D-99 [EPUB ebook] 

ROCKETS SLAMMED PAST
—just missing the tall, gaunt man who dodged down the stairs of the Earth Embassy. A figure loomed in a doorway and he snapped off a quick blaster shot at it—missed.
He’d killed one man, wounded others—and was carrying papers stolen from the secret Embassy files. They had to stop him—but they couldn’t!
—And, worlds away, the men of Department 99 watched on their galaxy-spanning view-screen … knowing they were responsible for this disaster—and powerless to do anything about it!

O autorze

(1918-1997) US author whose first sf story, 'Locked Out’, appeared in Astounding in February 1940, but who became fully active, mainly with further stories in Astounding though with appearances in most other SF Magazines, only after army service in World War Two. By 1967, when he became inactive, he had published nearly 60 stories. His five Bureau of Slick Tricks tales, beginning with 'Bureau of Slick Tricks’ (December 1948 Astounding) and continuing in Astounding to March 1952, are typical of John W Campbell Jr’s fondness for stories in which humans deftly outwit thick-skulled (often bureaucratic) Aliens; here the B ST, officially the Bureau of Special Trading, specializes in leveraging Terra’s position as a hub of interstellar trade to keep aliens happy and trading via Terran-controlled space. In Fyfe’s thematically similar novel, D-99 (fixup 1962), Department 99 of the Terran government has the job of finagling citizens out of jams on other planets when conventional diplomatic approaches have failed, and generally flummoxing thicker species. The tone is fortunately light.
