Keith Laumer Scifi Collection, Greylorn, It Could Be Anything, Gambler's World, Retief

Greylorn - Commander Greylorn must find a lost colony and beg it to come to Earths aid. But before he can accomplish this he must first survive a mutiny aboard his own star ship. A taut story of interplanetary intrigue and adventure!
It Could Be Anything - ?The body shifted, rotating stiffly, then tilted upright. ?The sun struck through the amber shape that flowed down to form itself into the crested wave.? IT COULD BE ANYTHING.
Gambler?s World - Unless Retief and his colleague Magnan get to the bottom of Zorn?s gambling operation and play their own games, a whole spaceship?s worth of diplomats would get their throats cut!
The Yillian Way - Junior Terran diplomat Jame Retief visits a government whose members seem determined to insult their delegation. This?ll take some sharp thinking....
Keith Laumer, well-known for his tales of adventure and action, shows us a different side of his talent in this original, exciting and thought-provoking exploration of the meaning of meaning.
