Night Probe!

Dirk Pitt proved invincible in Raise the Titanic! Now, with the future of virtually every person in the world at stake, he is enlisted to spearhead his most daring mission yet -- the rescue of a vital document for the United States. To an energy-starved, economically devastated America, possession of this document is worth billions. But to Great Britain, it's worth a war. Pitt's quest plunges him into a head-to-head confrontation with Britian's most cunning secret agent -- and into the throes of a torrid love triangle. As time runs out for a desperate America, Dirk Pitt races toward an underwater clash more terrifying than anything Clive Cussler has ever created -- the breathtaking climax of Night Probe!
