John Sewell, the historian, baldly condenses those adventures of a century ago together, but on research and closer scrutiny they take on an individuality and significance deserving of separate treatment, and this they have been given here. For fictionized presentation, we have spaced the adventures into four connected episodes, four acts of a vibrant drama which ranged clear from Saturn to Earth, the core of which was the feud between Captain Carse and the power-lusting Eurasian scientist, Dr. Ku Sui--that feud the reverberations of whose terrible settling still echo over the solar system--and in this last act of the drama, set out below, we come to its spectacular climax.
