What’s it about?
The story.
Blue River Creek has a problem: pets are disappearing, and Sofia and Iggy are convinced a pet thief is on the loose after their own animals go missing. But Ada Twist is a scientist, and she knows better than to jump to conclusions. Instead of panicking, she makes a hypothesis, collects data and runs experiments to find out what's really happening—before even more pets vanish. As the Questioneers set traps, gather clues and follow the evidence, Aaron Slater's funny warning posters keep the neighbourhood on alert and the team works together toward a logical answer. From the bestselling Beaty–Roberts team, this illustrated chapter book turns the scientific method into detective work, showing young readers how to slow down, question assumptions and let facts lead the way. David Roberts's lively illustrations capture the worried pet owners, the homemade trap and the whole diverse gang of friends. Warm, funny and full of real thinking, it's a reassuring mystery for animal-loving readers.
