What he didn't say was on both their minds: what about Bartlett himself? After Kristen Starr had had the Beta, and it had seemed successful, Bartlett decided to have it too. Now his daily blood tests here at the institute were showing that the telomerase enzyme was starting to metastasize and replicate in his bloodstream, just as it had in hers.

"Well," Bartlett went on, "Karl thinks he's got a new idea that might save us. Hampton is supposed to be on the case this very morning." He stared out the chopper's window, down at the rooftops of his empire. At the north end of the industrial park was the main laboratory, where stents and titanium joint replacements were tested on animals—mostly sterile pigs, though some primate testing also was under way. The central area had two large manufacturing facilities where the more complex devices were made.

The buildings were all white cinder block, except for the one they were hovering above now. It was at the far south end, a massive three‑story mansion nestled among ancient pines and reached by a long cobblestone driveway. Though it was actually the oldest building of the group by a hundred years, it was the latest acquisition for the complex. It fronted a beautiful ten‑acre lake, and had been a summer palacio of a nineteenth‑century railroad baron. Around mid‑century it was turned into a luxury retirement home, complete with nursing services. Its ornate appointments reminded patients of the Frick Gallery, if one could imagine those marble halls teeming with wheelchairs and nurses.

Bartlett had bought the defunct manufacturing complex next to it eighteen years earlier for the BMD industrial park, but it was only six years ago that the owners of the mansion, a group of squabbling heirs, finally relented and agreed to part with the property. It was now a flagship holding of BMD.

He had an eye for design and he had loved remodeling the old mansion and making it into a modern clinic and research facility. He had renamed it the Dorian Institute and moved in Karl Van de Vliet and the research staff of the Gerex Corporation. He also had put a landing pad on the expansive roof, along with a stair leading down to an elevator that could take him directly to the laboratory in the basement.

Kenji Noda settled the McDonnell Douglas onto the pad and cut the engines. Bartlett never let himself worry about the noise. The patients in the clinical trials were here at no charge, so they really couldn't complain, particularly since they were now part of what was possibly turning out to be the greatest advance in the history of medicine. If your Alzheimer's had just been reversed at no charge, you weren't going to complain about a little hubbub on the roof.

"I'll wait here," Noda said opening the side door. His bald pate, reminiscent of an eighteenth‑century samurai, glistened in the early spring sun.

Bartlett nodded, knowing that his pilot did not trust physicians and hospitals. Taking care of your body was your responsibility, Kenji Noda frequently declared and he trained his own daily. He ate no meat and drank gallons of green tea. When he practiced kendo swordplay, he had the reflexes of a man half his age. He never discussed why he had left Japan, but Bartlett assumed it was for reasons best left in the dark.

Bartlett headed down the metal stairs leading to the self‑ service elevator. This daily ordeal of flying out to give a blood sample and to see Kristen was increasingly unsettling. As he inserted his magnetic card into the elevator security box, he felt his hand shaking slightly.

So close to the eternal dream of humankind. So close. How was it going to end?
