"Hampshire, 1943. Kim Maxwell has been languishing in the ‘cooler’ in what she sees as punishment for getting caught — and tortured — by the Nazis, before being freed by Resistance fighters and smuggled back into England. Now she is sent for by the head of SOE. This is her chance to prove herself. A fellow agent has been found murdered. It would seem that Lilian Harvey heard something she shouldn’t have and that her murder was a warning. Setting out to uncover the culprit, Kim spots a strange zigzag pattern on the wall above the bed where the body was found, which Lilian drew using her own blood as she lay dying. Before Kim knows it, she uncovers evidence that there exists a dark society working in the shadows and she realizes the Nazis are not England’s only enemy."
