“Morning,” Dad said. “I hope you slept well?”

I nodded but avoided the question. “Have you seen Rosie?”

“She’s outside with Charlie,” Kate told me.

“What? Charlie’s in bed asleep. I just saw him.”

“Oh. He must have gone back to bed then. He was out there earlier.”

I could see Rosie through the window, so I let myself out and made my way along the cliff path towards her. She was examining the screen of her camera, but looked up and waved when she saw me.

“You’re up early,” I said.

“I couldn’t sleep,” she replied.

“The blow-up mattress isn’t very comfortable, is it?” I said.

“No, it wasn’t that.” She fiddled with her camera strap. “I had a horrible nightmare. About eels. And birds. They were trapped inside the lighthouse, looking for a way out. It’s made me feel a bit unsettled since I got up actually. You know those dreams that just make you feel a bit … weird? Like you’re not yourself?”

I noticed that she looked pale and had to resist 101the urge to reach out and put my hand against her forehead.

“At least you’ve got nice weather for photography today,” I said, gesturing at the sun sparkling off the blue waves.

But Rosie pulled a face. “Not much good for spooky photography,” she pointed out. “I would’ve preferred dark skies and ominous clouds. Perhaps it will turn overcast a bit later.”

She took out her phone to check the weather.

“No signal, remember?” I reminded her.

“Oh yeah.” She shook her head. “Habit.” Then she frowned at her phone and said, “That’s weird.”

“What? Have you got a signal?”

“No, it’s not that. My lock screen is a photo of the lighthouse.”

“So?”

“So I didn’t set it.”

I shrugged. “You must have pressed something by mistake.”

“I guess.”

She went into her phone, but then her eyes narrowed. “This doesn’t make sense,” she said. “It’s the photo of the lighthouse I took when we arrived 102yesterday – the one I deleted because it was all blurry, but now it’s back in my library and it’s set as my wallpaper too. Look.”

She passed me the phone, and I saw that she was right. There the blurred photo was, time-stamped from yesterday.

“Maybe it’s a glitch with your phone, or you pressed the wrong button,” I said, handing it back with a shrug. My stomach gave a growl and I thought of the toast in the kitchen. “I’m starving. Why don’t we go and have breakfast?”

“OK.”

Rosie deleted the lighthouse photo, then we went back inside where Kate and Dad were clearing away their plates.

“Hi, girls,” Kate said cheerfully. “There’s toast and cereal on the side.”

“Thanks,” I said.

I grabbed a piece of toast for me and one for Rosie.
