Dead in the Water is the 127th book in the The Hardy Boys Casefiles series. It was published in in late 1997/early 1998 by Arcway Paperbacks (an imprint of Simon & Schuster). Although, further volumes were planned and even written, this the 127th volume, turned out to be the last Casefiles ever published.
During the early years of World War II, the legendary and lethal Nazi U-boats spread terror from beneath the sea. Now, more than fifty years later, on a salvage operation off the coast of Florida, the Hardys plunge into the rusting hull of one of those awesome submarines...and discover that the terror still lives!
When Alvin Mann, leader of the salvage operation, vanishes without a trace, Frank and Joe vow to rescue him -- and find out what deadly secret lies hidden on the ocean bottom. But first they'll have to confront a brutal adversary armed with knives, spearguns, and more -- an enemy determined to blow them out of the water!
