The Deep (Imprint # 28)

When a couple go on a scuba diving excursion off the Bermuda coast, they find a variety of treasures, including a container of mysterious liquid and an antique medallion with a woman's likeness on it. Eventually, a drug lord takes notice and begins to terrorise them with Haitian black magic when they refuse to sell the liquid to them. The couple begins to research the history of the Spanish shipwreck and realise how valuable the ship's contents actually are and conflict ensues as the treasure hunters battle the drug dealer and his henchman.
