A startling discovery is made after forensics accountant Ed Castillo accepts a project to inventory and value the bequeathed assets of a large estate, a requirement of the decedent's last will and testament. This inheritance represents one of the largest private fortunes in the country; it is comprised of an estimated monetary value of nearly a billion dollars. The vast fortune belongs to one of the most prominent, oldest, and most venerable Florida families; for over seven centuries, this legacy has been the birthright of all eligible descendants who can trace their lineage to the aristocratic and affluent Castaneda dynasty."
