Martin was panic-stricken. David had rung to say that Emily and Petros were missing and he was scared that something had happened to them.
'They took the Asterios,' said David, 'and I think they are on the island.'
'Which island?'
'The little island in the bay. We've been exploring it. It's a long story, Dad. But they haven't come back yet and we're all scared. There's a storm about to break out. I hope they aren't out at sea.'
'Look, call the police,' said Martin, 'get them out looking for them. I shall be along as soon as I can drive over.'
