England, June 1944.Exactly one week after the D-Day landings came the vengeance weapons. It was the beginning of a period which, to the war-weary inhabitants of southern England, was psychologically much worse than the days of the Blitz. With Allied forces gaining a foothold after the Normandy landings, Hitler unleashes his most vicious weapon of war yet---the V-1 flying bomb. One of these new weapons lands on a Camberwell convent, killing three nuns. Suzie Mountford and her boss and secret lover Tommy Livermore are sent to investigate. When it’s discovered that one of the dead nuns is not what she seems, they find themselves in the middle of a complex, sinister plot. John Gardner spins a story spanning feuding families, the terror of Hitler’s new warfare, and a final Nazi plot to end the war in their favor.
