FEAR RIDES THE ROCKETS

The Interstellar Medical Service was just about the only remaining galactic organization that every one of the hundreds of inhabited planets respected.  So when their service broke down in Star Sector Twelve, it created a very dangerous situation.

When Calhoun took his Med ship out of overdrive near that sector’s planet Weald, he was vaguely aware of the risks.  But the crisis came home to him with a crash the moment he radioed in for landing coordinates.

“Contamination!  Full mobilization!  Red alert!  Death to blueskins!” Such were the nature of his greetings.

And it began to look like a case of the cosmic jitters that only the most drastic of orbital surgery could cure.

Murray Leinster, whose real name is Will F. Jenkins, has been entertaining the public with his exciting fiction for several decades.  Called the dean of modern science-fiction, he was writing these amazing super-science adventures back in the early twenties before there ever was such a thing as an all-fantasy magazine.  His short stories, novelettes, and serial novels have appeared in most of the major American magazines, both slick and pulp, and many have been reprinted all over the world.  He has made a distinguished name for himself (or rather two names) in the fields of adventure, historical, western, sea, and suspense stories.

Ace Books has still available the following Murray Leinster novels:  CITY ON THE MOON (D-277), THE PIRATES OF ZAN and THE MUTANT WEAPON (D-403), and THE FORGOTTEN PLANET (D-528).
