Not only the cat, but a classroom rat, a police dog, assorted birds, rodents, goldfish, and a gang of penguins get carried away in this fast-paced mystery for newly independent readers. Unlikely and seemingly unrelated events collide during two momentous days in the life of the Gaskitt family. Animals are disappearing all over town, a strange man is rushing through the streets steering an old baby carriage, and Mrs. Gaskitt is confined to her bed, eating pineapple and fried egg sandwiches. Meanwhile, a fitness-crazed substitute teacher is running the Gaskitt twins into the ground, literally. Even their running, like every other element of this cunningly crafted tale, proves important in the end. Three “useful maps” and a couple of handy timetables, along with pointed questions and liberal hints, will help young readers solve the mystery by the final page. Happily, order is restored, and the Gaskitt family welcomes a new member. Humorous illustrations throughout expand the clever plot, and an innovative, ever-changing design will keep detectives glued to the page. (Ages 7–9, younger for reading aloud)
