Night probe! 1981

In the midst of an international crisis, Heidi Milligan, a beautiful, brilliant American naval commander, accidentally discovers an obscure reference to the long-buried North American Treaty, a precedent-shattering secret pact between the United States and Great Britain. The President believes that the treaty offers the single shot at salvation for an energy-starved, economically devastated nation, but the only two copies plummeted into the watery depths of the Atlantic in twin disasters long ago. The original document must be found—and the one American who can do the job is Dirk Pitt. But in London, a daring counterplot is being orchestrated to see that the treaty is never implemented. Brian Shaw, a master spy who has often worked hand in hand with American agents, now confronts his most challenging command. Pitt’s mission: Raise the North American Treaty. Shaw’s mission: Stop Pitt. 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!
