Sinking Island

At the base of a cliff on Sagorah Island, 82 year-old American billionaire Walter Jones is found dead next to his life's work; a massive Art Deco tower he had dreamed would become an elite getaway for international jet-setters. The only clues found at the scene include his wheelchair, abandoned at the edge of the cliff, and multiple scratches on his face. One of these scratches appears to have been made by a woman. Ten people were present on the island at the time of his death, among them the heirs to his vast fortune and legacy. Was his death an accident or murder?
