Retief: Ambassador to Space: Seven Incidents of the Corps Diplomatique Terrestrienne [EPUB ebook] 

How are thing on Rockamorra? Bad, very. Earth Ambassador Pinchbottle has contracted to fight a dinosaur, and it’s up to troubleshooter Jame Retief to keep him from being stomped, mangled, or eaten.Things are tough on other planets, too, with a civil war on Skweem, a dying race om Sulinore, and mudstorms on Schweinhund’s World.These seven stories show the Galaxy’s hippest diplomat at his unexpected and jaunty best.
