“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 the 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.”
