In the final episode of the series we search for the Cascades, the mysterious Whirlpool of the Dead, and the furthest place that Arthur reached on his expedition. We are able to put some ghosts to rest, and turn for home. But there are a few more surprises in store on the way back as we stop at Pampa Whaley, the last outpost of the Peruvian Corporation, now run by a co-operative and still producing coffee.  In Lima we say goodbye to Peru, and Arthur, and leave this new story for future travellers to find.
