Tonya listens to the sea. She likes the noise. Then she hears something different.

‘Is it a baby crying?’ she thinks and looks up.

Ten metres in front of her is a big fin . . . a very big fin. Under the fin is a killer whale. The whale is making the noise. But it is not a baby – it is five metres long. Behind it is another whale. And another. And another.

‘Killer whales eat people. I am going to die,’ thinks Tonya.

The killer whales come nearer and nearer. Tonya can’t feel her legs.‘It’s OK, they are cold. That’s all,’ she thinks. She starts to swim away from the big fins.

‘Help me!’ she shouts. ‘Help, help, help!’

The killer whales are all around her. She closes her eyes and waits.
