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 . . .
