This WWII thriller by an acclaimed historian takes readers inside a secret Nazi weapons lab where treason and conspiracy lead to murder. In a windswept corner of the Third Reich stands the Peenemünde Army Research Center, where German military engineers invent weapons unlike any the world has seen before. Now Otto Fischer, a wounded Luftwaffe officer and former criminal investigator, has been summoned there to solve a seemingly incomprehensible case: the murder of a leading rocket engineer during a devastating air raid. With only days until the SS assume control of the production of a remarkable new weapon, Fischer must find a motive and perpetrator from among several thousand scientists, technicians, soldiers and forced laborers. As he struggles to get the measure of a secretive, brilliant world in which imagination moves far beyond the limits of technology, what at first appears to be a solitary crime draws him into a labyrinth of conspiracy, betrayal and treason.
