Troubled Waters

Brian Stead visits Tembigo to inspect Mogul's costly new semi-submersible rig, the Moaia, and tells Peter Thornton he is to be transferred back to London. Meteorologist Denny Carson is tracking Hurricane Sophia, which looks likely to miss the island, though some of the crew feel uneasy about the rig. When the storm changes course, Thornton finds himself aboard the Moaia as it bears the full force.
