However, she did sufficiently understand the problems with the Beta procedure and the Syndrome, so he had to flirt back. She had to be kept on the reservation. Feign an interest but not enough for it to go anywhere. "Deb, she's just an ideal fit for the study, that's all. Nothing more." The stem cell procedure for her stenosis should go forward with only minimal risk. There was every reason to hope he could rejuvenate the tissue in Alexa's left ventricle. It was merely an extrapolation of the kind of heart procedure that had worked such a wonder for Emma Rosen. The real challenge was simultaneously attempting the Beta- related procedure. The trick was to stimulate the development of antibodies through a moderate dosage of the special Beta enzyme, tempering it enough that it didn't go critical and begin replicating uncontrollably, the way it had in Kristen, and (probably) very soon in W.B. Not so low as to be inoperative but not so high that it would go out of control. The "Goldilocks dosage," not too much, not too little. The problem was, he wasn't absolutely sure what that dosage was. Should he tell Alexa Hampton the full story about what he was doing? About the Beta? That ethical question, he had decided, he would leave to Grant Hampton, Bartlett's hustler of a CFO. It was his sister, after all. Presumably, he'd tell her whatever she needed to know to make an informed decision. Let the responsibility be on his head. The phone on his desk finally rang. Chapter 10 _Monday, April 6 12:57 P.M. _ Stone Aimes was floating through cyberspace, through the massive data pages of the National Institutes of Health. Since the Gerex Corporation had a complete clampdown on their clinical-trial results, he was attempting an end run. By going to the source, he was hoping he could find out whether or not Karl Van de Vliet's experiments with stem cell technology were succeeding. He needed that information to finish his book, and he hoped that the remainder of the advance could be used to pay for his daughter Amy's private school in New York, if he got it in time. He was dreaming of a life in which she could come back to live with him at least part of the year. Sometimes, particularly days like this--Monday was his official day off--he couldn't avoid the fact he was incredibly lonely. But first things first He had gone to the section that described the many and varied clinical trials the NIH had under way. Then he used "scrambled eggs," the entry protocol given to him by Dale Coverton, to circumvent security on the site and get him into the second-level NIH data files. He was hoping to find the names of patients who had gone through the Gerex stem cell procedure and could be interviewed.
