Leo and the Museum Bone Heist
Ages 6–8
When a precious fossil vanishes from the dinosaur wing, eight-year-old Leo must use numbers, not guesses, to find out what really happened.
Children learn that careful observation and checking facts, rather than jumping to blame, is the best way to solve a mystery.

Saturday mornings meant one thing: Junior Detective Club at the museum! Leo raced past the giant sauropod skeleton, loupe bouncing on its cord. Nell was his best partner in the club, notebook always ready. "Today's mystery is a good one," she whispered. Behind the rope, a curation cart waited, its velvet trays lined with numbered fossils glinting under the amber lights.
"Wait," Nell said, stopping short. "Tray four is empty!" Leo turned his face up, eyes wide, looking straight at the little brass tag with a number but no bone. "The toe bone," he gasped. "The big sauropod toe bone is gone!" Gustavo, the volunteer, hurried over, hands fluttering nervously by the cart.
"I only stepped away for one moment!" Gustavo said, wringing his apron strings. "Was it stolen?" Nell frowned at her notebook. "Not yet," she said firmly. "Check the numbers first. Every fossil has an accession number, and every drawer has a matching one." Leo nodded, loupe glinting. "Numbers don't lie."
