3x5 - Relic Hunter

Event: THE SPANISH MAIN 1790 A.D. The wife of a deceased criminal relic hunter, Jamie Palmerston, approaches Sydney and asks for her help recovering the real-life treasure that Robert Louis Stevenson wrote about in ""Treasure Island."" Nigel meets them in the Caribbean, and they follow a circuitous series of clues that Stevenson left. Meanwhile, a local dive shop owner and his henchmen are on the trail, but both of them are mysteriously shot. Sydney and Nigel find the treasure, only to find that Jamie is in league with her not-so-dead husband to get the treasure. They leave Syd and Nigel buried in the sand and then Jamie shoots her husband and takes the treasure. Thanks to a fan of Nigel's, they manage to escape and Syd punches out Jamie and gets the treasure.
