The mad Marquis de Saint-Imier attempts to blackmail France and install a reign of mass terror through his control of atomic forces and electromagnetic waves. But against him stand the indomitable Professor Mazelier and his assistant Monsieur Gribal. Who will prevail in the ultimate battle against the Radio-Terror? Eugène Thébault's Radio-Terror (1929) had the honor of being one of the very few French works selected by Hugo Gernsback to be translated by none other than Fletcher Pratt, the well-known author of The Well of the Unicorn, and it was published in 1933 in Wonder Stories. This new edition includes Frank R. Paul's original illustrations and an introduction by SF scholar Jean-Marc Lofficier.
