Darrell Rivers is the main character of the first six books. Although responsible and hard-working, her hot temper causes her problems, but she learns to control it as she goes up the school. She is very popular with her form. In the upper school she becomes Head of the Fourth Form, games captain in the Fifth and finally, in the Sixth Form, Head Girl of the school. As she gets older at Malory Towers she begins to realise her talent for writing and aspires to be a writer in her adult career. The Malory Towers girls, minus Darrell and Sally, go on a school field tip. Gwen has promised ices to everyone, but when her and Mary-Lou accidentally miss the bus they must join Darrell and Sally performing various tasks around the school to better everything. The tasks may provide Gwen a chance to find a good hiding place for her stolen goods, or it may result in her getting caught and punished for good, but they also provide Darrell and Sally the opportunity to figure out where Lady Malory's hidden treasure might be so they can save the school. New girls Darrell Rivers, Sally Hope and Gwendoline Mary Lacey arrive for their first day at Malory Towers, their new school on a clifftop location above an idyllic coastline. They meet Miss Grayling, the wise and dignified headmistress, no-nonsense First Form mistress Miss Potts, and the stern Matron. Gwendoline hopes that she and Darrell will be best friends, but is due for an unpleasant surprise.

Geneviève Beaudet as Mam’Zelle Rougier, the French teacher at Malory Towers. She is strict and hyper-critical, but later gets better and listening and interacting. In addition to teaching, she oversees the girls when they reach the Fourth Form as their mistress. The new girls are received by the headmistress, who tells them: ‘One day you will leave school & go out into the world as young women. You should take with you eager minds, kind hearts, & the will to help. You should take with you a good understanding of many things & a willingness to accept responsibility & a willingness to show yourselves as women to be loved & trusted. All these things you will be able to learn @ Malory Towers - if you will. I do not count as our successes those who have won scholarships & passed exams, tho’ these are good things to do. I count as our successes those who learn to be good-hearted & kind, sensible & trustable, good sound women the world can lean on. Our failures are those who do not learn thee things in the years they are here.’Miss Potts is the First Form mistress and House Mistress of North Tower. She is strict and always has an eye on mischief-makers such as Alicia and June. She saw a big, square looking building of soft grey stone standing high up on a hill. The hill was really a cliff, that fell steeply down to the sea. At each end of the gracious building stood rounded towers. Darrell could glimpse other towers as well, making four in all. North Tower, South, East and West. Ivy is one of Daffy's followers and friends. Her personality is described to be blunt, forthright and outspoken. From the formidable Miss Potts we are then introduced to Alicia Johns, a girl in Darrell’s form who has been at Malory Towers for some time (though we are not told how many terms Alicia has been at the school). Darrell takes an instant liking to Alicia, hoping that this older girl will be her special friend. Form 1. “Mam’zelle, excuse my interrupting you, but is it necessary for the girls to repeat their French lesson so very loudly?” she asked. “Ah, Miss Potts, I am so sorry. But it is not for me the girls repeat words so loudly, it is for the poor Alicia,” explained Mam’zelle. Miss Potts looked most surprised. She looked at Alicia. Alicia felt uncomfortable. She also looked as innocent as she could. But Miss Potts was always on the alert when Betty or Alicia looked innocent. “What do you mean, Mam’zelle?” she snapped. “Has Alicia suddenly gone deaf? She was all right this morning.” “She is quite, quite deaf now,” Mam’zelle assured her. Miss Potts looked sharply at Alicia. “Come to me at Break, Alicia,” she said. “I would like a few words with you.” Nobody dared repeat these words to Alicia, but Mam’zelle herself obliged. She shouted across to Alicia. “Miss Potts says, will you . . .” “Don’t bother to repeat what I said, Mam’zelle,” said Miss Potts. “Alicia will come all right. I shall expect you at eleven, Alicia. And please stand up when I speak to you.” Alicia stood up, her face a flaming red. Miss Potts went out of the room, and she did not shut the door very quietly. Mam’zelle disliked people who banged doors. “Ah, this door, it goes through my poor head!” she said. “Miss Potts, she is very good and clever, but she does not have the head-ache, as I do . . .” “Nor the ear-ache,” put in Darrell, but no one raised a giggle. Miss Potts’s entry and fierceness had damped the cheerfulness of the class considerably. Alicia said no more about her ear-ache. She took a book and sat down by the window in the sunshine, feeling sure that Miss Potts would not appear again. She thought she might as well get something out of her performance! Mam’zelle took no further notice of her, and devoted herself to a whole- hearted search for someone in Form 1 who could and would conjugate a whole French verb properly. Not finding anyone really good, she lost the good temper she had entered with that morning, and gave the class a bad time. She stalked out when the bell for Break went. The girls crowded round Alicia. “Oh, Alicia! I nearly died when you said ‘beer’.”—“Wasn’t it a shame Potty coming in like that?”—“Will you get into a fearful row, Alicia?” “Darrell nearly yelled the roof off!” said Irene. “I almost burst with trying not to laugh.” “I must go and hear what Potty has to say,” said Alicia. “Pity I forgot she was taking Form 2 next door! So long, girls!”
