"Sometime during the early hours of the morning, he awoke again, this time with a start. He was sure he heard a noise outside. It sounded like a twig snapping. Under normal circumstances it would have meant nothing, but in the silence of the forest every sound was magnified. There it was again. This time it was closer and his instinct told him it wasn't the wolves. He reached for his gun and quietly looked out through the window. The moon was on the wane, wrapped in the soft gauze of snowfall and it wasn't easy to see. Maybe it was a fox, or even a deer. Then he heard it again, right outside the door. He cocked his gun, pressed his body flat against the wall next to the door, and waited. The room was in total darkness and his senses were heightened. After a few minutes, he heard the soft click of the door latch." February 1944. Preparations for the D-Day invasion are well advanced. When contact with Belvedere, one of the Resistance networks in the Jura region of Eastern France, is lost, Elizabeth Maxwell, is sent back to the region to find the head of the network, her husband Guy Maxwell. It soon becomes clear that the network has been betrayed. An RAF airdrop of supplies was ambushed by the Gestapo, and many members of the Resistance have been killed. Surrounded on all sides by the brutal Gestapo and the French Milice, and under constant danger of betrayal, Elizabeth must unmask the traitor in their midst, find her husband, and help him to rebuild Belvedere in time for SOE operations in support of D-Day.
