The Cryptic Case of the Coded Fair

by Barbara Tinker, Robert Tinker, Pendred Noyce
Dr. G and his companions are using coded messages in a plot to corrupt the International Science Fair. Quarkum Phonon, a Dude from the future, calls on four middle school students for help. Benson and Anita work on their computers while two new G.A.S. recruits, Ella and Shomari, travel through time, facing kidnappers, thieves, and spies in their scramble to learn about codes and ciphers. Across two millennia and five countries, they meet Julius Caesar, Thomas Jefferson, Alan Turing, and others, while learning about substitution ciphers, frequency analysis, wheels, cylinders, book codes, the Verginère Table, the Enigma, and public and private keys. But will they break Dr. G’s code in time to save the science fair?
