FLOWER OF DORADIL by John Rackham:
Safari was a planet notorious for its big game. Sportsmen could hunt its montrous progeny on thousands of islands, but not on its single, dark continent, where its native inhabitants were assumed to sleep in primitive ignorance.
Somewhere on that unexplored continent a flower grew whose ichor might cure any human ailment. Someone was exporting the mysterious liquid to Earth, where a few drops of it were priceless, and someone had killed to keep the secret. Four men, all good agents of Interplanetary Security, had been sent to stop the illicit traffic and to discover the source of the flower. None had survived; only one left any clue.
Now one woman, Claire Harper, had been sent. Who were the enemy, where was their lair and how had they remained hidden for so long? With the help of Safari's greatest guide and hunter, she might have a chance to find out, but she would be lucky to see the planet's forbidden continent, much less penetrate to its heart.

A PROMISING PLANET by Jeremy Strike
It was a promising planet, all right. It promised fabulous commissions for Bill Warden, surveyor for Star Systems, Inc. who had made first landing.
It promised a lot, but getting delivery was going to be another story. Because what Bill discovered right off was that this was a very religious planet. If you asked God for something, you either got it - or a direct answer saying why not. If you cursed, you received immediate reprimand. If you prayed, you might get a prompt response.
It was most disconcerting, to say the least, and especially so when the planetary diety decided He did not want any traders leaving the planet - and showed Bill and his rivals that where Almight Power was concerned, it was no mere figure of speech!
