"But they do! At least to me, they do," Dal said. "I've always wanted to be a doctor. There's nothing else I want to do. To work at home, among my people."
"There was a plague on Garv II, wasn't there?" Doctor Arnquist said. "A cyclic thing that came back again and again. The cycle was broken just a few years ago, when the virus that caused it was finally isolated and destroyed."
"By the physicians of Hospital Earth," Dal said.
"It's happened again and again," the Black Doctor said. "We've seen the same pattern repeated a thousand times across the galaxy, and it has always puzzled us, just a little." He smiled. "You see, our knowledge and understanding of the life sciences here on Earth have always grown hand in hand with the physical sciences. We had always assumed that the same thing would happen on any planet where a race has developed intelligence and scientific methods of study. We were wrong, of course, which is the reason for the existence of Hospital Earth and her physicians today, but it still amazes us that with all the technology and civilization in the galaxy, we Earthmen are the only people yet discovered who have developed a broad knowledge of the processes of life and illness and death."
The old man looked up at his visitor, and Dal felt his pale blue eyes searching his face. "How badly do you want to be a doctor, Dal?"
"More than anything else I know," Dal said.
"Badly enough to do anything to achieve your goal?"
Dal hesitated, and stroked Fuzzy's head gently. "Well ... almost anything."
The Black Doctor nodded. "And that, of course, is the reason I had to see you before this interview, my friend. I know you've played the game straight right from the beginning, up to this point. Now I beg of you not to do the thing that you are thinking of doing."
For a moment Dal just stared at the little old man in black, and felt the fur on his arms and back rise up. A wave of panic flooded his mind. He knows! he thought frantically. He must be able to read minds! But he thrust the idea away. There was no way that the Black Doctor could know. No race of creatures in the galaxy had that power. And yet there was no doubt that Black Doctor Arnquist knew what Dal had been thinking, just as surely as if he had said it aloud.
