Crusoe, old and rich and unable to sit still, goes back to his island — then on to Madagascar, India, China and overland across Siberia to Archangel. Defoe published the first book at fifty-nine and this sequel four months later; it sold, it was read for a century as the other half of the story, and it is where the castaway turns into something much less comfortable: a trader, a passenger, an old man who cannot stop moving.
