It’s 1947 and the war is over, but Juliet Barnard is still tormented by secrets. She was a British agent and wireless operator in occupied Paris until her mission went critically wrong. Juliet was caught by the Germans, imprisoned and tortured in a mansion in Paris’s Avenue Foch.

Now that she’s home, Juliet can’t - or won’t - relive the horrors that occurred in that place. Nor will she speak about Sturmbannführer Strasser, the manipulative Nazi who held her captive…

Haunted by the guilt of betrayal, the last thing Juliet wants is to return to Paris. But when Mac, an SAS officer turned Nazi-hunter, demands her help searching for his sister, Denise, she can’t refuse. Denise and Juliet trained together before being dropped behind enemy lines. Unlike Juliet, Denise never made it home. Certain Strasser is the key to discovering what happened to his sister, Mac is determined to find answers - but will the truth destroy Juliet?
