Among the heroes of the pulps who soared through their adventures, G-8 flew higher and farther than any of his contemporaries. His true name unknown, the Flying Spy was no mere flyboy, but the champion ace of World War I.

As one of Popular’s star writers, Robert J. Hogan was the writer who publisher Harry Steeger selected for a suitable scribe. Steeger and Hogan hashed out an idea. It was part Eddie Rickenbacker and part What Price Glory?—which was a popular Maxwell Anderson stage play turned into a motion picture. Price stressed the horrors of war as counterpoint to the sentimental comradeship of the Allies in the trenches. Only in this case, by horror, Popular Publications meant something far more horrific than mustard-gas trench warfare atrocities.

It all began with a message dropped from a raiding German plane on G-8‘s headquarters, a warning that promised a new kind of war and demanded unconditional surrender.

“Tomorrow at dawn von Griel will fly again. He has been brought back to life. All other German aces who have been killed will be brought back to live again in the air, by the aid of a new white magic.”

The next day, G-8 and his Battle Aces encountered Oberleutnant von Griel in the sky—cold-eyed and stiff, yet flying his checkered Fokker. Worse, he was impervious to their bullets! This is only the beginning of the wave of Zombie Hun pilots, reanimated by the foul sorcery of Haitian Voodoo––the Squadron of Corpses!

How can the Master Spy repel an onslaught of the living dead? For not even G-8 understood how foes he had shot down in past battles could live again to fly against him and his fellow Allied pilots.
