When Larry becomes a night guard at New York's Museum of Natural History, he expects to have an easy job. But on his first night, he dozes off, then wakes up to the most amazing vanishing act in the museum's history. The museum's entire collection of dinosaur skeletons has disappeared! In a panic, Larry rushes from one room to the next- then dashes outside into Central Park, and next door into the planetarium. Where did the skeletons go? Who is the dinosaur thief? - And how in the world can Larry get those dinosaur bones back again? Originally published by Barron's in 1993, this mystery-comedy for kids returns in print as a complement to the major motion picture that it has inspired.
