“I’m probably being super paranoid, but please tell Isabelle not to let her out of her sight today,” Letty whispered in Ava’s ear. “I know it’s a lot to ask, but keep her inside, away from the pool or the beach. Just in case.”

Ava patted her arm. “Don’t you worry. We’re not gonna let anything happen to that little one. Or to you. And that’s a promise.”

“First off,” Vikki Hill asked Letty, “how is it that you were able to recognize Declan Rooney? It was my understanding that you never met the man.”

They were sitting in the living area of Letty’s unit.

Letty turned to Joe. “After you told me about Rooney’s connection to Tanya, I looked up his booking photo online. But there’s something else…”

She clasped her hands in her lap. “I was going to tell you guys. First thing this morning. But then stuff was happening so fast…”

“Tell us what?” Joe asked.

“About the nanny cam. In Ellie. Tanya must have sewn it there. So she could snoop on Evan when Maya was with him. She never said a word about it to me. I only found it by accident.…”

“Whoa! Who’s Ellie?” Agent Hill looked from Letty to Joe. “A nanny cam?”

“Ellie is Maya’s stuffed elephant. Like, her security blanket. Right? But this is the first I’m hearing about a nanny cam,” Joe said. “Letty?”

“The other night, after the barbecue, Isabelle was babysitting and Maya fell asleep and we were carrying her inside to put her to bed, and she must have dropped Ellie out in the breezeway. It was the night it rained so hard. Anyway, I found her out there, Ellie, that is, not Maya, in a puddle, and I was drying her off with a hair dryer, and I felt something hard—inside, like, her forehead. So I got some scissors, and dug around, and I pulled out this thing. It turns out it was a tiny video camera. I didn’t know what to do with it, but I asked Isabelle, and she has a friend from school who’s sort of a hacker, so Sierra came over, and…”

“You told my seventeen-year-old sister about this nanny cam? But not me?” Joe interrupted.

“Yeah. I did.” Letty was unrepentant. “Turns out Isabelle had already figured out that I’m Tanya’s sister. This was before Agent Hill showed up. While I still wasn’t sure I trusted you. Can I keep going now?”

“Be my guest.”

Letty quickly filled them in on how she’d figured out her sister’s password, which allowed Sierra to access the nanny-cam videos on Tanya’s iCloud. And she gave them a description of the content that she’d watched the night before.

“We need to see that video right now,” Vikki Hill said. “Did you watch all of it?”
