In this New York Times–bestselling thriller, the son of a WWII spy delves into an explosive decades-old secret amid tensions between England and Ireland . . .
1940: McBride, an Anglo-Irish spy, discovers a secret nest of Nazi submarines in Guernsey. As a minefield on the Irish coast is breached and German agents flow into the country-a desperate decision must be made in order to prevent the impending invasion in Britain. The consequences are deadly-and the story is kept top secret for decades . . .
1980: McBride's American son, an author, starts to dig into the history and mystery surrounding "the Emerald decision"-not realizing his own personal connection to it. And even after all these years, certain parties are willing to kill to keep the story a secret-or to exploit it . . .
