Britain's secret intelligence service, MI6, has lost contact with its informant in northern Italy, just as important information about the future plans of Austria and Nazi Germany is coming to light. And young Elena Standish, to her surprise, is the only person who can recognize MI6's man--because he is her former lover. Aiden Strother betrayed her six years before, throwing shame on her entire family. Now, with so much to prove, Elena heads to Trieste to track down Aiden and find out what happened to his handler, who has mysteriously cut off contact with Britain.
As Elena gets word of a secret group working to put Austria in the hands of Germany, her older sister, Margot, is in Berlin to watch a childhood friend get married--to a member of the Gestapo. Margot and Elena's grandfather, the former head of MI6, is none too happy about the sisters' travels at this tumultuous time, especially when a violent event at home reminds him that even Britain is growing dangerous. As his own investigation collides with his granddaughter's, what's at stake on the continent becomes increasingly frightening--and personal.
