In this cinematic, suspenseful World War II mystery, Caitrin Colline, the sharp-witted Welsh spy who has become one of Winston Churchill’s most trusted agents, is dropped into France to retrieve vital Nazi documents . . .

London, 1942: The threat of German invasion has abated, and the war has entered a new chapter, famously summed up by Winston Churchill as “the end of the beginning.” While Churchill faces mounting pressure and calls for his resignation, a dark new horror is unfolding across the channel, as the Nazis move forward with their plan to murder Europe’s Jews.

In the Berlin suburb of Wannsee, young SS officer Dieter Silber helps organize the conference where Reinhard Heydrich outlines his “Final Solution.” Horrified, Dieter steals a copy of Heydrich’s proposal and flees to Paris. Soon there are posters all over the city seeking his whereabouts. If he is not found swiftly, many innocents will die in his place.

Caitrin has her mission directly from Churchill himself: bring Dieter and the document back to London. Posing as a maid for another female spy, she takes up residence at the mansion opposite SS headquarters on Paris’s Avenue Foch. Once Dieter is located, the chase will begin in earnest.

Among Caitrin’s allies are a local gangster, and her aristocratic friend, Lord Hector Neville-Percy. The Resistance is formidable and courageous. But always, the SS are in close pursuit. And as Caitrin has learned, this is a war in which every moment and even the smallest decision can mean the difference between life and death.
