Madame Fiocca by Suzy Henderson

February 1933: Nancy Wake is a gregarious twenty-year-old looking for adventure. Having fled her unhappy family home in Sydney, she becomes a journalist and is thrilled when she is posted to Paris. The city is glamorous, brimming with journalists, artists, and a growing number of refugees.
Later, in the French Riviera, she uncovers more than news following a chance encounter with wealthy industrialist, Henri Fiocca. Their relationship blossoms as Hitler makes waves across Europe. While on an assignment in Vienna in 1938, she witnesses Nazis whipping Jews on the street and she vows to fight for justice if ever the opportunity arises.
When Henri is called to the Front to fight, Nancy, determined to help the war effort, joins the Red Cross as an ambulance driver. Every day she witnesses atrocities. When Paris falls, Nancy flees the German oppressors and returns to Marseille. France is a nation defeated; its people are in despair.
A chance encounter with a British officer draws Nancy into the heart of the Garrow escape network, despite Henri’s reservations. Armed with wealth and charm, she convinces Henri that the Germans will never suspect such a woman. But soon she finds herself caught up in a deadly game of espionage.
As the iron fist of the enemy tightens, neighbours denounce neighbours. No one can be trusted. When the enemy closes in, Nancy and Henri face an impossible choice. Has she done more harm than good?
Based on a true story of love and a gripping adventure, Madame Fiocca weaves an extraordinary tale of survival and redemption in wartime.
