"Harry was at the point of telling Ron and Herminone about Filch and Kwikspell course when the salamander suddenly whizzed into the air, emmitting loud sparks and bangs as it whirled wildly round the roonm. The sight of Percy bellowing himslef hoarse at Fred and George, the spectacular display of tangerine stars showering from the salamander's mouth, and its escape into the fire, with accompanying explosions, drove both Flich and the Kwikspell envelope from Harry's mind. By the time Halloween arrived, Harry was regretting his rash promise to go to the deathday party. The rest of the school was happily anticipating their Halloween feast." "The Great Hall had been decorated with the usual live bats, Hagrid's vast pumpkins had been carved into lanterns large enough for three men to sit in and there were rumors that Dumbledore had booked a troupe of dancing skeletons for the entertainment.""A promise is a promise", Herminone reminded Harry bossily." You said you'd go to the deathday party." So at seven o'clock, Harry, Ron, and Hermione walked straight past the doorway to the packed Great Hall, which was flittering invitingly with gold plates and candles, and directed their steps instead towards the dungeons." "The passageway leading to Nearly Headless Nick's party had been lined with candles, too, through the effect was far from cheerful: These were long, thin, jet-black tapers, all burning bright blue, casting a dim, ghostly light even over their own living faces. The temperature dropped with every step they took. As Harry shivered and drew his robes tightly around him, he heard what sounded like a thousand findernails scraping an enormous blackboard."
"Is that supposed to be music?" Ron whispered. They turned a corner and saw Nearly Headless Nick standing at a doorway hung with black velvet drapes. "My dear friends." he said mournfully. "Welcome, welcome . . so pleased you could come . . ." He swept off his plumed hat and bowed them inside. It was an incredible sight. the dungeon was full of hundreds of pearly-white, translucent people, mostly drifiting around a crowded dance floor, waltzing to the dreadful, quavering sound of thrity musical saws, played by an orchestra on a raised, black-draped platform." "A chandelier overhead blazed midnight-blue with a thousand more black candles. Their breath rose in a mist before them; it was like stepping into a freezer. "Shall we have a look around?" Harry suggested, wanting to warm up his feet. "Careful not to walk through anyone," said Ron nervously and they set off around the edge of the dance floor. They passed a group of gloomy nuns, a ragged man wearing chains, and the Fat Friar, a cheerful Hufflepuff ghost, who was talking to a knight with an arrow sticking out of his forehead." "Harry wasn't surprised to see that the Bloody Baron, a gaunt, staring Slytherin ghost covered in silver bloodstains, was being given a wide berth by the other ghosts." "Oh, no," said Herminone, stopping abruptly. "Turn back, turn back, I don't want to talk to Moaning Myrtle -"Who?" said Harry as they backtracked quickly. "She haunts one of the toilets in the girls' bathroom on the first floor,"said Hermione."
"The rest of Harry's sentence was drawned out by a high-pitched mewling from somewhere near his ankles. He looked down and found himself gazing into a pair of lamp-like yellow eyes. It was Mrs. Norris, the skeletal gray cat who was used by the caretaker, Argus Filch, as a sort of deputy in his endless battle against students." "You'd better get out of here, Harry," said Nick quickly. "Filch isn't in a good mood - he's got the flu and some third years accidentally plastered frog brains all over the ceiling in dungeon five. He's been cleaning all morning, and if he sees you dripping mud all over the place -" "Right," said Harry, backing away from the accusing stare of Mrs. Norris, but not quickly enough. Drawn to the spot by the mysterious power that seemed to connect him with his foul cat, Argus Filch burst suddenly through a tapestry to Harry's right, wheezing and looking wildly about for the rulebreaker. There was a thick tartan scarg bound around his head, and his nose was unusally purple." "Filth!" he shouted, his jowls aquiver, his eyes popping alarmingly as he pointed at the muddy puddle that had dripped from Harry's Quidditch robes. "Mess and muck everywhere! I've had enough of it, I tell you! Follow me, Potter!" So Harry waved a gloomy good-bye to Nearly Headless Nick and followed Filch back downstairs, doubling the number of muddy footprints on the floor. Harrry had mever been inside Filch's office before; it was a place most students avoided. the room was dingy and windowless, lit by a single oil lamp dangling from the low ceiling." - Harry Potter and The Chamber of Secrets
