Dirk Pitt finds uncut diamonds on a shipwreck in the English Channel during a diving expedition. The discovery links to a wartime mystery from May 1940, when the chief curator of the Musée de l'Armée fled Paris with secret cargo as German forces invaded. The curator's mysterious object ended up on a decrepit steamer that sailed under enemy fire after his original ship was destroyed at Le Havre. When thieves steal the diamonds Pitt recovered, he uncovers something far worse than robbery. A murderous organization plans to attack water treatment plants worldwide, threatening billions of lives. Pitt and his NUMA team race from Paris to the Irish Sea to the Caribbean islands. Working alongside his children Summer and Dirk Jr., Pitt must locate the wartime treasure that holds the key to stopping global catastrophe and preserving a nation's heritage.
