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 who was born on this day in 1920.
