Mr. Weaver spread the yellowed map of Beantown on his workbench.

"Kids," he said excitedly, "this map is over 100 years old, and it's written in code!"

"Wow, what could it mean?" said Willie as he peered over his dad's shoulder at the confusing jumble of faded letters. "How can we decipher this?"

"I know how!" announced Grace. "My brother Miguel is home for Thanksgiving. He is in the Navy, and his job is working with codes. Let's take this map to him."
