Chapter Thirteen

“Mrs. Robinson! Mrs. Robinson!” I ran up to the librarian. “I know where your key is!”

“Where is it?” asked my mom.

“You found my key?”

“Great job, Lark!” said Halmoni.

“May I please see your book?”

Mrs. Robinson handed it to me.

I opened it. And there, placed in between the last two pages she’d read, was the key. “When you saw Sophie, you were worried and scared for her. And you weren’t thinking of your key. You stuck it in your book so your hand would be free in case they needed you!” I stopped and thought. “And maybe so you didn’t lose your place in the book too. That can be kind of annoying when it happens.”

“Lark! You’re amazing! Thank you!” Mrs. Robinson gave me a big hug.

And I hugged Connor. “Thanks for your help.”

He didn’t look happy. “I don’t think I was really helpful. I’m sorry I left you.”

“No, it was good you did. I got to be alone to think.”

“Really?”

“Really, really.”

He smiled. “Maybe I should leave you alone more often.”

“I wish!”

Mrs. Robinson opened the library and everyone went inside.

Except me.

I still had one job to do before the case was over.
