 THE CLASSIC DIRK PITT ADVENTURE A NUCLEAR PEARL HARBOUR
Buried in the depths of the Pacific Ocean, off the coast of Japan, lies one of the greatest drowned secrets of World Wart Two -- a crashed B--29 Bomber that was carrying a third atomic bomb to Japan in 1945.

Its deadly cargo, lost in the sea for nearly fifty years, is at the heart of this classic Dirk Pitt thriller, in which a small group of Japanese nationalist fanatics, dreaming of a new Nipponese Empire, set out to neutralise and blackmail the USA -- with nuclear weapons planted strategically in the country's major cities!
