[Ellie's P.O.V.]
"The books on the bottom row are thicker than the ones on top, and there are fewer of them. There are only nine books." Kirk even went to count the books as he told me what he found.
I took a look and it was really so. That was why the books were so neat and fully occupied the entire row of bookshelves. Every book had a different number on it. I connected them from one to nine. It wasn't too strange and there was no pattern to it. I was discouraged again. The feeling of finding clues but not knowing where to start was too uncomfortable.
"Sister Ellie, don't be discouraged. We've made a new discovery, haven't we? Maybe there's a secret code hidden in these nine numbers!" Kirk consoled me.
A password? I flipped the book in my hand over and over again, staring at the number and falling into deep thought.
