|'Sea of Oil'
by Dennis Spooner
When the crew of Stingray are sent to investigate the mysterious destruction of an oilrig, Atlanta is captured by members of an undersea race. She soon learns that her captors merely attacked the rig out of self-defence, as they believed that it was about to attack their home; however, the realisation comes to late: a bomb has been placed aboard Stingray - and when the vessel next dives, the deadly device will blow Troy and Phones to pieces...
