"The one man who can save Britain from annihilation is held captive in a prisoner of war camp. In the summer of 1940, the war is on a knife-edge. In a world away, a small island has been ravaged with a chemically enhanced strain of the plague. A young boy’s body proves to be the only evidence of this unspeakable Nazi experiment. Archibald Hamilton-Spraggs, Britain’s leading virologist, has been taken prisoner in Germany. Florence and her team face impossible odds to break him out and return him to his lab to create an antidote."
