1. On the Beach

Curly and Boysie have been for a stroll along the beach. They decide to have a rest on the sand before they head for home.

"I love the beach," says Curly. "It is such a restful place."

"So restful that I think I'll have a little sleep," replies Boysie.

The friends close their eyes and start to drift off to sleep. Suddenly, Curly sits up. "What was that!" she shouts.

"What was what?" asks Boysie in a sleepy voice.

"I thought I heard someone calling," says Curly.

"I expect it was me, talking in my sleep."

"Do you often talk in your sleep, Boysie?" asks Curly.

"I don't know. I never wake up in time to hear myself."

"Perhaps it was you, then," says Curly as she lies down again.

No sooner has she closed her eyes than she hears the voice again. "Hey! You!"

"Boysie, I did hear something," says Curly.

Boysie sighs. "I expect you were dreaming. Go back to sleep."

"I can't," says Curly. "I must find out who that voice belongs to."
