Emma Cameron is a Melbourne doctor juggling a busy career and a crumbling marriage. Then one day she goes to visit her parents after work and finds her father dead and her mother beaten and shocked into silence. Police suggest a possible connection to two recent attacks on elderly men. It all seems utterly unreal.
On the day of the funeral a stranger attends, and reveals that her South African father had actually been a German soldier in the war. Jacob Rabin, a lawyer, Nazi hunter, and the son of a survivor with his own connection to William Brock, persuades Emma that there are enough differences between her father's case and the killer the police are tracking, to warrant a trip to Europe and a search back through time.
Between the remnants of the French Resistance, British Intelligence and the German Army, Emma and Jake unravel a world where allies could betray you while enemies became friends. Slowly, as William Brock's life becomes clearer, an enemy appears out of the shadows who may now threaten Emma's own safety.
