Alvin’s Secret Code

When Alvin and Shoie find a secret message, they first try to break the code themselves. Then, they visit a man who knows more about codes and ciphers than anyone in town: Mr. Link, a former spy. He teaches them--and readers--how to be ace decoders. Soon they're using their skill to solve a dangerous mystery!
