The first of three episodes that veers between Mason's time on the island working with the frustrated, and possibly mad Maskelyne, and his recounting of events to Dixon upon their joint return to England. Mason and Maskelyne, whose obsession with his faulty instruments only grows, visit the haunting Windward side of the island for observations. Maskelyne tells Mason how a soldier he saved from throwing himself off a nearby cliff now harbors hope that Maskelyne's connections to Clive will get him out of further service on the god forsaken island. Amidst unceasing wind, Mason suspects the soldier is in fact a ghost, and the ghost of Mason's late wife Rebekah visits him for the first time.
