“Alan Bradley’s third Flavia de Luce mystery, A Red Herring Without Mustard, exceeds in every way, if that’s even possible, his first two. Flavia uses her trademark cunning by scheming to get even with her older sisters, who lay in wait to torment her. She saves a Gypsy’s life, befriends Porcelain, the Gypsy’s granddaughter, solves a puzzling and bizarre murder involving an ancient nonconformist cult, collects clues the police have missed, and fearlessly ventures into danger. She is always feisty, always smart. I adore her. And while it is wonderful to read her as an adult, I wish I’d had Flavia as a role model while growing up. It’s cool to be smart. It’s cool to be Flavia! And it’s great to be among her legion of fans.”
