Society heiress Evelyn Brooke-Edwards is a skilled interrogator - her beauty making her a non-threat in the eyes of the prisoners. Farm girl Betty Connors may not be able to type as she claimed, but her crack analytical skills soon find her unearthing covert connections. German ex-pat Judith Stern never expected to find herself listening in to German POW's whispered conversations, but the Nazis took her father from her so she will do whatever it takes to help the Allies end this war. Billeted together in the attic of Latimer House - a place where secrets abound - Evelyn, Betty and Judith soon form a bond of friendship that carries them through the war. Because nothing is stronger than women united. Tucked away in the Buckinghamshire countryside, Latimer House, a grand country estate, stands proudly - a witness to some of greatest secrets of WW2.
