Chapter V: The surviving man from the Golden City was tortured by a mob of half-naked renegades. The prisoner was a brave man, though, he presently flung back his head and set his teeth. He stilled his writhings, and looked at his captors with a grim and desperate defiance. Then Smithers stumbled away from the eye-piece, dry-throated with terrorated terror.
