Robin Stevens' Jolly Foul Play
I LOVE Stevens' Wells and Wong series, and this fourth one was just as delightful as the other three. The girls are back at their boarding school (the series is set in England in the 1930s), now under the reign of a terror of a Head Girl--when said Head Girl is MURDERED, by one of her prefects! Of course Daisy and Hazel are on the case, with the assistance of their dorm-mates and a certain pen pal. I love the focus here on female friendships and find these characters super likable and interesting. Plus really solid mystery plotting! I wish Stevens would write four more of these immediately. A/A-.
