Interweaving three narratives, a story of love, mystery, and murder during World War II follows three courageous women--an award-winning British landscape designer, a young, blind perfumer's apprentice, and a junior British intelligence officer.

Near the end of World War II, Marthe, a young blind woman apprenticed at a perfume factory in Nazi-occupied Provence, finds herself at the center of a Resistance cell. Iris, a junior British intelligence officer in wartime London, falls for a French agent. Years later, on the lush Mediterranean island of Porquerolles off the French coast, Ellie has been hired to restore a memorial garden. She is unsettled by the bitterness of the garden's owner, an elderly woman who seems intent on undermining her. A vivid chronicle of love and loss in the fog of war.
