Anna Bauer has served Mrs. Katty Perry and her daughter Rose for twenty years in the cathedral town of Wannington. Her complete integration into the Perry household makes her an indispensable fixture of quiet suburban comfort. Domestic routine and long affection obscure any sense that her German origin might ever separate her from the English community she feeds and maintains.
The onset of World War I in August 1914 suddenly alters the context of everyday conversation in Wannington. German contacts like Herr Valantine exploit Anna's trusting nature, drawing out casual remarks about local British troop movements without her understanding their military value. What feels to Anna like simple neighborhood talk serves a calculated foreign intelligence operation right under her mistress's roof.
The discovery that her harmless confidences assisted enemy operations breaks Anna's spirit. Trapped between her deep emotional bond with Mrs. Perry and the disastrous consequences of her manipulated words, she faces the devastating truth of her position. War leaves no room for neutral affection, turning personal devotion into a weapon that destroys the innocent from within.
A devoted German servant in Wannington becomes an unwitting instrument of espionage when World War I erupts.
