Encyclopedia Brown and the Case of the Jumping Frogs (Encyclopedia Brown Series #23) by Donald J. Sobol
Can the secret weapon in Idaville’s war on crime really be a ten-year-old boy in sneakers? It can if it’s Encyclopedia Brown!
Encyclopedia is back with ten all-new mysteries to solve, along with the help of his partner, Sally Kimball, the prettiest and toughest girl in the fifth grade. They’ll have to face Bugs Meany, who’s up to his old tricks, and Wilford Wiggins, who’s still dreaming up new schemes to trick the kids of Idaville out of their money. Plus there’s lots of new characters too!
The solutions to all the mysteries are in the back—but can you solve them first?
