Former New York City police detectives-turned-Brooklyn private investigators Karin Schaeffer and her husband Mac survived when brutal terror invaded their lives more than once. Now the offer of $30,000 for one day's work in London, followed by a family vacation in an exotic locale, seems too good to be true. And then they discover that it is.

Putting Mac's investigations into the alleged marital infidelities of billionaire Godfrey Millerhausen on hold, the family finds paradise in the sun-drenched Mediterranean island of Sardinia. But the holiday turns dark and terrible when the children vanish. Suddenly Karin and Mac must unravel a deadly web first spun when wronged wife Cathy Millerhausen walked into their world --- as they discover firsthand the true evil of big money: how far it reaches, what it buys ... who it kills.
