A dead millionaire. A fortune to be inherited. When everyone is a suspect, and everyone has a secret, will anyone ever know the truth? Money. Power. Beauty. The Wilson family had it all. But when patriarch Thomas Wilson II suddenly dies in the middle of their annual Caribbean yacht cruise, his widow and three children are left reeling. Did Thomas really have a heart attack and accidentally fall overboard like the autopsy said? Or is there a murderer on the loose?
