  In the early part of the Twenty Second Century, Dr. Richard Arcot, hailed as "the greatest living physicist", and Robert Morey, his brilliant mathematical assistant, discovered the so-called "molecular motion drive", which utilized the random energy of heat to produce useful motion. John Fuller, designing engineer, helped the two men to build a ship which used the drive in order to have a weapon to seek out and capture the mysterious Air Pirate whose robberies were ruining Transcontinental Airways. The Pirate, Wade, was a brilliant but neurotic chemist who had discovered, among other things, the secret of invisibility. Cured of his instability by modern psychomedical techniques, he was hired by Arcot to help build an interplanetary vessel to go to Venus. The Venusians proved to be a humanoid race of people who used telepathy for communication. Although they were The Black Star, Nigra, was a dead, burned-out sun surrounded by a planetary system very much like our own. But these people had been forced to use their science to produce enough heat and light to stay alive in the cold, black depths of interstellar space. There was nothing evil or menacing in their attack on the Solar System; they simply wanted a star that gave off light and heat. So they attacked, not realizing that they were attacking beings equal in intelligence to themselves. They were at another disadvantage, too. The Nigrans had spent long millennia fighting their environment and had had no time to fight among themselves, so they knew nothing of how to wage a war. The Earthmen and Venusians knew only too well, since they had a long history of war on each planet. Inevitably, the Nigrans were driven back to the Black Star. The war was over. And things became dull. And the taste of adventure still remained on the tongues of Arcot, Wade, and Morey. |
