In his seventh appearance, Fox—always a bit too clever for his own good—gets three more just deserts: when he cheats by using little sister Louise as the engine of his homemade race car; when a neighbor gleefully absconds with the beloved comics he has mendaciously disparaged; and when Louise, abandoned in her Halloween pumpkin costume by the older kids, renders some delightfully novel and appropriate poetic justice. Illustrations limned with Marshall's usual zest and verve; good comical fun. (Easy reader. 4-8)
