 Why didn't the Delegate have a robotic voice?
The DELEGATE FROM VENUS By HENRY SLESAR ILLUSTRATOR NOVICK Everybody was waiting to see what the delegate from Venus looked like. And all they got for their patience was the biggest surprise since David clobbered Goliath. " Let me put it this way," Conners said paternally. One part of his mind wanted him to play it cagey, to behave the way the newspaper wanted him to behave, to protect the cozy Washington assignment he had waited four years to get. "It just seemed strange, all these exchanges of couriers in the past two days. It wasn't the newsmen's jibes that bothered him; it was the certainty that something of major importance was happening in the capitol. There had been hourly conferences at the White House, flying visits by State Department officials, mysterious conferences involving members of the Science Commission. They knew that Senator Spocker, chairman of the Congressional Science Committee, had been involved in every meeting, but Senator Spocker was unavailable. In a secluded booth at the rear of a restaurant unfrequented by newsmen, Greta leaned forward and said: "At first, they thought it was another sputnik." "A spaceship," Greta said coolly, sipping lemonade. "They have been in contact with it now for about three days, and they're thinking of calling a plenary session of the UN just to figure out what to do about it. The only hitch is, Russia doesn't want to wait that long, and is asking for a hurry-up summit meeting to make a decision." "Their delegate. They say that with all the satellites being launched, that our affairs are their affairs, too. The press secretary's secretary, a massive woman with gray hair and impervious to charm, guarded the portals of his office with all the indomitable will of the U. S. Marines. She looked at him with exasperation, and then gathered up a stack of memorandums and letters, his own envelope atop it. I'm just doing my job; I think the public has a right to know about this spaceship that's flying around—" His words brought an exclamation from the others. It's our opinion that secrecy is essential, that leakage of the story might cause panic. Since you're the only unauthorized person who knows of it, we have two choices. But you will not be allowed to relay the story to the press until such a time as all correspondents are informed. That won't give you a 'scoop' if that's what you call it, but you'll be an eyewitness.
 The robot was voiced by Professor Coltz remotely.
