It is February 1940, and England is desperate to find out when and how Hitler will make his move west toward France. A young sleeper agent named Eva Bernhardt, seduced into spydom by a roguish M16 agent named Hobbs, comes into possession of a vital piece of information and makes a run for it. But the Germans are on to her quickly - too quickly. Was her source compromised? Was that Hobbs she just saw in the street? Who are those other men shadowing her - or are they? In a lethal game of ruse and counterruse, the British and Germans engage in a war of intelligence, each side testing the other, searching for advantage, but there are some things even spymasters cannot control. Uncertain whom to trust, whether she is racing to her safety or to her death, Eva Bernhardt is about to take her future into her own hands - and with it, perhaps the future of the entire war.
