Retief: Emissary to the Stars — Keith Laumer

THE GROACI PERIL

They're nasty little five-eyed sticky fingers who want the galaxy and will stoop to anything to get it. But when they try to sabotage one planet and use another for their garbage, it's time for Retief, that cunning and courageous emissary from Corps Diplomatique Terrestrienne to smash in.

And smash in Retief does, in an extraordinary series of adventures that take him from gambling to gunplay, from the blue lagoons of the most coveted planet in the solar systems to the aid of one of the loveliest women in the galaxy--and ultimately up against the fiercest and most destructive beings in the Universe!
