The Golden Keel

The Golden Keel by Desmond Bagley

Mussolini's missing treasure - worth three million pounds - lies hidden in Italy. A group of adventurers set sail to track down the treasure and smuggle it out, encountering many enemies along the route, including murderous ex-partisans, ruthless beauties and menacing smugglers, all of whom will stop at nothing for a chance to hijack the fortune.
