nodded back at him.
“— and this is Marcus Belby, I don’t know whether — ?”
Belby, who was thin and nervous-looking, gave a strained smile.
“— and this charming young lady tells me she knows you!” Slughorn finished.
Ginny grimaced at Harry and Neville from behind Slughorn’s back.
“Well now, this is most pleasant,” said Slughorn cozily. “A chance to get to know you all a little better. Here, take a napkin. I’ve packed my own lunch; the trolley, as I remember it, is heavy on licorice wands, and a poor old man’s digestive system isn’t quite up to such things. . . . Pheasant, Belby?”
Belby started and accepted what looked like half a cold pheasant.
“I was just telling young Marcus here that I had the pleasure of teaching his Uncle Damocles,” Slughorn told Harry and Neville, now passing around a basket of rolls. “Outstanding wizard, outstanding, and his Order of Merlin most well-deserved. Do you see much of your uncle, Marcus?”
Unfortunately, Belby had just taken a large mouthful of pheasant; in his haste to answer Slughorn he swallowed too fast, turned purple, and began to choke.
“Anapneo,” said Slughorn calmly, pointing his wand at Belby, whose airway seemed to clear at once.
“Not . . . not much of him, no,” gasped Belby, his eyes streaming.
“Well, of course, I daresay he’s busy,” said Slughorn, looking questioningly at Belby. “I doubt he invented the Wolfsbane Potion without considerable hard work!”
“I suppose . . .” said Belby, who seemed afraid to take another bite of pheasant until he was sure that Slughorn had finished with him. “Er . . . he and my dad don’t get on very well, you see, so I don’t really know much about . . .”
His voice tailed away as Slughorn gave him a cold smile and turned to McLaggen instead.
“Now, you, Cormac,” said Slughorn, “I happen to know you see a lot of your Uncle Tiberius, because he has a rather splendid picture of the two of you hunting nogtails in, I think, Norfolk?”
“Oh, yeah, that was fun, that was,” said McLaggen. “We went with Bertie Higgs and Rufus Scrimgeour — this was before he became Minister, obviously —”
“Ah, you know Bertie and Rufus too?” beamed Slughorn, now offering around a small tray of pies; somehow, Belby was missed out. “Now tell me . . .”
