The third book in this series of World War II spy novels follows fearless, libidinous secret agents Major Richard Caniday and Eric Fulmar on their dangerous mission to save the life of a scientist and his enticing daughter. While the Nazis are holding the scientist captive for his expert assistance in the Third Reich's development of jet engines, their motives for holding the voluptuous lass are entirely sexual. A separate plot line takes readers from Germany to Morocco, where Fulmar attacks an assignment related to the Allies' attempt to create their own version of the flying bomb. Historical luminaries, such as William Wild Bill Donovan, Joseph P. Kennedy Jr., and David Niven, add glimmer to the action.
