A series of strange events in and around a group of volcanic islands in the Augean with associated happenings in London. On a bright morning,  Ian Caudray, a young devotee of archaeology and of the classics swims from a yacht to one of the islands which he believes is uninhabited.  When a beautiful girl appears he thinks of her as Nausicaa with himself as Odysseus- but she makes it clear she doesn’t share his fantasy and wants him gone! Discouraged, he returns to the yacht for breakfast and a light-hearted inquisition from his family – but it’s not long before the beautiful lady’s secrets come out.
