The Rebel of the School by L.T. Meade

So the head-mistress had written; she had dared to write to Kathleen's father. What she said to him was a matter of no moment; she had written, and to complain of her!

"She thinks, I suppose," said Kathleen, "that she'll subdue me by these means. She wants to bring, not the long arm of the law, but father's arm right across the sea to stop me. No, no, daddy, your Kathleen will be your Kathleen to the end -- always loving, always daring, always true, but always rebellious; the best and the worst. I am going to-night, and I am going all the more surely because you wired to me not to go, and because they are daring to bully dear little Ruth Craven. And after I have had my fling I will come back in good time. No fear; nothing will go wrong. Your Kathleen wouldn't hurt a fly, much less your heart. But I mean to have my fun to-night."
