The New York Times bestseller—for fans of All the Light We Cannot See and The Tattooist of Auschwitz!

Three women. One daring mission.

Manhattan, 1946. One morning while passing through Grand Central Terminal, Grace Healey finds an abandoned suitcase tucked beneath a bench. Inside is a dozen photographs—each of a different woman. Grace soon learns that the suitcase belonged to Eleanor Trigg, leader of a network of female secret agents deployed out of London during the war. Twelve of these women were sent to Occupied Europe as couriers and radio operators to aid the resistance, but they never returned home.

Setting out to learn the truth behind the women in the photographs, Grace finds herself drawn to a young mother turned agent named Marie, whose mission overseas reveals a remarkable story of friendship, valor and betrayal.

In this riveting story inspired by true events, Pam Jenoff weaves a tale of courage, sisterhood and the great strength of women to survive in the hardest of circumstances.
