Following a highly successful and exceptionally lucrative salvage operation on an American freighter by the South West Deep Ocean Salvage Company, sole owners Kevin and Karen Masters after so many lean years became rich beyond their wildest dreams. But with wealth came boredom, so just to pass the time they mounted a hunt for HM Submarine Troy documented by the Admiralty as lost with all hands on her return passage from Operation Trojan Submarine in Dorfhaven Germany during WW2. Within weeks their search was intercepted and they were dragged, somewhat reluctantly into a larger Government sponsored hunt led by one Charles Littlewood. Hours of research frequently resulted in far more questions than answers frustratingly hindered by the constant threats of abduction, attempted murder, sabotage, cyber-attacks and piracy before finally discovering the whole shocking truth of this valiant craft.
