The blueskins on Orede could not trust Calhoun, so they pretended not to hear—or maybe they didn't hear. They'd been abandoned and betrayed by all of humanity beyond their world. They'd been threatened and oppressed by guardships in orbit about them, ready to shoot down any space-craft they might send aloft.
So Calhoun pondered ...
A long time later Calhoun heard small sounds which were not normal on a Med Ship in overdrive. They were not part of the random noises carefully generated to keep the silence of the ship endurable. Calhoun raised his head. He listened sharply. No sound could come from outside.
He knocked on the door of the sleeping-cabin. The noises stopped instantly.
"Come out," he commanded through the door.
"I'm—I'm all right," said Maril's voice. But it was not quite steady. She paused. "I was just having a bad dream."
"I wish," said Calhoun, "that you'd tell me the truth occasionally! Come out, please!"
There were stirrings. After a little the door opened and Maril appeared. She looked as if she'd been crying. She said quickly;
"I probably look queer, but it's because I was asleep."
"To the contrary," said Calhoun, fuming, "you've been lying awake crying. I don't know why. I've been out here wishing I could sleep, because I'm frustrated. But since you aren't asleep maybe you can help me with my job. I've figured some things out. For some others I need facts. How about it?"
She swallowed.
"I'll try."
"Coffee?" he asked.
Murgatroyd popped his head out of his miniature sleeping-cabin.
"Chee?" he asked interestedly.
"Go back to sleep!" snapped Calhoun.
He began to pace back and forth.
"I need to know something about the pigment patches," he said jerkily. "Maybe it sounds crazy to think of such things now. First things first, you know. But that is a first thing! So long as Darians don't look like the people of other worlds, they'll be considered different. If they look repulsive, they'll be thought of as evil.... Tell me about those patches. They're different-sized and different-shaped and they appear in different places. You've none on your face or hands, anyhow."
"I haven't any at all," said the girl reservedly.
"I thought—"
"Not everybody," she said defensively. "Nearly, yes. But not all. Some people don't have them. Some people are born with bluish splotches on their skin, but they fade out while they're children. When they grow up they're just like—the people of Weald or any other world. And their children never have them."
Calhoun stared.
"You couldn't possibly be proved to be a Darian, then?"
She shook her head. Calhoun remembered, and started the coffee-maker.
"When you left Dara," he said, "You were carried a long, long way, to some planet where they'd practically never heard of Dara, and where the name meant nothing. You could have settled there, or anywhere else and forgotten about Dara. But you didn't. Why not, since you're not a blueskin?"
"But I am!" she said fiercely. "My parents, my brothers and sisters, and Korvan—."
Then she bit her lip. Calhoun took note but did not comment on the name that she had mentioned.
"Then your parents had the splotches fade, so you never had them," he said absorbedly. "Something like that happened on Tralee, once! There's a virus—a whole group of virus particles! Normally we humans are immune to them. One has to be in terrifically bad physical condition for them to take hold and produce whatever effects they do. But once they're established they're passed on from mother to child.... And when they die out it's during childhood, too!"
He poured coffee for the two of them. As usual, Murgatroyd swung down to the floor and said impatiently;
"Chee! Chee! Chee!"
Calhoun absently filled Murgatroyd's tiny cup and handed it to him.
"But this is marvellous!" he said exuberantly. "The blue patches appeared after the plague, didn't they? After people recovered—when they recovered?"
Maril stared at him. His mind was filled with strictly professional considerations. He was not talking to her as a person. She was purely a source of information.
"So I'm told," said Maril reservedly. "Are there any more humiliating questions you want to ask?"
He gaped at her. Then he said ruefully;
"I'm stupid, Maril, but you're touchy. There's nothing personal."
"There is to me!" she said fiercely. "I was born among blueskins, and they're of my blood, and they're hated and I'd have been killed on Weald if I'd been known as—what I am! And there's Korvan, who arranged for me to be sent away as a spy and advised me to do just what you said,—abandon my home world and everybody I care about! Including him! It's personal to me!"
Calhoun wrinkled his forehead helplessly.
"I'm sorry," he repeated, "Drink your coffee!"
"I don't want it," she said bitterly. "I'd like to die!"
"If you stay around where I am," Calhoun told her, "you may get your wish. All right. There'll be no more questions, I promise."
She turned and moved toward the door to the sleeping-cabin. Calhoun looked after her.
"Maril," he called out to her.
"What?"
"Why were you crying?"
"You wouldn't understand," she said evenly.
Calhoun shrugged his shoulders almost up to his ears. He was a professional man. In his profession he was not incompetent. But there is no profession in which a really competent man tries to understand women. Calhoun annoyedly had to let fate or chance or disaster take care of Maril's personal problems. He had larger matters to cope with.
But he had something to work on, now. He hunted busily in the reference tapes. He came up with an explicit collection of information on exactly the subject he needed. He left the control-room to go down into the storage areas of the Med Ship's hull. He found an ultra-frigid storage box, whose contents were kept at the temperature of liquid air. He donned thick gloves, used a special set of tongs, and extracted a tiny block of plastic in which a sealed-tight phial of glass was embedded. It frosted instantly he took it out, and when the storage-box was closed again the block was covered with a thick and opaque coating of frozen moisture.
He went back to the control-room and pulled down the panel which made available a small-scale but surprisingly adequate biological laboratory. He set the plastic block in a container which would raise it very, very gradually to a specific temperature and hold it there. It was, obviously, a living culture from which any imaginable quantity of the same culture could be bred. Calhoun set the apparatus with great exactitude.
"This," he told Murgatroyd, "may be a good day's work. Now I think I can rest."
Then, for a long while, there was no sound or movement in the Med Ship. The girl Maril may have slept, or maybe not. Calhoun lay relaxed in a chair which at the touch of a button became the most comfortable of sleeping-places. Murgatroyd remained in his cubbyhole, his tail curled over his nose. There were comforting, unheard, easily dismissable murmurings now and again. They kept the feeling of life alive in the ship. But for such infinitesimal stirrings of sound—carefully recorded for this exact purpose—the feel of the ship would have been that of a tomb.
But it was quite otherwise when another ship-day began with the taped sounds of morning activities as faint as echoes but nevertheless establishing an atmosphere of their own.
Calhoun examined the plastic block and its contents. He read the instruments which had cared for it while he slept. He put the block—no longer frosted—in the culture-microscope and saw its enclosed, infinitesimal particles of life in the process of multiplying on the food that had been frozen with them when they were reduced to the spore condition. He beamed. He replaced the block in the incubation oven and faced the day cheerfully.
