The Best of Nancy Kress (76 page)

“Sleep served an important evolutionary function. Once Clem Pre-Mammal was done filling his stomach and squirting his sperm around, sleep kept him immobile and away from predators. Sleep was an aid to survival. But now it’s a leftover mechanism, a vestige like the appendix. It switches on every night, but the need is gone. So we turn off the switch at its source, in the genes.”

Ong winced. He hated it when she oversimplified like that. Or maybe it was the lightheartedness he hated. If Marsteiner were making this presentation, there’d be no Clem Pre-Mammal.

Camden said, “What about the need to dream?”

“Not necessary. A leftover bombardment of the cortex to keep it on semi-alert in case a predator attacked during sleep. Wakefulness does that better.”

“Why not have wakefulness instead then? From the start of the evolution?”

He was testing her. Susan gave him a full, lavish smile, enjoying his brass. “I told you. Safety from predators. But when a modern predator attacks—say, a cross-border data-atoll investor—it’s safer to be awake.”

Camden shot at her, “What about the high percentage of REM sleep in fetuses and babies?”

“Still an evolutionary hangover. Cerebrum develops perfectly well without it.”

“What about neural repair during slow-wave sleep?”

“That does go on. But it can go on during wakefulness, if the DNA is programmed to do so. No loss of neural efficiency, as far as we know.”

“What about the release of human growth enzyme in such large concentrations during slow-wave sleep?”

Susan looked at him admiringly. “Goes on without the sleep. Genetic adjustments tie it to other changes in the pineal gland.”

“What about the—”

“The
side effects
?” Mrs. Camden said. Her mouth turned down. “What about the bloody side effects?”

Susan turned to Elizabeth Camden. She had forgotten she was there. The younger woman stared at Susan, mouth turned down at the corners.

“I’m glad you asked that, Mrs. Camden. Because there are side effects.” Susan paused; she was enjoying herself. “Compared to their age mates, the nonsleep children—who have
not
had IQ genetic manipulation—are more intelligent, better at problem-solving, and more joyous.”

Camden took out a cigarette. The archaic, filthy habit surprised Susan. Then she saw that it was deliberate: Roger Camden was drawing attention to an ostentatious display to draw attention away from what he was feeling. His cigarette lighter was gold, monogrammed, innocently gaudy.

“Let me explain,” Susan said. “REM sleep bombards the cerebral cortex with random neural firings from the brain stem; dreaming occurs because the poor besieged cortex tries so hard to make sense of the activated images and memories. It spends a lot of energy doing that. Without that energy expenditure, nonsleep cerebrums save the wear-and-tear and do better at coordinating real-life input. Thus, greater intelligence and problem-solving.

“Also, doctors have known for sixty years that antidepressants, which lift the mood of depressed patients, also suppress REM sleep entirely. What they have proved in the past ten years is that the reverse is equally true: suppress REM sleep and people don’t
get
depressed. The nonsleep kids are cheerful, outgoing…
joyous
. There’s no other word for it.”

“At what cost?” Mrs. Camden said. She held her neck rigid, but the corners of her jaw worked.

“No cost. No negative side effects at all.”

“So far,” Mrs. Camden shot back.

Susan shrugged. “So far.”

“They’re only four years old! At the most!”

Ong and Krenshaw were studying her closely. Susan saw the moment the Camden woman realized it; she sank back into her chair, drawing her fur coat around her, her face blank.

Camden did not look at his wife. He blew a cloud of cigarette smoke. “Everything has costs, Dr. Melling.”

She liked the way he said her name. “Ordinarily, yes. Especially in genetic modification. But we honestly have not been able to find any here, despite looking.” She smiled directly into Camden’s eyes. “Is it too much to believe that just once the universe has given us something wholly good, wholly a step forward, wholly beneficial? Without hidden penalties?”

“Not the universe. The intelligence of people like you,” Camden said, surprising Susan more than anything else that had gone before. His eyes held hers. She felt her chest tighten.

“I think,” Dr. Ong said dryly, “that the philosophy of the universe may be beyond our concerns here. Mr. Camden, if you have no further medical questions, perhaps we can return to the legal points Ms. Sullivan and Mr. Jaworski have raised. Thank you, Dr. Melling.”

Susan nodded. She didn’t look again at Camden. But she knew what he said, how he looked, that he was there.

The house was about what she had expected, a huge mock-Tudor on Lake Michigan north of Chicago. The land was heavily wooded between the gate and the house, open between the house and the surging water. Patches of snow dotted the dormant grass. Biotech had been working with the Camdens for four months, but this was the first time Susan had driven to their home.

As she walked toward the house, another car drove up behind her. No, a truck, continuing around the curved driveway to a service entry at the side of the house. One man rang the service bell; a second began to unload a plastic-wrapped playpen from the back of the truck. White, with pink and yellow bunnies. Susan briefly closed her eyes.

Camden opened the door himself. She could see his effort not to look worried. “You didn’t have to drive out, Susan; I’d have come into the city!”

“No, I didn’t want you to do that, Roger. Mrs. Camden is here?”

“In the living room.” Camden led her into a large room with a stone fireplace, English country-house furniture, and prints of dogs or boats, all hung eighteen inches too high; Elizabeth Camden must have done the decorating. She did not rise from her wing chair as Susan entered.

“Let me be concise and fast,” Susan said, “I don’t want to make this anymore drawn-out for you than I have to. We have all the amniocentesis, ultrasound, and Langston test results. The fetus is fine, developing normally for two weeks, no problems with the implant on the uterine wall. But a complication has developed.”

“What?” Camden said. He took out a cigarette, looked at his wife, and put it back unlit.

Susan said quietly, “Mrs. Camden, by sheer chance both your ovaries released eggs last month. We removed one for the gene surgery. By more sheer chance the second was fertilized and implanted. You’re carrying two fetuses.”

Elizabeth Camden grew still. “Twins?”

“No,” Susan said. Then she realized what she had said. “I mean, yes. They’re twins, but non-identical. Only one has been genetically altered. The other will be no more similar to her than any two siblings. It’s a so-called normal baby. And I know you didn’t want a so-called normal baby.”

Camden said, “No. I didn’t.”

Elizabeth Camden said, “I did.”

Camden shot her a fierce look that Susan couldn’t read. He took out the cigarette again, and lit it. His face was in profile to Susan, and he was thinking intently; she doubted he knew the cigarette was there, or that he was lighting it. “Is the baby being affected by the other one’s being there?”

“No,” Susan said. “No, of course not. They’re just…coexisting.”

“Can you abort it?”

“Not without aborting both of them. Removing the unaltered fetus would cause changes in the uterine lining that would probably lead to a spontaneous miscarriage of the other.” She drew a deep breath. “There’s that option, of course. We can start the whole process over again. But as I told you at the time, you were very lucky to have the
in vitro
fertilization take on only the second try. Some couples take eight or ten tries. If we started all over, the process could be a lengthy one.”

Camden said, “Is the presence of this second fetus harming my daughter? Taking away nutrients or anything? Or will it change anything for her later on in the pregnancy?”

“No. Except that there is a chance of premature birth. Two fetuses take up a lot more room in the womb, and if it gets too crowded, birth can be premature. But the—”

“How premature? Enough to threaten survival?”

“Most probably not.”

Camden went on smoking. A man appeared at the door. “Sir, London calling. James Kendall for Mr. Yagai.”

“I’ll take it.” Camden rose. Susan watched him study his wife’s face. When he spoke, it was to her. “All right, Elizabeth. All right.” He left the room.

For a long moment the two women sat in silence. Susan was aware of disappointment; this was not the Camden she had expected to see. She became aware of Elizabeth Camden watching her with amusement.

“Oh, yes, Doctor. He’s like that.”

Susan said nothing.

“Completely overbearing. But not this time.” She laughed softly, with excitement. “Two. Do you…do you know what sex the other one is?”

“Both fetuses are female.”

“I wanted a girl, you know. And now I’ll have one.”

“Then you’ll go ahead with the pregnancy.”

“Oh, yes. Thank you for coming, Doctor.”

She was dismissed. No one saw her out. But as she was getting into her car, Camden rushed out of the house, coatless. “Susan! I wanted to thank you. For coming all the way out here to tell us yourself.”

“You already thanked me.”

“Yes. Well. You’re sure the second fetus is no threat to my daughter?”

Susan said deliberately, “Nor is the genetically altered fetus a threat to the naturally conceived one.”

He smiled. His voice was low and wistful. “And you think that should matter to me just as much. But it doesn’t. And why should I fake what I feel? Especially to you?”

Susan opened her car door. She wasn’t ready for this, or she had changed her mind, or something. But then Camden leaned over to close the door, and his manner held no trace of flirtatiousness, no smarmy ingratiation. “I better order a second playpen.”

“Yes.”

“And a second car seat.”

“Yes.”

“But not a second night-shift nurse.”

“That’s up to you.”

“And you.” Abruptly he leaned over and kissed her, a kiss so polite and respectful that Susan was shocked. Neither lust nor conquest would have shocked her; this did. Camden didn’t give her a chance to react; he closed the car door and turned back toward the house. Susan drove toward the gate, her hands shaky on the wheel until amusement replaced shock: It
had
been a deliberate, blatant, respectful kiss, an engineered enigma. And nothing else could have guaranteed so well that there would have to be another.

She wondered what the Camdens would name their daughters.

Dr. Ong strode the hospital corridor, which had been dimmed to half-light. From the nurse’s station in Maternity a nurse stepped forward as if to stop him—it was the middle of the night, long past visiting hours—got a good look at his face, and faded back into her station. Around a corner was the viewing glass to the nursery. To Ong’s annoyance, Susan Melling stood pressed against the glass. To his further annoyance, she was crying.

Ong realized that he had never liked the woman. Maybe not any women. Even those with superior minds could not seem to refrain from being made damn fools by their emotions.

“Look,” Susan said, laughing a little, swiping at her face. “Doctor—
look
.”

Behind the glass Roger Camden, gowned and masked, was holding up a baby in a white undershirt and pink blanket. Camden’s blue eyes—theatrically blue—a man really should not have such garish eyes—glowed. The baby’s head was covered with blond fuzz; it had wide eyes and pink skin. Camden’s eyes above the mask said that no other child had ever had these attributes.

Ong said, “An uncomplicated birth?”

“Yes,” Susan Melling sobbed. “Perfectly straightforward. Elizabeth is fine. She’s asleep. Isn’t she beautiful? He has the most adventurous spirit I’ve ever known.” She wiped her nose on her sleeve; Ong realized that she was drunk. “Did I ever tell you that I was engaged once? Fifteen years ago, in med school? I broke it off because he grew to seem so ordinary, so boring. Oh, God, I shouldn’t be telling you all this. I’m sorry. I’m sorry.”
