Darrell's career from this point is smoother, and she eventually covers herself in the personal, scholastic and sporting glory that was originally expected of her. She is head of the fourth form, games captain of the fifth, and head girl in her final year as well as being a successful lacrosse and tennis player. When she is in the fourth form, her younger sister, Felicity, joins her as a first former at the school. From then up until "Last Term at Malory Towers", we also focus on Felicity and the rest of her form, especially June, the troublesome cousin of Alicia. In all of the books, Darrell plays a pivotal role, though she is not always successful in her endeavours and indeed is temporarily stripped of her fourth-form captaincy (when she is caught shaking a smaller girl (June) who was threatening to reveal the secret of a midnight feast held by the fourth formers out of personal spite), though she gets it back again by resolving a particularly complicated case of sibling rivalry. She is on friendly terms with most of her classmates and even makes her peace with Gwendoline Lacey at the end, when a personal tragedy strikes the vain, selfish class outcast.
