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?'
And he was surprised beyond all reason that he could approach the situation as calmly as he had. In a little while, he knew, when he had time to think it over, he would get the shakes.
'You're a doctor,' said the alien. 'You are a healer of your race.'
'Yes,' said Doc. 'I am one of many healers.'
'You work very hard to make the unwell well. You mend the broken flesh. You hold off death…'
'We try. Sometimes we don't succeed.'
'You have many ailments. You have the cancer and the heart attacks and colds and many other things — I do not find the word.'
'Diseases,' Doc supplied.
'Disease. That is it. You will pardon my shortcomings in the tongue.'
'Let's cut out the niceties,' suggested Doc. 'Let's get on with it.'
'It is not right,' the alien said, 'to have all these diseases. It is not nice. It is an awful thing.'
'We have less than we had at one time. We've licked a lot of them.'
'And, of course,' the alien said, 'you make your living with them.'
'What's that you said!' yelped Doc.
'You will be tolerant of me if I misunderstand. An economic system is a hard thing to get into one's head.'
'I know what you mean,' growled Doc, 'but let me tell you, sir…'
But what was the use of it, he thought. This being was thinking the self-same thing that many humans thought.
'I would like to point out to you,' he said, starting over once again, 'that the medical profession is working hard to conquer those diseases you are talking of. We are doing all we can to destroy our own jobs.'
'That is fine,' the alien said. 'It is what I thought, but it did not square with your planet's business sense. I take it, then, you would not be averse to seeing all disease destroyed.'
'Now, look here,' said Doc, having had enough of it, 'I don't know what you are getting at. But I am hungry and I am tired and if you want to sit here threshing out philosophies…'
'Philosophies,' said the alien. 'Oh, not philosophies. I am practical. I have come to offer an end of all disease.'
They sat in silence for a moment, then Doc stirred half protestingly and said, 'Perhaps I misunderstood you, but I thought you said…'
'I have a method, a development, a find — I do not catch the word — that will destroy all diseases.'
'A vaccine,' said Old Doc.
'That's the word. Except it is different in some ways than the vaccine you are thinking.'
'Cancer?' Doc asked.
The alien nodded. 'Cancer and the common cold and all the others of them. You name it and it's gone.'
'Heart,' said Doc. 'You can't vaccinate for heart.'
'That, too,' the alien said. 'It does not really vaccinate. It makes the body strong. It makes the body right. Like tuning up a motor and making it like new. The motor will wear out in time, but it will function until it is worn out entirely.'
Doc stared hard at the alien. 'Sir,' he said, 'this is not the sort of thing one should joke about.'
'I am not joking,' said the alien.
'And this vaccine — it will work on humans? It has no side effects?'
'I am sure it will. We have studied your — your — the way your bodies work.'
'Metabolism is the word you want.'
'Thank you.' said the alien.
'And the price?' asked Doc.
'There is no price,' the alien said. 'We are giving it to you.'
'Completely free of charge? Surely there must be…'
'Without any charge,' the alien said. 'Without any strings.'
He got up from the chair. He took a flat box from his pocket and walked over to the desk. He placed it upon the desk and pressed its side and the top sprang open. Inside of it were pads — like surgical pads, but they were not made of cloth.
Doc reached out, then halted his hand just above the box.
'May I?' he asked.
'Yes, certainly. You only touch the tops.'
Doc gingerly lifted out one of the pads and laid it on the desk. He kneaded it with a skittish finger and there was liquid in the pad. He could feel the liquid squish as he pressed the pad.
He turned it over carefully and the underside of it was rough and corrugated, as if it were a mouthful of tiny,
