The call that changed Benjamin Harris's life forever came in the middle of the night, informing him that his grandfather, who disappeared twenty-two years before, was dead. As he adored his grandfather while he was growing up, he was determined to find out more information, in hopes that he could finally understand why he suddenly and, without notice, vanished from his life.

Ben's search for answers leads him across the country to an island near Seattle but was totally unaware that he was being drawn into a much-larger search to solve a mystery that has been ongoing for seventy-five years.

As the Second World War was coming to an end, the Nazis attempted to reposition millions of dollars in diamonds stolen from Jewish merchants throughout Europe to their agents in Argentina. The box carrying the stones disappeared en route and have been missing ever since. Many people have been hunting for the hidden diamonds, claiming that they have a right to the stolen treasure for themselves while others have been hunting to find them and return the diamonds to the victims of the crimes.

An agent of the Israeli government meets Ben, and together, as allies, find answers to both mysteries in a suspense-filled, dangerous journey leading them across international borders, in their desire to do the right thing.
