I sent Mia a voice message. Hi, sweetheart. Call me when you hear this. I love you. No reply arrived.

At six, Andrew and I finished dinner near the hotel. I called once more. Nothing.

“Maybe they’re in the pool,” Andrew said.

“They don’t have a pool.”

“The neighbors do.”

I tried my father again. Voicemail. Then a social-media notification appeared on my phone. Marissa had uploaded photographs.
