Dreadnought's Curse — Howard Hoyt Hilton

Early in WWII, the German pocket battleship GRAF SPEE was scuttled under mysterious circumstances. Today, its ravaged hulk lies deep in the waters of Rio de la Plata near Montevideo, Uruguay. As a result of a bizarre series of events, Charles Garner, grandson of one of the GRAF SPEE's officers, discovers startling information which leads him to believe the ill-fated dreadnought had been carrying something of immense value ... something which he is convinced is still aboard the sunken wreck. Arriving in Montevideo and diving on the ship with Dave Walker, a professional diver, they make a grisly discovery while retrieving a treasure worth a fortune. Unknown to them, others seeking the prize have been shadowing their every move. A series of murders leads up to the climax when all contenders for the prize meet aboard a luxurious cruise ship. A violent showdown culminates in a surprising, shocking ending.
