Nobody saw the Ship A POWERFUL NOVELET by Murray Leinster _It was only a tiny scout ship from somewhere beyond the stars; only one alien creature occupied it. But the ship's mission spelled life to its fellow creatures and death to all living creatures on Earth. And against the super-science of the raider stood one terrified old man and his dog...._ [Transcriber's Note: This etext was produced from Future combined with Science Fiction Stories May-June 1950.

It was armed, of course, but its purpose was not destruction. If this ship, whose entire crew consisted of one individual, were successful in its mission then a great ship would come, wiping out the entire population of cities before anyone suspected the danger. [Illustration: A great ship would come, wiping out the entire population of cities before anyone suspected danger....] But this lone Qul-En was seeking a complex hormone substance which Qul-En medical science said theoretically must exist, but the molecule of which even the Qul-En could not synthesize directly. Yet it had to be found, in great quantity; once discovered, the problem of obtaining it would be taken up, with the resources of the whole race behind it. But first it had to be found. The tiny ship assigned to explore the Solar System for the hormone wished to pass unnoticed. Its mission of discovery should be accomplished in secrecy if possible. For one thing, the desired hormone would be destroyed by contact with the typical Qul-En ray-gun beam, so that normal methods of securing zoological specimens could not be used. The ship winked into being in empty space, not far from Neptune. It drove for that chilly planet, hovered about it, and decided not to land. It sped inward toward the sun and touched briefly on Io, but found no life there. It dropped into the atmosphere of Mars, and did not rise again for a full week, but the vegetation on Mars is thin and the animals mere degenerate survivors of once specialized forms. The ship came to Earth, hovered lightly at the atmosphere's very edge for a long time, and doubtless chose its point of descent for reasons that seemed good to its occupant. Then it landed.
