Of course, there'd always be need of doctors. There'd always be damn fools smashing up their cars and shooting one another and getting fishhooks in their hands and falling out of trees. And there'd always be the babies.

He rocked gently to and fro and thought of all the babies and how some of them had grown until they were men and women now and had babies of their own. And he thought of Martha Anderson, Janet's closest friend, and he thought of old Con Gilbert, as ornery an old shikepoke as ever walked the earth, and tight with money, too. He chuckled a bit wryly, thinking of all the money Con Gilbert finally owed him, never having paid a bill in his entire life.

But that was the way it went. There were some who paid and others who made no pretense of paying, and that was why he and Janet lived in this old house and he drove a five-year car and Janet had worn the selfsame dress to church the blessed winter long.

Although it made no difference, really, once one considered it. For the important pay was not in cash.

There were those who paid and those who didn't pay. And there were those who lived and the other ones who died, no matter what you did. There was hope for some and the ones who had no hope — and some of these you told and there were others that you didn't.

But it was different now.

And it all had started right here in this little town of Millville — not much more than a year ago.

Sitting in the dark, with the lilac scent and the white blush of the bridal wreath and the muted sounds of children clasping to themselves the last minutes of their play, he remembered it.

It was almost 8:30 and he could hear Martha Anderson in the outer office talking to Miss Lane and she, he knew, had been the last of them.

He took off his white jacket, folding it absent-mindedly, fogged with weariness, and laid it across the examination table.

Janet would be waiting supper, but she'd never say a word, for she never had. All these many years she had never said a word of reproach to him, although there had been at times a sense of disapproval at his easy-going ways, at his keeping on with patients who didn't even thank him, much less pay their bills. And a sense of disapproval, too, at the hours he kept, at his willingness to go out of nights when he could just as well have let a call go till his regular morning rounds.

She would be waiting supper and she would know that Martha had been in to see him and she'd ask him how she was, and what was he to tell her?

He heard Martha going out and the sharp click of Miss Lane's heels across the outer office. He moved slowly to the basin and turned on the tap, picking up the soap.

He heard the door creak open and did not turn his head. "Doctor," said Miss Lane, "Martha thinks she's fine. She says you're helping her. Do you think…"

"What would you do," he asked.

"I don't know," she said.

Would you operate, knowing it was hopeless? Would you send her to a specialist, knowing that he couldn't help her, knowing she can't pay him and that she'll worry about not paying? Would you tell her that she has, perhaps, six months to live and take from her the little happiness and hope she still has left to her?"

"I am sorry, doctor."

"No need to be. I've faced it many times. No case is the same. Each one calls for a decision of its own. It's been a long, hard day…"

"Doctor, there's another one out there."

"Another patient?"

"A man. He just came in. His name is Harry Herman."

"Herman? I don't know any Hermans."

"He's a stranger," said Miss Lane. "Maybe he just moved into town."

"If he'd moved in," said Doc, "I'd have heard of it. I hear everything."

"Maybe he's just passing through. Maybe he got sick driving on the road."

"Well, send him in," said Doc, reaching for a towel. "I'll have a look at him."

The nurse turned to the door.

"And Miss Lane."

"Yes?"

"You may as well go home. There's no use sticking round. It's been a real bad day."

And it had been, at that, he thought. A fracture, a burn, a cut, a dropsy, a menopause, a pregnancy, two pelvics, a scattering of colds, a feeding schedule, two teethings, a suspicious lung, a possible gallstone, a cirrhosis of the liver and Martha Anderson. And now, last of all, this man named Harry Herman — no name that he knew and when one came to think of it, a rather funny name.

And he was a funny man. Just a bit too tall and willowy to be quite believable, ears too tight against his skull, lips so thin they seemed no lips at all.

"Doctor?" he asked, standing in the doorway.

"Yes," said Doc, picking up his jacket and shrugging into it. "Yes, I am the doctor. Come on in. What can I do for you?"

"I am not ill," said the man.

"Not ill?"

"But I want to talk to you. You have time, perhaps?"

"Yes, certainly," said Doc, knowing that he had no time and resenting this intrusion. "Come on in. Sit down."

He tried to place the accent, but was unable to. Central European, most likely.

"Technical," said the man. "Professional."

"What do you mean?" asked Doc, getting slightly nettled.

"I talk to you technical. I talk professional."

"You mean that you're a doctor?"

"Not exactly," said the man, "although perhaps you think so. I should tell you immediate that I am an alien."

"An alien," said Old Doc. "We've got lots of them around. Mostly refugees."

"Not what I mean. Not that kind of alien. From some other planet. From some other star."

"But you said your name was Herman…"

"When in Rome," said the other one, "you must do as Romans."

"Huh?" asked Doc, and then: "Good God, do you mean that? That you are an alien. By an alien, do you mean…"

The other nodded happily. "From some other planet. From some other star. Very many light-years."

"Well, I'll be damned," said Doc.

He stood there looking at the alien and the alien grinned back at him, but uncertainly.

"You think, perhaps," the alien said, "but he is so human!"

"That," said Doc, "was going through my mind."

"So you would have a look, perhaps. You would know a human body."

"Perhaps," said Doc grimly, not liking it at all. "But the human body can take some funny turns."

"But not a turn like this," said the stranger, showing him his hands.

"No," said the shocked old Doc. "No such turn as that." For the hand had two thumbs and a single finger, almost as if a bird claw had decided to turn into a hand.

"Nor like this?" asked the other, standing up and letting down his trousers.

"Nor like that," said Doc, more shaken than he'd been in many years of practice.

"Then," said the alien, zipping up his trousers, "I think that it is settled."

He sat down again and calmly crossed his knees, "If you mean I accept you as an alien," said Doc, "I suppose I do. Although it's not an easy thing."

"I suppose it is not. It comes as quite a shock."

Doc passed a hand across his brow. "Yes, a shock, of course. But there are other points…"

"You mean the language," said the alien. "And my knowledge of your customs."

"That's part of it, naturally."

"We've studied you," the alien said. "We've spent some time on you. Not you alone, of course…"

"But you talk so well," protested Doc. "Like a well-educated foreigner."

"And that, of course," the other said, "is what exactly I am."

"Why, yes, I guess you are," said Doc. "I hadn't thought of it."

"I am not glib," said the alien. "I know a lot of words, but I use them incorrect. And my vocabulary is restricted to just the common speech. On matters of great technicality, I will not be proficient."

Doc walked around behind his desk and sat down rather limply.

"All right," he said, "let's have the rest of it. I accept you as an alien. Now tell me the other answer. Just why are you here?"
