Jack Gets a Clue #4: The Case of the Loose-Toothed Shark

Another funny mystery from bestselling author Nancy Krulik! When a giant shark tooth fossil went missing during my little sister Mia's birthday party at the aquarium, I found myself in really deep water -- the aquarium staff accused me of stealing it! No way would I steal something, even if it was a cool fossil. What I could do, though, was talk to the animals at the aquarium to find out who the real thief was. My brainiac detective partner Elizabeth and I would have to work fast to clear my name before the end of the day!
