Randall Garrett had this story first published in Astounding Science Fiction September and October of 1959. His twisted sense of humor and gift for the bizarre situation with believable characters shines here. In the not too distant future, Ken Malone, young but promising FBI agent , is given the most important and difficult assignment of his career: find a spy who is stealing information from the Ultra Top Absolute Secret project to develop a non-rocket space ship at Yucca Flats Labs in Nevada. But this is not a normal spy, this spy laughs at the FBI and all attempts to find him or her because they use an unknown new method to steal the information directly from the minds of the scientists.

An alien crash lands on Earth, and for ten years terrorizes the planet, hiding, periodically killing and eating people and stealing materials for some unknown purpose. The only hope is Bart Stanton, a medically-engineered superman, designed for the sole purpose of confronting the “Nipe”.

Gregg Haljan was aware that there was a certain danger in having the giant spaceship Planetara stop off at the moon to pick up Grantline’s special cargo of moon ore. For that rare metal — invaluable in keeping Earth’s technology running — was the target of many greedy eyes. But nevertheless he hadn’t figured on the special twist the clever Martian brigands would use. So when he found both the ship and himself suddenly in their hands, he knew that there was only one way in which he could hope to save that cargo and his own secret — that would be by turning space-pirate himself and paying the Brigands of the Moon back in their own interplanetary coin.

In effect Professor Newland declared that the curious astronomical phenomena of the previous November--the new "stars" observed, the two meteors that had fallen with their red and green light-fire--were all evidence of the existence of intelligent life on the planet Mercury. (An excerpt from chapter 1. )

There were nine major planets in the Solar System and it was within their boundaries that man first set up interplanetary commerce and began trading with the ancient Martian civilization. And then they discovered a tenth planet--a maverick! This tenth world, if it had an orbit, had a strange one, for it was heading inwards from interstellar space, heading close to the Earth-Mars spaceways, upsetting astronautic calculations and raising turmoil on the two inhabited worlds. But even so none suspected then just how much trouble this new world would make...

In "Tarrano the Conqueror" is presented a tale of the year 2430 A.D.--a time somewhat farther beyond our present-day era than we are beyond Columbus' discovery of America. My desire has been to create for you the impression that you have suddenly been plunged forward into that time--to give you the feeling Columbus might have had could he have read a novel of our present-day life. To this end I have conceived myself a writer of that future time, addressing his contemporary public. You are to imagine...

They got what they wanted--a start on the road to the stars--but no one brought up on Earth could have imagined what was waiting for them Out There!

The Discourse on Method is best known as the source of the famous quotation “cogito ergo sum”, “I think, therefore I am.” …. It is a method which gives a solid platform from which all modern natural sciences could evolve. With this work, the idea of skepticism was revived from the ancients such as Sextus Empiricus and modified to account for a truth that Descartes found to be incontrovertible. Descartes started his line of reasoning by doubting everything, so as to assess the world from a fresh perspective, clear of any preconceived notions.

In preparing these Essays, my chief object has been to present scientific truths in a light and readable form—clearly and simply, but with an exact adherence to the facts as I see them. I have followed—here and always—the rule of trying to explain my meaning precisely as I should wish others to explain, to myself, matters with which I was unfamiliar. Hence I have avoided that excessive simplicity which some seem to consider absolutely essential in scientific essays intended for general perusal, but which is often even more perplexing than a too technical style...
