Book 1 in the Gage Finley series of underwater action adventures.
While hired to life a submerged airplane for the U.S. government, Gage Finley discovers beneath it a flintlock pistol, one of two linked to the captain of the Scavenger. That was a pirate ship sunk in the Bahamas in 1717 and said to have chests of gold worth millions. Gage and his friend Duke and his daughter Niki go after the treasure but must deal with deception all around them.
