A Start (part 7)

The last time we saw Andy was at lunch when he and his friends were decoding the note.

The group sat in silence. They didn't know where to start looking.
"I know!" exclaimed Andy.
"What?!" asked Jordan and Jake at the same time.
"We can look at the way the letter was written!" explained Andy.
"Well," said Jordan, " The person has to know a lot of history to recreate the world's biggest problems."
"So the person should have access to a lot of books. " said Jake.
"Exactly, I know exactly where to look." said Andy, "Meet me at the library after school."

After School...

"How do you know that the person who wrote the note comes to this library? There are so many libraries in just the town! Not to mention the whole city!" exclaimed Jordan.
"I have to agree with her on this now, Andy." explained Jake.
"Well, this library has the most information about history, plus how can they be watching me and knowing me if they live far away? Anyways, this is where all universities get their history books. It must be the place!" Andy explained.
All of them walked into the library.
"Let's ask the librarian. This librarian takes note of people who come here daily." whispered Andy.
"Hello? Are you a librarian?" asked Jordan in a too-of-a-sweet-tone.
"Why, yes I am. How may I help you?" the librarian asked.
Her name is Judy.
"Hi! I'm Jordan, this is Jake, and this is Andy. We are here to ask you some questions, if that's okay..." asked Jordan.
"Of course that's alright!", said Judy with a smile, "Fire away!"
" Alright, how long have you been working here?" asked Jordan.
"I've been working here ever since it opened. Ever since then, I have been noticing people who come here daily. Most of them, wonderful people, but some of them aren't as kind." said Judy in a sad tone.
"Do you know their names?" questioned Andy.
"Well, there is only one. His name Chris. That is all I know! He doesn't come with any friends and seems mysterious and just blends in. He checks-out some weirds books that people on glance at. He looks at the books in the reference section. Really weird, huh?" asked Judy.
"Yeah, it is. Well, thanks for answering our questions! See you later!" said Jordan.

" Well, at least we got some where." said Jordan.
"Yeah, but we just got stuck with another question, who is Chris?" said Jake.
