Thanks Mark, yes, I know about Man Friday of course but couldn't see how he fitted. I was once stuck in the middle of Portugal for three days and this was the only book in English I could find. It's the sort of book you always promise to read but never do but I promised I would never go near it again. It's all full of pious motives and religious bigotry and Friday's death was treated as no great loss as he was a savage and a heathen after he had saved Crusoe on many occasions.
