The elusive burned man has called on Sam Abel once more. After foiling the plans of the Nazis to ensnare American entrepreneurs in their secret weapon projects, Sam has solidified his place in a shadowy organization tasked with turning the tide of the war. This time, Sam must infiltrate the Nazi establishment in Germany while disguised as one of their own.

A German defector, the enigmatic Sigrid Lang, has conferred slivers of information to British spies embedded in Pforzheim: whispers of the secret weapon known as Erdschlag. Sam must bring her to safety before she will give up all that she knows. Fearing that the massive tank is near completion, Sigrid has warned those who can aid her that it will soon leave its home and point its barrel at London. And capable of blowing Sam’s cover at any moment is Lothar Eichler, bested by Sam during their first rendezvous and now seeing saboteurs in every face. The fearsome man will stop at nothing to ensure his project elevates his stature in the regime.

New renovations have made matters worse: The gargantuan tank doesn’t just fire bunker-busting shells-it has been modified to fire rockets. Running out of time and hiding in plain sight, Sam must bluff his way through enemy territory while ensuring Sigrid’s safety. His enemies are endless, and now, they look just like him. Even under the cover of shadows deep in the Black Forest, he can’t hide for long.
