Drama Sailing in the Menacing Caribbean

They were five at the beginning, all family members looking for an adventures tour, sailing in the Caribbean, leaving a foggy London and a frostbitten Norway behind them. One of them wasn't supposed to be there at all, but had to step in as skipper for his son now being busy with his broken arm. The sex bombe was totally keen on this trip, while her snobbish husband was there on a mission, sailing was just an excuse for ulterior business. And it didn't take long until they were only 4, and then three. But who was to go first? Sharks, and murders, sex and more to follow on this 18 days trip from Sint Martens to Grenada
