"Wake up, David," she said softly in his ear. "For God's sake, wake up."

WHITE SANDS

Ravi Nara parked his ATV outside the hospital hangar and walked to the door. In his pocket was a syringe of potassium chloride that would stop Godin's weakened heart as surely as a bullet.

He paused at the hangar door, unable to open it. It had taken hours to steel himself for this visit, and with¬out Skow threatening him, he would not have made it this far. They're watching this on monitors somewhere, he said to himself. Move.

He entered the hangar, slipped on a fresh lab coat, then walked into the decontaminator and stepped on the floor switch. High-intensity UV light bombarded him from all sides. As he stood in the purple glow, he stared through the hatch in the Bubble. Godin's nurses sat like guard dogs on either side of the bed. It's him or me, he told himself. Remember what Skow said…

The NSA man had not shouted with joy when he'd learned that the computer might reach Trinity state within twelve hours. He'd asked how long Godin was likely to live. When Ravi answered more than twelve hours, Skow told him that could not be allowed to happen.

"Why not?" Ravi had asked, afraid he already knew the answer.

"Because it's too late," Skow snapped. "The president called me from China, very upset about the Tennant situ¬ation. Very suspicious, too. I had to tell him something that made sense."

"Something besides the truth, you mean."

"Exactly. I told him that Peter has been ill all along, and that I was afraid he might be responsible for Fielding's death. I told him that Peter had disappeared, and that there might be a secret research facility some¬where. The FBI is tearing apart the Godin Supercomputing complex in Mountain View as we speak."

Ravi shut his eyes and prayed this was a nightmare. In the conference room in North Carolina, the decision to end Fielding's life had seemed almost an official gov¬ernment act. Trinity existed to strengthen America 's strategic position in the world. Fielding had sabotaged its progress. But when you stripped away the window dressing, Fielding's "termination" had been plain old murder.

" Ravi?"

"I'm here." He knew what Skow was going to ask of him. And he dreaded it.

"You know what has to be done."

Ravi made one last stand. "You said that if we deliv¬ered Trinity, no one would care who had died to make it happen."

"That was before the mess with Tennant. We've had a shooting in Washington, for God's sake. I've painted Tennant as a dangerous psychotic, but that's all right. I have medical evidence to support that." "Those are problems for you, not me." Skow spoke calmly, but his words chilled Ravi 's blood. "You're not the only person who knows you were part of Fielding's death. I have recordings of you. Very incriminating recordings. We're all in the same boat, Ravi. You, me, Geli, and General Bauer. If we all tell the same story, no one can touch us. But Peter has to die." Ravi closed his eyes in anguish.

"Our lives are in your hands, Ravi. A few seconds of courage will wash you clean."

Clean! he thought. I'll never be clean again. Was it morally wrong to kill Godin? The man was only hours from a natural death, and without Ravi he would have died days ago. Godin had ordered the mur¬der of Andrew Fielding without any visible compunc¬tion. And beyond that, there was the almost fantastic reality that killing Godin's biological body would not really end his life. As long as his neuromodel existed, his mind and personality could be resurrected in the Trinity computer.

The problem was not one of morality, but of opportu¬nity. When a man was as sick as Godin, there were a half dozen ways to push him over the edge. But Godin's nurses never left him alone. Ravi had tested them twice today; in both instances they had taken cell phones from their pockets and awakened sleeping relief nurses for assistance.

After considering several options, Ravi had prepared the syringe of potassium chloride. As a diversion, he would trigger an alarm on one of the monitors, then inject the potassium into Godin's IV line. A code blue would follow-one that Godin would never survive.

The UV lights of the decontaminator buzzed and went dark. Ravi saw the blur of nurse's whites through the Bubble's Plexiglas door.

Where the hell is Geli Bauer? he thought. This job is tailor-made for her.

Ravi opened the Bubble's hatch and stopped, his throat sealed shut. Standing beside one of Godin's nurses was Geli Bauer. She wore black from head to toe, and she looked every bit as dangerous as she had when he had last seen her in North Carolina.

"Hello, Ravi," she said. "You look surprised to see me."

Ravi could not speak. Geli wore an armored vest over her black bodysuit, and a web belt laden with pistol, Taser, and knife.

Godin raised the upper half of his bed with a switch, his blue eyes locked on Ravi. Only then did Ravi realize that Godin had been taken off the ventilator.

"What do you have to say, Ravi?" the old man asked.

"I'm surprised to see Geli up and around," he stam¬mered. "I'd heard it was a neck wound."

Geli smiled, then pulled down her black turtleneck, revealing a white pressure bandage. "Just another scar to add to my collection. I had a good surgical team."

Ravi 's heart thumped against his sternum. What the hell was Geli doing in White Sands? And why was she guarding Godin? According to Skow, she'd accepted the necessity of Godin's death and was on board with Skow's plan.

The old man seemed amused by Ravi 's discomfort. "Well, here I am, back from the dead," he rasped. "They tell me it was my heart this time."

"Ventricular tachycardia," Ravi confirmed.

"I hear it was my nurses who brought me back."

All Ravi could think about was the syringe in his pocket. He felt sure that Geli was going to walk over to him, pull out the syringe, and jam it into his jugular vein. "They did everything perfectly," Ravi said. Godin nodded. "Would you have done the same, Ravi? If you were alone with me?"

Ravi 's stomach flipped over. "I don't understand, Peter. Of course I would have."

Godin ignored his answer. "As for Geli… I wanted her with me. I feel safer when she's around."

The piercing blue eyes fixed Ravi with a relentless stare. "What are you doing here. Dr. Nara?"

"I was hoping to take you off the ventilator. But I see your nurses have already done that."

Godin glanced at Geli. They seemed to be sharing a private joke.

Ravi searched for something to support his lie. "Levin told me the prototype could reach Trinity state soon. I knew you'd want to be as alert as possible when that happens."

"And all due to Andrew Fielding," Godin said. "The ironies are breathtaking."

Ravi glanced nervously at Geli. "It's a miracle, Peter. You're going to live to see your dream come true."

Godin's lids descended until his eyes were slits. "Really? Have you heard from Skow lately?"

Ravi 's blood pressure plummeted. "I spoke to him earlier today. He's very excited. He's going to fly out soon."

Godin snorted. "He wants to be present at the cre¬ation?"

"I suppose so. I mean, naturally he does." The ensuing silence became almost unbearable. Ravi couldn't bring himself to look into Geli's eyes. He was searching for an excuse to leave when Godin said, "How long do I have left? Worst case?"

Ravi was too frightened to speak anything but the truth. "You could code again in the next half hour. If you chew your food wrong, it could trigger fatal hydrocephalus."

Godin nodded soberly. "What's the longest I could live?"

"Maybe… twenty-four hours."

Ravi marshaled all his courage and stepped toward the bed. "I'd like to do a quick examination, if you don't mind."
