By the time Halloween arrived, Hogwarts had learned how to be noisy in layers.
There was the ordinary noise of school, footsteps, doors, voices crossing in corridors, the scrape of benches, the distant irritation of Peeves. Then there was Halloween noise, brighter and more deliberate. The castle had been dressed for it with the confidence of something old enough to find seasonal theatrics beneath its dignity and permit them anyway. Great orange pumpkins floated near the ceiling in the Great Hall. Candles burned lower and warmer than usual. Decorations had appeared overnight in alcoves and over doorways. The suits of armour seemed faintly smug.
Even the air smelled different.
Roast pumpkin, nutmeg, wax, polished wood, damp stone, and a sweetness from the kitchens that made first-years walk faster without always knowing why.
At breakfast, Stephen informed the Ravenclaw table that Halloween at Hogwarts was supposed to be "historically significant."
"Historically significant how?" Michael asked.
Stephen shrugged. "Old, I assume."
"That applies to most things here."
Anthony, who had spent the morning staring thoughtfully at one of the floating pumpkins, said, "I think the decorations are excessive on purpose."
Michael put down his spoon. "Explain."
"So the castle can tell who is new."
There was a pause.
Then Michael said, "No."
Adrian said nothing.
He had learned that when Anthony sounded absurd, it was worth waiting half a minute before dismissing him. Not because Anthony was usually correct. He was not. But because his mind moved through associations that occasionally struck truth from the side.
The day itself passed in the usual sequence of classes, though no one treated it entirely as usual. Attention frayed more easily. Even Hermione Granger seemed only partly committed to absolute academic vigilance in Charms, and that was saying something. Students had an unfortunate tendency to behave as if feasts later in the day justified incompetence earlier in it.
By late afternoon, the corridors had changed texture. More students than usual drifted in groups rather than hurrying directly between destinations. Laughter carried farther. A pair of second-years tried to charm a pumpkin into singing and were caught by Professor Flitwick, who was disappointed enough to be genuinely dangerous.
Adrian spent part of the hour before the feast in the library, then abandoned the attempt at reading when even Madame Pince looked resigned to disorder. On the way back toward Ravenclaw Tower, he crossed paths with Harry Potter, Ron Weasley, and Hermione Granger near the foot of a staircase.
It was not a meeting. Barely even an encounter.
Hermione was walking ahead of the boys with her books held too tightly and her chin lifted in the way people do when they are trying to preserve dignity through sheer angle. Ron was red with the aftermath of saying something he had not intended to hurt quite so much. Harry looked caught between loyalty and discomfort, which suited him poorly.
They passed Adrian without really seeing him.
That was ordinary enough.
What was less ordinary was the sensation that lingered after. Not theirs. His.
Tension had weight. Not magical, perhaps, but enough to anchor memory more firmly than most passing moments did. Adrian knew at once that he would remember Hermione's expression later, though he had no direct part in it. Hurt gave edges to things.
He went on.
By evening the Great Hall glowed.
The Halloween feast was larger than the ordinary dinners, as if the castle had reached into some older idea of celebration and found moderation insulting. The floating pumpkins were lit from within now, their carved faces ranging from cheerful to frankly unwell. Bats fluttered high above the tables. Candles gleamed in long lines of wax and gold.
Ravenclaw had settled into its usual conversational pattern around him, which meant three discussions at once and a fourth implied. Michael was disputing some point of wand safety with a girl from fifth year. Anthony was examining a pumpkin tart as if expecting a coded message. Stephen had taken enough food for two boys and saw no contradiction in this.
Adrian was halfway through a serving of roast chicken when the doors of the Great Hall burst open.
Professor Quirrell stumbled in.
His turban was crooked. His face had gone a colour usually associated with weakened paper. He lurched toward the centre of the hall, one hand out as though the air itself were unreliable.
"Troll," he gasped. "In the dungeons. Thought you ought to know."
Then he collapsed.
For one perfect second, the entire hall held still.
Then sound broke over everything at once.
Students shouted. Benches scraped. A Hufflepuff near the door screamed. Someone laughed from sheer nerves and then stopped when no one joined in. The floating pumpkins bobbed faintly, ridiculous in the middle of it all.
Adrian did not move.
He watched Quirrell.
Specifically, he watched the interval between the announcement and the collapse.
Fear was difficult to fake completely. But reaction could be arranged around it. Quirrell's voice had been wrong. Not too panicked. Too placed. As if he had selected the precise amount of public terror required before dropping.
At the staff table, Professor Snape was already on his feet.
That was interesting too.
Not delayed. Not shocked. Moving.
Dumbledore rose and amplified his voice over the uproar with enough calm to make panic feel childish by comparison.
"Prefects," he called, "lead your Houses back to the dormitories immediately."
The order took hold with predictable imperfection. Students surged, corrected, re-formed. Prefects shouted themselves hoarse. Chairs toppled. The teachers moved quickly but not all in the same direction. McGonagall was all command. Flitwick herded terrified first-years with unexpected force. Snape had vanished from the staff table almost before the sound fully broke.
Quirrell, meanwhile, had not yet been removed.
Adrian rose with Ravenclaw and let himself be pulled into the current moving toward the doors.
The hall was all momentum now. Clusters formed and broke. One second-years' prefect kept repeating, "Stay together," with the brittle optimism of someone who had never met eleven-year-olds in a crisis. Anthony nearly walked into a suit of armour because he was looking back at the staff table. Michael dragged him straight without comment.
Adrian looked back too.
Quirrell was being helped up by another professor. His face still wore alarm. His body, though, had steadied too quickly. Not entirely. Enough.
A staged collapse, then? Or one only partly real?
He filed the thought and kept walking.
The corridors outside the Great Hall were worse. Noise echoed. Students who had not been at the feast were demanding explanations from those who had, and the explanations grew less accurate by the second.
"It was loose in the Hall."
"No, in the dungeons."
"They said it ate someone."
"It didn't."
"Are you sure?"
"No."
Perfect.
Panic did what panic always did. It shattered sequence. Made people poor witnesses.
Adrian let Ravenclaw's flow carry him toward the tower route, then slowed at a junction while a crush of older students swept past. No one noticed immediately. That, too, was instructive.
From where he stood, half-shadowed between a torch bracket and a statue with no nose, he could see three directions of movement at once. Ravenclaws upward. Hufflepuffs pushing toward the lower corridors before being corrected. A pair of Slytherins trying and failing to look unconcerned.
Then Snape crossed the far corridor at speed.
Not running. Snape would likely consider that a failure of breeding. But moving fast enough that purpose overtook dignity. His robes snapped behind him. His face was tight, not with fear, but with concentration sharpened by anger.
He was not going to the dungeons.
That struck Adrian with clean certainty.
The troll had been announced in the dungeons. Snape was moving toward the upper corridors, angling, if Adrian judged the route correctly, toward the section of the castle that led eventually to the third-floor passage Harry Potter had once been told to avoid.
A piece clicked into place.
Not the whole pattern. Enough of one.
Quirrell had announced danger below.
Snape had gone above.
Which meant one of them was lying about what mattered.
The moment lasted perhaps two seconds.
Then a Ravenclaw sixth-year appeared at Adrian's elbow like civic wrath in human form. "Why are you standing here?"
"Observing."
"That was not a sincere answer. Move."
He moved.
Back in Ravenclaw Tower, the common room had taken on the agitated brightness of forced safety. Students clustered in nervous groups. The bronze eagle on the door had apparently been told the password question was suspended, which Anthony found philosophically offensive. First-years sat where older students told them. Everyone talked at once.
Troll.
In the dungeons.
In the girls' lavatory.
Two trolls.
A mountain troll.
No one knew anything. Everyone had a version.
Adrian stood near the fire listening.
The useful thing about frightened people was that they often supplied structure accidentally while trying to invent it. Names repeated. Locations drifted. Timings contradicted one another, and contradiction itself became informative.
Hermione Granger's name did not come up.
That mattered.
If she had been at the feast, someone would have mentioned her, if only in the ordinary orbit around Harry and Ron. The absence was small, but once noticed it remained.
He turned slightly.
Harry Potter and Ron Weasley were not in Gryffindor yet either. That, too, would matter soon, once someone began counting properly.
He had just reached that conclusion when the common room door opened again to admit a late pair of Ravenclaws and a gust of colder air.
The bronze eagle said, in a tone of dry injury, "I do not see why emergencies should excuse ignorance."
No one paid attention.
Adrian crossed to the window. From this height the grounds were mostly dark. A few lit windows cut other towers into shape against the night. Somewhere below, the castle continued moving around the panic, carrying it, redirecting it, absorbing it into old stone.
He imagined the Gryffindor common room at that moment. Harry absent. Ron absent. Hermione unaccounted for. Percy Weasley discovering it in some order likely to make him unwell.
Interesting, yes.
Also dangerous.
Adrian did not leave the tower.
That mattered too.
He could have tried. The corridors would be chaos enough to attempt almost anything. But Harry and Ron were already involved, if his reasoning was sound, and when Harry Potter moved toward danger the outcome tended to rearrange itself around him. Intervening blindly in that sort of structure was not strategy. It was vanity.
So he stayed where he was and listened.
Time passed badly.
At last, well after the first wave of panic had dulled into rumour and waiting, word filtered upward in broken pieces.
The troll had been found.
It had not killed anyone.
There had been students involved.
Three students, maybe. No, two. No, Granger had been there. Yes, Potter and Weasley too. No one entirely knew how or why, only that Professor McGonagall had looked furious enough to charm wallpaper off the stone and that points had been awarded or removed or both depending on who told it.
By the time the structure of it became clearer, the fire had burned low.
Harry Potter and Ron Weasley had gone after Hermione Granger.
The troll had been in the girls' lavatory, not the dungeons.
Quirrell's announcement had been true only in the least useful sense.
Adrian sat down at one of the side tables and opened his notebook.
Halloween. Quirrell announces troll in dungeons. Panic immediate. Snape heads toward upper corridors, not lower. Hermione absent from feast. Potter and Weasley also unaccounted for. Troll later found in girls' lavatory.
He paused, then added:
Quirrell's fear inconsistent. Snape's urgency directed elsewhere.
There it was. The line he had been approaching all evening without naming.
The school believed, broadly speaking, that Snape was dangerous and Quirrell was weak.
Adrian was beginning to suspect the opposite arrangement was more useful.
Not because Snape was harmless. He was clearly not. But because his hostility pointed somewhere specific. Quirrell's weakness, on the other hand, had edges that moved when observed.
Across the room, Anthony lowered the book he had been pretending to read for at least ten minutes.
"You're writing as if something interesting happened."
Adrian closed the notebook. "Something did."
Anthony considered this. "Do you think the troll was the important part?"
"No," Adrian said.
Anthony looked faintly pleased, as if the answer had confirmed a private theory.
Later, after the tower had finally quieted and the dormitory curtains had begun whispering shut one by one, Adrian lay awake longer than usual.
Below him, through layers of stone and distance, Hogwarts continued in all its old, unseen routes. Teachers moving. Doors opening. Portraits gossiping. Secrets going from hand to hand in forms no one would ever quite record correctly.
A troll in the castle should have been the night's central fact.
It was not.
The central fact was misdirection.
And the more Adrian thought about Quirrell collapsing in the Great Hall, Snape moving elsewhere, and the troll appearing precisely where it would attract chaos rather than purpose, the less accidental any of it seemed.
He turned onto his side and looked toward the gap in the curtains where moonlight thinned itself against the dormitory floor.
Someone in this school had tried to move attention.
The troll was only the blunt instrument.
The real event had happened somewhere else.
