《Worlds of the Imperium》 - 免费有声读物

For Brion Bayard, the discovery of an alternate world to Earth where history took a different turn in the road was not a pleasant experience. His kidnapping brought him some startling revelations. Here was a world in which appeared identical doubles of famous personages—including a dangerous and hated dictator named Brion Bayard! His assignment seemed simple enough.
