question:  Who are the kind of men who are sent to Sararkkad IV?
context: Every man in the Diplomatic Corps who developed a twitch or a quirk was shipped to Saarkkad IV to work under Bertrand Malloy, Permanent Terran Ambassador to His Utter Munificence, the Occeq of Saarkkad. He trusted no one, and was perpetually on his guard against imaginary plots and persecutions. He was psychologically incapable of making a decision if he were faced with two or more possible alternatives of any major importance. Somewhere out there, the ships of Earth were ranged against the ships of the alien Karna in the most important war that Mankind had yet fought. He was not in the battle line, nor even in the major production line, but it was necessary to keep the drug supply lines flowing from Saarkkad, and that meant keeping on good terms with the Saarkkadic government. For nine years, Bertrand Malloy had been Ambassador to Saarkkad, and for nine years, no Saarkkada had ever seen him. To have shown himself to one of them would have meant instant loss of prestige. The Occeq of Saarkkad himself was never seen except by a handful of picked nobles, who, themselves, were never seen except by their underlings. To violate the rigid social setup of Saarkkad would mean the instant closing off of the supply of biochemical products that the Saarkkadic laboratories produced from native plants and animals—products that were vitally necessary to Earth's war, and which could be duplicated nowhere else in the known universe. It was Bertrand Malloy's job to keep the production output high and to keep the materiel flowing towards Earth and her allies and outposts. A staff of top-grade men could have handled them without half trying. It's inefficient to waste a man on a job that he can do without half trying where there are more important jobs that will tax his full output. Not the worst ones, of course; there were places in the galaxy that were less important than Saarkkad to the war effort. Miss Drayson stood there calmly, her face a mask; her emotions were a secret.
