"A St. Trinian’s girl would be sadistic, cunning, dissolute, crooked, sordid, lacking morals of any sort and capable of any excess. She would also be well-spoken, even well-mannered and polite. Sardonic, witty and very amusing. She would be good company. In short: typically human and, despite everything, endearing."
— Ronald Searle (St. Trinian's: The Entire Appalling Business)
