London, 1940: Farmer John Cook would rather avoid the city at the best of times. But as he watches Nazi bombers passing overhead in the moonlight, he knows he is exactly where he needs to be.

A young woman has disappeared during an air raid and Cook links her to a network of spies. As his search continues, he realises more is at stake than he could have imagined...

Occupied France: Lady Margaret is playing a dangerous game. To the German high-command she is a valuable prize. To the British, she has become the enemy, unless she can do the impossible: gain the trust of those at the heart of the Nazi war machine and betray their secrets.

With the fate of Europe in their hands, will Cook and Margaret make the ultimate sacrifice to keep each other's secrets safe and save innocent lives?
