Treasure. Ben Hood Thrillers, #9

Put this mix together... An ancient schooner laden with stolen gold and opium, wrecked against a treacherous part of the Australian coast. A wreck diver vanishes while searching for the undersea treasure. Corrupt government officials and police crawling over each other to get their hands on the treasure. Hired killers prepared to murder anyone who gets in the way of them finding the treasure. Ex detective Ben Hood is sent to protect the stunning daughter of the missing diver and the diver's wife.
The lure of treasure often brings out the worst in normally good people. It unleashes suffering and death by the hands of normally evil people. Ben is once again pushed to the limits of his fighting skills together with personal and emotional endurance.
