A lethal legacy

Finn Douglas plans to use his inheritance to turn a rambling manor house on New York's Douglas Island into a resort. But when his business partner's broken body is found at a cliff base Finn fears it wasn't an accident--and asks his cousin Special Agent Craig Frasier to investigate. Craig and psychologist Kieran Finnegan delve into the history of the Douglas estate discovering the strange lore and blood-soaked past of the island and its caverns. In Kieran and Craig's search for the truth one false step could send them plummeting to their own deaths and one wrong turn could bring them face-to-face with a killer.
