A new adventure with underwater investigator and treasure hunter Chris Green. A chance encounter with an old friend in Fort Lauderdale and an invitation to visit a new island operation where her friend is the head director seem innocent enough. Chris decides to go for a visit and is impressed with what she sees. A fatal accident is unfortunate in the idyllic setting, but there's no reason to be suspicious. A telephone call to Chris raises the first doubt, leading to layers of secrets no one expects.
