But we promised not to go out to sea at all , said Susan unhappily. She could see Titty and Roger looking at her and she turned her head away. We didn't want to do it , said John. But we're at sea now , and we can't get back in the fog. We've got to go on.
Beu........eueueueu... came the sound of the Cork lightship. It's very near , said Titty. We can't keep a promise that's already broken. Let's do what John says. Daddy would say the same. But how shall we ever get back? said Susan. When the fog clears , we'll be able to turn round , we'll be able to see things , and come back.
Beu........eueueueu...eueu..
The Cork lightship was now very near indeed , and John knew that there was no time to waste.
