"It is the summer of 1934, and Hitler is nearing the summit of supreme power in Germany. When Britain’s MI6 gets word that a German scientist has made a key breakthrough in germ warfare, they send Elena Standish on a dangerous mission to get him out of Germany before he’s forced to share his knowledge and its destructive power with Hitler’s elite.
But the British soon learn that the new head of Germany’s germ warfare division is an old enemy of Elena's grandfather Lucas, the former head of MI6. And he’s bent on using any means to avenge his defeat at Lucas’s hands twenty years before."
