It is summer 1943. Two of the allies' most important plans are at grave risk--Operation Overlord's invasion of France and the Manhattan Project's race to build the atomic bomb. President Roosevelt turns to OSS spy chief Wild Bill Donovan--and Donovan turns to Dick Canidy and his teams behind enemy lines. They must fight the Axis to sabotage Germany's new "aerial torpedo" rockets; to rescue a missing covert OSS team; and to exploit German intelligence agents and generals disgruntled enough with Hitler to try to topple him. And they must battle the enemy within: The Soviets are using moles to steal Manhattan Project secrets.
