They talked then, and bit by bit the story came out. The life-form was indeed a virus, unimaginably ancient, and intelligent throughout millions of years of its history. Driven by over-population, a pure culture of the virus-creatures had long ago departed from their original native hosts, and traveled like encapsulated spores across space from a distant galaxy. The trip had been long and exhausting; the virus-creatures had retained only the minimum strength necessary to establish themselves in a new host, some unintelligent creature living on an uninhabited planet, a creature that could benefit by the great intelligence of the virus-creatures, and provide food and shelter for both. Finally, after thousands of years of searching, they had found this planet with its dull-minded, fruit-gathering inhabitants. These creatures had seemed perfect as hosts, and the virus-creatures had thought their long search for a perfect partner was finally at an end.
It was not until they had expended the last dregs of their energy in anchoring themselves into the cells and tissues of their new hosts that they discovered to their horror that the host-creatures could not tolerate them. Unlike their original hosts, the bodies of these creatures began developing deadly antibodies that attacked the virus invaders. In their desperate attempts to hold on and fight back, the virus-creatures had destroyed vital centers in the new hosts, and one by one they had begun to die. There was not enough energy left for the virus-creatures to detach themselves and move on; without some way to stem the onslaught of the antibodies, they were doomed to total destruction.
“We were afraid to tell you doctors the truth,” the spokesman said. “As we wandered and searched we discovered that creatures like ourselves were extreme rarities in the universe, that most creatures similar to us were mindless, unintelligent parasites that struck down their hosts and destroyed them. Wherever we went, life-forms of your kind regarded us as disease-bearers, and their doctors taught them ways to destroy us. We had hoped that from you we might find a way to save ourselves—then you unleashed on us the one weapon we could not fight.”
“But not maliciously,” Dal said. “Only because we did not understand. And now that we do, there may be a way to help. A difficult way, but at least a way. The antibodies themselves can be neutralized, but it may take our biochemists and virologists and all their equipment months or even years to develop and synthesize the proper antidote.”
The spokesman looked at Dal, and turned away with a hopeless gesture. “Then it is too late, after all,” he said. “We are dying too fast. Even those of us who have not been affected so far are beginning to feel the early symptoms of the antibody attack.” He smiled sadly and reached out to stroke the small pink creature on Dal’s arm. “Your people too have a partner, I see. We envy you.”
Dal felt a movement on his arm and looked down at Fuzzy. He had always taken his little friend for granted, but now he thought of the feeling of emptiness and loss that had come across him when Fuzzy had been almost killed. He had often wondered just what Fuzzy might be like if his almost-fluid, infinitely adaptable physical body had only been endowed with intelligence. He had wondered what kind of a creature Fuzzy might be if he were able to use his remarkable structure with the guidance of an intelligent mind behind it....
He felt another movement on his arm, and his eyes widened as he stared down at his little friend.
A moment before, there had been a single three-inch pink creature on his elbow. But now there were two, each just one-half the size of the original. As Dal watched, one of the two drew away from the other, creeping in to snuggle closer to Dal’s side, and a pair of shoe-button eyes appeared and blinked up at him trustingly. But the other creature was moving down his arm, straining out toward the Bruckian spokesman....
Dal realized instantly what was happening. He started to draw back, but something stopped him. Deep in his mind he could sense a gentle voice reassuring him, saying, It’s all right, there is nothing to fear, no harm will come to me. These creatures need help, and this is the way to help them.
He saw the Bruckian reach out a trembling hand. The tiny pink creature that had separated from Fuzzy seemed almost to leap across to the outstretched hand. And then the spokesman held him close, and the new Fuzzy shivered happily.
The virus-creatures had found a host. Here was the ideal kind of body for their intelligence to work with and mold, a host where antibody-formation could be perfectly controlled. Dal knew now that the problem had almost been solved once before, when the virus-creature had reached Fuzzy on the ship; if they had only waited a little longer they would have seen Fuzzy recover from his illness a different creature entirely than before.
Already the new creature was dividing again, with half going on to the next of the Bruckians. To a submicroscopic virus, the body of the host would not have to be large; soon there would be a sufficient number of hosts to serve the virus-creatures’ needs forever. As he started back up the ladder to the ship, Dal knew that the problem on 31 Brucker VII had found a happy and permanent solution.

Back in the control room Dal related what had happened from beginning to end. There was only one detail that he concealed. He could not bring himself to tell Tiger and Jack of the true nature of his relationship with Fuzzy, of the odd power over the emotions of others that Fuzzy’s presence gave him. He could tell by their faces that they realized that he was leaving something out; they had watched him go down to face a blood-thirsty mob, and had seen that mob become docile as lambs as though by magic. Clearly they could not understand what had happened, yet they did not ask him.
“So it was Fuzzy’s idea to volunteer as a new host for the creatures,” Jack said.
Dal nodded. “I knew that he could reproduce, of course,” he said. “Every Garvian has a Fuzzy, and whenever a new Garvian is born, the father’s Fuzzy always splits so that half can join the new-born child. It’s like the division of a cell; within hours the Fuzzy that stayed down there will have divided to provide enough protoplasm for every one of the surviving intelligent Bruckians.”
“And your diagnosis was the right one,” Jack said.
“We’ll see,” Dal said. “Tomorrow we’ll know better.”
But clearly the problem had been solved. The next day there was an excited conference between the spokesman and the doctors on the Lancet. The Bruckians had elected to maintain the same host body as before. They had gotten used to it; with the small pink creatures serving as a shelter to protect them against the deadly antibodies, they could live in peace and security. But they were eager, before the Lancet disembarked, to sign a full medical service contract with the doctors from Hospital Earth. A contract was signed, subject only to final acceptance and ratification by the Hospital Earth officials.
Now that their radio was free again, the three doctors jubilantly prepared a full account of the problem of 31 Brucker and its solution, and dispatched the news of the new contract to the first relay station on its way back to Hospital Earth. Then, weary to the point of collapse, they retired for the first good sleep in days, eagerly awaiting an official response from Hospital Earth on the completed case and the contract.
“It ought to wipe out any black mark Dr. Tanner has against any of us,” Jack said happily. “And especially in Dal’s case.” He grinned at the Red Doctor. “This one has been yours, all the way. You pulled it out of the fire after I flubbed it completely, and you’re going to get the credit, if I have anything to say about it.”
“We should all get credit,” Dal said. “A new contract isn’t signed every day of the year. But the way we all fumbled our way into it, Hospital Earth shouldn’t pay much attention to it anyway.”
But Dal knew that he was only throwing up his habitual shield to guard against disappointment. Traditionally, a new contract meant a Star rating for each of the crew that brought it in. All through medical school Dal had read the reports of other patrol ships that had secured new contracts with uncontacted planets, and he had seen the
