When he straightens up, he notices for the first time a curious green glow, which constantly varies in intensity. He gazes at the oscillating light and listens to the alternate boom and splash of water which is drumming about him. Then, surprised, he recognises the sound of the sea. Even as he realises this, in his waking consciousness, he is overtaken by a moment of panic. The tide. The tide is coming in.
