Lady Emmeline "Foxy" Butterschloss lives in self-imposed isolation on her country estate. She is haunted by her experiences six years earlier as an ambulance driver on the Western Front and the loss of her husband during the war. After her war work in France, she spent the rest of the war as a gifted cryptologist for the Royal Navy. However, the veil of secrecy drawn over her work and that of other women in naval intelligence makes her feel useless and discarded in the war's aftermath. She is pulled back to the world of intelligence when the top-secret records of the sinking of the Lusitania suddenly disappear, and someone tries to kill her adult adopted son, who was the last person to see the files. Foxy rediscovers her indomitable-if often impetuous-will and deploys her considerable skills as a sharpshooter and a cryptologist to rescue Dinny and his friends from the dangerous world of political intrigue and espionage. Winston Churchill was First Lord of the Admiralty in 1915, when a German submarine torpedo sank the Lusitania . Powerful people do not want the damning secrets in the Lusitania files to emerge on the eve of Churchill's run for Parliament in 1924. Foxy also solves the murder of a whistleblower who was about to expose a plot by MI5 and Conservative party leaders to smear the Labour Prime Minister as a stooge for the Soviet Union. As she investigates both mysteries, Foxy realizes sinister forces are at work and her life is in danger. Can the man who has secretly loved her for decades protect her? And can she learn to love again before it is too late?
