The Mischief by Assia Djebar

It was written and first published in French in the mid-50’s, and is set over the course of a single summer. Its heroine is one of the jeunesse dorée, dissatisfied and bored despite her wealth and privilege. She drives a fast sports car, and idles away her days sunbathing on Mediterranean beaches and flirting with her boyfriend. She’s a capricious enfant terrible, and she’s stricken with jealousy at the happiness of a couple close to her, so she amuses herself by sabotaging their relationship, with unexpectedly tragic consequences. ~ Lucy Scholes, The Paris Review
