A hidden Nazi fortune. A disgraced Bletchley clerk. A mission no trained agent could survive.

In the ruins of post-war Europe, Sophie Faulkner only wants the past to leave her alone.

Once a gifted German-speaking clerk at Bletchley Park, Sophie’s life was destroyed when British intelligence uncovered the truth she had tried to bury: she was born Sophie von Adler, daughter of a wealthy Nazi industrialist. Interrogated, imprisoned, disgraced, and abandoned, she has survived the war with nothing but a ruined reputation and a talent for keeping secrets.

Then MI5 offers her a way back.

Her father’s hidden fortune lies in a Zurich bank account — millions in Swiss francs and bearer bonds intended to finance the escape of senior Nazis fleeing Allied justice. To reach it, Sophie must become the woman Europe’s most dangerous men expect to see: the cold, entitled heiress of a dead Reich loyalist.

But the money is only bait.

Drawn into a shadow war between British intelligence, American pragmatists, Vatican fixers, Swiss bankers, Soviet agents, and the remnants of the SS, Sophie finds herself trapped inside the very network she was sent to expose. Every alliance is temporary. Every identity is a weapon. And if the men around her discover where her loyalties truly lie, she will not live long enough to choose her own future.
