NOTICE
I have kept the events in this story, to the best of my power, strictly within the bounds of scientific possibility, the bounds of what has happened or can happen. Nevertheless it is intended to be a work of fiction, not of history: and no single character in it is intended to be a portrait of any living person. R. H.
