Surely he’ll see that I am not a threat.Slowly, slowly, the hand gripping the stone relaxes. Even more slowly, he lowers his arm.“Who are you?” I ask, keeping my voice soft and level, but then I remember that he probably doesn’t speak any English.

He is surrounded by flotsam and jetsam. Suddenly I realise what must have happened. There was a freak wave. It must have lifted him, hurled him over the beach and the dune, and half-buried him in the sand. He’ll be freezing cold. It’s amazing that he hasn’t died of hypothermia.“It’s all right,” I say again, “I’m a friend. I want to help you.” Then I have an idea.
