Description:

Dirk spots smoke on the horizon from his NUMA research vessel and races to the flaming cruise ship Golden Dolphin in time to save most of the 2,000 passengers and crew, including Kelly Egan, beautiful daughter of the inventor of engines that run on seawater. Dr. Egan drowns, leaving Kelly with a leather case that she believes contains the secrets of his life's work but a couple of ruthless villains want it, too, and with Dirk's help she narrowly escapes. When the Dolphin wreck sinks, Pitt and Giordino use a mini-sub to search for arson clues, but the NUMA ship and crew are hijacked while the sub is under and Pitt and Giordino drift until rescued by a private boat. They then cross paths with Curtis Zale, a ruthless oil baron bent on monopoly and unafraid of using mass murder to gain his ends. Meanwhile, Congresswoman Loren Smith, Pitt's erstwhile lover, heads a committee probing Zale and is added to the target list.
