The world thought aviator Tom Franklin was dead. Years before, he had set out on a pioneering transpacific flight alone — and vanished. When he returned, as if from the dead, he and a mysterious woman flew a battered plane that had been repaired with plates of pure gold. Desperately seeking the help of Doc Savage, the mighty Man of Bronze, Franklin and his curvaceous charge fall into the clutches of the diamond smuggler Blackbird Hinton and his cutthroat crew — but not before the bronze adventurer hears of their difficulty. There ensues a quest as dangerous as any in recorded history. One that will embroil the compassionate yet hard-fisted Doc Savage and his men in a raging battle for control of one of history’s most closely guarded mysteries. The lost secret of Python Isle!
From an interview with Will Murray:
How detailed are the outlines Lester Dent left behind?
They varied. The first one, “Python Isle,” was the only complete outline that was completely rejected and never used. It was I think 10, 12 pages long, in chapters, so that was a joy to work with. In fact, that was the first novel I ever wrote. Sometimes the premises are as short as a page or even a paragraph. I think I have one that’s just a paragraph long, but it’s a good paragraph. It’s an interesting paragraph. It’s a provocative thing, and then I’d have to build from that.
