Oh boy, another Christie! This is a recommendation from Emily, a short story with a satisfying love triangle. And a nice little easy read after several weeks in a row of full novels.
Cotillion by Georgette Heyer
More of a comic farce than a romance novel, really shows what made Heyer special, her talent for dialogue and building characters and writing real true novels, not just little romances. It’s fun, it’s an easy read, and it’s easy to get your hands on!
“the Soul of the Croupier” by Agatha Christie
A short story, in various collections by her. Fun setting in Monte Carlo, fun little mystery, and not so well-known that you already know the ending.
