Langdon had chased Sienna off into the night, and Sinskey had still not received word regarding what had happened to either of them.
I hope Professor Langdon is safe, she thought.
Agent Brüder stood dripping on the boardwalk, staring blankly out at the inverted head of Medusa and wondering how to proceed.
As an SRS agent, Brüder had been trained to think on the macrocosmic level, setting aside any immediate ethical or personal concerns and focusing on saving as many lives as possible over the long term. Threats to his own health had barely registered on him until this moment. I waded into this stuff, he thought, chastising himself for the risky action he had taken and yet knowing he’d had little choice. We needed an immediate assessment.
Brüder forced his thoughts to the task at hand — implement Plan B. Unfortunately, in a containment crisis, Plan B was always the same: widen the radius.Fighting communicable disease was often like fighting a forest fire: sometimes you had to drop back and surrender a battle in hopes of winning the war.
At this point, Brüder had still not given up the idea that a full containment was possible. Most likely Sienna Brooks had ruptured the bag only minutes before the mass hysteria and evacuation. If that were true, even though hundreds of people had fled the scene, everyone might have been located far enough away from the source to avoid contamination.
Everyone except Langdon and Sienna, Brüder realized. Both of whom were here at ground zero, and are now someplace out in the city.
Brüder had another concern as well — a gap in logic that continued to nag at him. While in the water, he had never found the actual breached Solublon bag. It seemed to Brüder that if Sienna had broken the bag — by kicking it or ripping it or whatever she had done — he would have found the damaged, deflated remnants floating somewhere in the area.
But Brüder had found nothing. Any remains of the bag seemed to have vanished. Brüder strongly doubted that Sienna would have carried off the Solublon bag with her, since by this point it would have been no more than a slimy, dissolving mess.
So where did it go?
Brüder had an uneasy sense that he was missing something. Even so, he focused on a new containment strategy, which required him to answer one critical question.
What is the contagion’s current dispersal radius?
Brüder knew the question would be answered in a matter of minutes. His team had set up a series of portable virus-detection devices along the boardwalks at increasing distances from the lagoon. These devices — known as PCR units — used what was called a polymerase chain reaction to detect the presence of viral contamination.
The SRS agent remained hopeful. With no movement of the water in the lagoon, and the passage of very little time, he was confident that the PCR devices would detect a relatively small region of contamination, which they could then attack with chemicals and the use of suction.
“Ready?” a technician called out through a megaphone.
Agents stationed around the cistern gave the thumbs-up.
“Run your samples,” the megaphone crackled.
Throughout the cavern, analysts crouched down and started their individual PCR machines. Each device began analyzing a sample from the point at which its operator was located on the boardwalk, spaced in ever-widening arcs around Zobrist’s plaque.
A hush fell across the cistern as everyone waited, praying to see only green lights.
And then it happened.
On the machine closest to Brüder, a virus-detection light began flashing red. His muscles tensed, and his eyes shifted to the next machine.
It, too, began blinking red.
No.
Stunned murmurs reverberated throughout the cavern. Brüder watched in horror as, one by one, every PCR device began blinking red, all the way across the cistern to the entrance.
Oh, God …he thought. The sea of blinking red detection lights painted an unmistakable picture.
The radius of contamination was enormous.
The entire cistern was teeming with virus.
CHAPTER 97
Robert Langdon stared down at Sienna Brooks, huddled at the wheel of the stolen powerboat, and struggled to make sense of what he had just witnessed.
“I’m sure you despise me,” she sobbed, looking up at him through tearful eyes.
“Despise you?!” Langdon exclaimed. “I don’t have the slightest idea whoyou are! All you’ve done is lie to me!”
“I know,” she said softly. “I’m sorry. I’ve been trying to do the right thing.”
“By releasing a plague?”
“No, Robert, you don’t understand.”
“I dounderstand!” Langdon replied. “I understand you waded out into the water to break that Solublon bag! You wanted to release Zobrist’s virus before anyone could contain it!”
“Solublon bag?” Sienna’s eyes flashed confusion. “I don’t know what you’re talking about. Robert, I went to the cistern to stopBertrand’s virus … to stealit and make it disappear forever … so nobody could ever study it, including Dr. Sinskey and the WHO.”
“Steal it? Why keep it from the WHO?”
Sienna took a long breath. “There’s so much you don’t know, but it’s all moot now. We arrived much too late, Robert. We never had a chance.”
“Of course we had a chance! The virus was not going to be released until tomorrow! That’s the date Zobrist chose, and if you hadn’t gone into the water—”
“Robert, I didn’trelease the virus!” Sienna yelled. “When I went into the water, I was trying to find it, but it was too late. There was nothing there.”
“I don’t believe you,” Langdon said.
“I know you don’t. And I don’t blame you.” She reached into her pocket and pulled out a soggy pamphlet. “But maybe this will help.” She tossed the paper to Langdon. “I found this just before I waded into the lagoon.”
He caught it and opened it up. It was a concert program for the cistern’s seven performances of the Dante Symphony.
“Look at the dates,” she said.
Langdon read the dates and then reread them, puzzled by what he saw. For some reason, he had been under the impression that this evening’s performance was opening night — the first of seven performances to be given during the week, designed to lure people into a plague-infested cistern. This program, however, told a different story.
“Tonight was closingnight?” Langdon asked, glancing up from the paper. “The orchestra has been playing all week?”
Sienna nodded. “I was as surprised as you are.” She paused, her eyes somber. “The virus is already out, Robert. It hasbeen for a week.”
“That can’t be true,” Langdon argued. “ Tomorrowis the date. Zobrist even made a plaque with tomorrow’s date on it.”
“Yes, I saw the plaque in the water.”
“Then you know he was fixated on tomorrow.”
Sienna sighed. “Robert, I knew Bertrand well, better than I ever admitted to you. He was a scientist, a results-oriented person. I now realize that the date on the plaque is not the virus’s releasedate. It’s something else, something more important to his goal.”
“And that would be …?”
Sienna gazed up solemnly from the boat. “It’s a global-saturation date — a mathematical projection of the date after which his virus will have propagated across the world … and infected every individual.”
The prospect sent a visceral tremor through Langdon, and yet he couldn’t help but suspect that she was lying. Her story contained a fatal flaw, and Sienna Brooks had already proven she’d lie about anything.
“One problem, Sienna,” he said, staring down at her. “If this plague has already spread all over the world, then why aren’t people getting sick?”
