A family's innocent search for answers brings a long-forgotten, twenty-five-year-old mystery to light, in the riveting new novel from the bestselling author of The Things We Cannot Say.

1970--In the aftermath of his war-ravaged past, Noah Ainsworth is still haunted by memories of his time as a fearless British operative in France. But a critical head injury left Noah with frustrating memory gaps and a burning question that plagues him--who was the agent who saved his life during that tragic final mission?

Determined to find answers, Noah's daughter Charlotte embarks on a quest from their cozy home in Liverpool, leading her to the incredible lives of two ordinary women--Chloe and Fleur--who transformed into fearless spies on foreign soil. But as Charlotte unravels the heroic exploits of these women and their connection to Noah, she inadvertently stumbles upon evidence of a double agent lurking disturbingly close to home, drawing her into a treacherous web of secrets and unearthing a shocking story from those final days of the war.

Once again, Kelly Rimmer takes readers on a gripping journey, one that threads the lives of two remarkable women into the fabric of history, unveiling the power of courage, family and the indelible mark left by the darkest era of human conflict.
