When they got to the coast, they went as far south (without leaving South Carolina) as they could. The 'most south town' was so small, it wasn't even on the map. But it did have a library, and a restaurant. They decided to eat first, then go to the library. They ate quickly, and 15 min. later they were at the library.
"Excuse me, miss." Lucy said to the librarian.
"Yes?"
"My name is Lucy Ricardo. Was there someone here earlier today, or any other day, who had a note for me?"
"I'm sorry ma'am. There's been nobody here with a note."
"Oh. Well - okay! Thank you."
Lucy and Ricky couldn't figure out what to do now. Were there no more clues? Had they gotten the wrong idea's? They hoped not. They sat down at a table in the library, and tried to think this out. They were both silent for a while, when Ricky said - with a thoughtful look on his face - "Let me see the last note Lucy."
Lucy pulled it out of her purse, and gavi it to him. "Look Lucy, maybe this means something." Lucy looked as Ricky pointed to the way the mystery person signed a name - 'A' name - 'A' name - "A" said Ricky. "Maybe they mean A something."
"'A' what Ricky?"
"I don't know? But I'm sure it's in a library. Lucy, bring me the first A book listed here."
Lucy went to find it, and when she came back, Ricky took it, and started thumbing through it.
"Nothing."
"Hey Ricky, maybe - I have an idea - hold on." With that she was off.
When she came back, she had a book that was something about xylophones. "What is this for?" asked Ricky.
"Just look through it."
Ricky started looking through it, and when he turned one page, a note fell out of another.
"How did you know, Lucy?"
"It was the first 'A' Ricky."
"First 'A' what? This is X?
"It's the author, Ricky."
"Lucy, you're great!"
"Oh, I know."
Ricky gave her a funny look, "Will you just read the note?"
Lucy took it, and read it. It said:

--Yahoo Lucy,
--Or Should I Say - Detective Lucy! Did You Check
--Under The Bed Before You Left Home?
--Right In The Middle? Should Be A Habit!
Your Friend Always,
Me
Who Is Me?
"Oh no, Ricky. They're back at home!"
"Come on Lucy."
"We're going home?"
"That's right. Whoever this is, they sure are leading us on a Wild Chicken Chase."
"Chicken?"
"Yeah!"
"Don't you mean Wild 'Goose' Chase?"
"Whatever. Come on."
"Okay."
