was scouring the country for her, and Richards, that lunatic, had left a trail of bodies a mile wide. The nuns at the convent, shot in their sleep. A pair of small-town cops. Six people at a coffee shop whose only mistake was coming in for breakfast at the same time as Wolgast and the girl.
But the request for the girl, which had come from Lear himself, was nothing Guilder could make himself refuse. Each of the cons had been infected with a slightly altered variant of the virus, though the effects had been the same. Illness, coma, transformation, and the next thing you knew they were hanging upside down from the ceiling, gutting a rabbit. But the Amy variant was different. It hadn’t come from Fanning, the Columbia biochemist who’d been infected on Lear’s misbegotten excursion to Bolivia; it had come from the group of tourists who’d started the whole thing—terminal cancer patients on a lark in the jungle with an ecotour group called Last Wish. They’d all died within a month: stroke, heart attack, aneurysm, their bodies blowing apart. But in the meantime, they’d shown remarkable improvements in their condition—one man had even grown back a full head of hair—and they’d all died cancer-free. Reading Lear’s mind was a fool’s errand, but he’d come to believe this variant was the answer. The trick was keeping the first test subject alive. For this he’d chosen Amy, a young, healthy girl.
And it had worked. Guilder knew it had worked. Because Amy was still alive.
Guilder’s office, on the third floor of an otherwise nondescript low-rise federal office building in Fairfax County—DSW shared space with, among other entities, the Office of Technology Assessment, the Department of Homeland Security Special Energy Task Force, the National Oceanic and Atmospheric Administration, and a day care—looked out on Interstate 66. Monday of Memorial Day weekend, yet there was almost no traffic. A lot of people had left the city already. Guilder imagined a lot of chits were being called in. A mother-in-law in upstate New York. A friend with a cabin in the mountains. But with all air transportation grounded, people could get only so far, and it wouldn’t make much difference in the end. You couldn’t hide from nature forever. Or so Horace Guilder had been told.
The girl had made it out of Colorado somehow. They’d caught her signature in southern Wyoming in the first few hours. Which meant she was in a vehicle, and not alone—somebody had to be driving. After that, she’d disappeared. The transmitter in her biomonitor was short-range, too weak for the satellites; she had to be within a few miles of a cell tower, and not some rural co-op but one connected to the federal tracking network. Which, in southern Wyoming, as long as you stayed off major highways, would be easy to avoid. She could be anywhere now. Whoever was with her was smart.
A knock at the door broke his train of thought; Guilder swiveled from the window to see Nelson, the department’s chief technical officer, standing in the doorway. Christ, what now?
“I have good news and bad news,” Nelson announced.
Nelson was dressed, as always, in a black T-shirt and jeans, his dirty feet shoved into a pair of flip-flops. A fast-talking Rhodes scholar with not one but two PhDs from MIT—biochemistry and advanced information systems—Nelson was the smartest guy in the building by a mile, a fact that he knew only too well. He still had the young person’s predisposition to regard the world as a series of vaguely irritating problems created by people less cool and smart than he was. Though their relationship was cordial, Nelson had a habit of treating Guilder like a doddering elderly parent, a figure of respect but no longer quite worthy—which was exasperating, coming from a guy who seemed to comb his hair every fourth day, though not, Guilder had to admit, entirely unwarranted. He was twenty-eight to Guilder’s fifty-seven, and everything about Nelson conspired to make him feel old.
“Any sign of her?”
“Nada.” Nelson scratched his scraggly beard. “We’re not getting any of them.”
Guilder rubbed his eyes, which stung of sleeplessness. He needed to go home for a shower and a clean suit. He hadn’t left the office in two days, grabbing only a few winks on the couch and living on junk from the vending machines. He was having trouble with his fingers, too. Numbness, tingling.
“You said something about good news?”
“Depends on how you look at it. From a free-speech point
