History Literature / TheHauntingOfDrearcliffGrangeSchool

* CharacterOverlap: Several of the characters have previously appeared in the ''Literature/DiogenesClub'' series. Amy herself has been mentioned a few times in her adult guise as a moth-themed costumed crimefighter, including a cameo in "Literature/SorcererConjurerWizardWitch". Fish-girl Janice Marsh, as an adult, is a key character in "The Big Fish" and "Another Fish Story". Miss Borrodale, the science teacher, appears as a schoolgirl in "Richard Riddle, Boy Detective in 'The Case of the French Spy'". Geoffrey Jeperson is the father of Richard Jeperson, one of the main protagonists of the Diogenes series. "Clever Dick" Cleaver from "Literature/ClublandHeroes" makes a cameo appearance.

''The Haunting of Drearcliff Grange School'' is a novel by Creator/KimNewman, and sequel to ''Literature/TheSecretsOfDrearcliffGrangeSchool''. It's a homage to the girls' BoardingSchool adventure stories of the early twentieth century, with a fantasy twist: Drearcliff Grange is a school for girls who are ... ''unusual''.

* PrehensileHair: Sterlyng ''emulates'' this trope with her whip-length, hook-laced braid of hair, although it's unclear to what extent she has control over her coiffure-cum-weapon's movement.

* SeriesContinuityError: When Knowles mentions that people with psychic abilities have an increased chance of developing a brain aneurysm, Amy says that so far her powers haven't so much as given her a nosebleed. The first book in the series said that when Amy's telekinesis was first developing, trying to use it gave her a nosebleed more often than not. (Maybe she's just forgotten what it used to be like now that it's fully under her control, or maybe she only got nosebleeds if she tried to ''force'' her powers to work before they became reliable. Or maybe Amy is merely affronted that ''Knowles'' has never gotten them like Amy used to.)

** One of the girls had a picture book published by Uncle Satt, the children's story publisher with murky origins featured in "Literature/TheGypsiesInTheWood". A Sir Bruin de Bear toy, based on one of the characters in Uncle Satt's stories, is also mentioned.

* ShoutOut:
** The rumor about the Black Sow that lurks in "Under-London" is a nod to the Beast of London Below in ''Literature/{{Neverwhere}}''.
** One of the locations in the scavenger hunt is [[Literature/{{Dracula}} Count Dracula's now-abandoned London residence]]. Among the inexplicable rubbish scattered about the place is [[Film/Dracula1931 the long-dried-out shell of an armadillo]].
** Another of the locations is Literature/SherlockHolmes themed: it's the location of the [[Literature/AStudyInScarlet first murder Holmes and Watson investigated together]], and the item to be retrieved is disguised in the manner of the macguffin in "The Six Napoleons".
** Another Literature/SherlockHolmes reference: Moria Kratides is the daughter of Sophy Kratides from "The Greek Interpreter".
** When Knowles is recounting what she's learned about the history of the Broken Doll, part of it is an untold adventure of Literature/CarnackiTheGhostFinder.
** Knowles uses an Electric Pentacle, Carnacki's signature protective device, in the confrontation at the Music Room, and it proves capable of suppressing the telekinetic powers of both Amy and the Broken Doll.
