But his progress was somewhat slower than he'd anticipated though it seemed to satisfy the doctor who went on with his experiments. The offending bacteria could be killed electrically. But the current was dangerously large and there was no practical way to apply the treatment to humans. The animal was the only effective method.
Kessler discovered the microbe required an intermediate host. A tick or a mosquito seemed indicated. It would take a protracted search of the mountains to determine just what insect was the carrier. In any event the elaborate sanitary precautions were unnecessary. Microscreens came down and decontagion suits were no longer worn. Bolden could not pass the disease on to anyone else.
Neither could the animal. It seemed wholly without parasites. It was clean and affectionate, warm to the touch. Bolden was fortunate that there was such a simple cure for the most dreaded disease on Van Daamas.
It was several days before he was ready to leave the small hospital at the edge of the settlement. At first he sat up in bed and then he was allowed to walk across the room. As his activity increased, the animal became more and more content to lie on the bed and follow him with its eyes. It no longer frisked about as it had in the beginning. As Bolden told the nurse, it was becoming housebroken.
The time came when the doctor failed to find a single microbe. Bolden's newly returned strength and the sensitivity of his skin where before there had been numbness confirmed the diagnosis. He was well. Peggy came to walk him home. It was pleasant to have her near.
"I see you're ready," she said, laughing at his eagerness.
"Except for one thing," he said. "Come, Pet." The animal raised its head from the bed where it slept.
"Pet?" she said quizzically. "You ought to give it a name. You've had it long enough to decide on something."
"Pet's a name," he said. "What can I call it? Doc? Hero?"
