I drag Vi and Zach to the car and get in. "Lock the doors," I say to Zach from the backseat.

"What?"

"I said to lock the doors!" I whisper.

"Katie, what's wrong?" Vi asks. I hear the doors click.

"Drive, and I'll tell you." Zach starts the car. "That's the killer. O'Hilda killed my parents."

"Are you sure?" Zach asks.

"I'm sure. She had motive, and the toy store and Ms. Atkins is in on it too!"

"You think she left the notes?"

"I thought the killer left the notes. But now I'm not so sure."

"Why not?"

"Well, we got threats too. The killer wouldn't write clues and threats. That's like a teacher posting up the answer key but not letting us look at it. She wouldn't encourage us to find her, but then threaten us when we're close."

"Okay, so?"

"O'Hilda left the threats."

"Okay, and?"

"Ms. Atkins is in on it too. But how?" Zach phone beeps.

"You signed up for the newsletter?" Vi asks.

"Yeah." He pulls into my driveway and looks at the email. "Oh, god. If you're right. This is bad. This is really, really, bad. This is horrid."

"What?" I say.

"Update, along with meeting Dolly, our meet and greet will now include three special guests. Ruby Atkins, founder of Boho Fro-Yo, and Ronda and Carl O'Hilda, founders of O'Hilda Toy Barn."

"What?"

"We can't go to the meet and greet. It will be way too suspicious!"

"But, Vi, can. Instead of Zach and I, you and your sister can go. Zach and I will still be outside the store."

"What? I'm not, I don't know anything!"

"Yes, you do. And it won't be any risk to you nor your sister. Just go in, we'll be on the phone, confirm that it's Leo, and we'll call the police. Simple."

"Please, Vi, for me?" Zach asks.

"Fine, but I'm keeping one of these dolls. You did say it was for my sister."

"Deal."
