The Cobra Event (24 page)

Austen found Lesdiu sitting at a table in the center of the materials room, the cobra boxes before him under bright lights. He was holding an old-fashioned magnifying glass in one hand and a pair of tweezers in the other. His hands were enormous. They were covered with double rubber gloves.

“I’m dying inside this suit,” he confessed to Austen. He was dressed in an extra-large F.B.I. biohazard suit, and he looked extremely uncomfortable. His Racal hood was beaded with sweat on the inside. He had draped a towel over his shoulder—inside his hood. Now he shifted his shoulder, turned his head, and wiped the sweat off his face using the towel.

Lesdiu probed the tweezers here and there in one of the boxes.

“I’m looking for hair-and-fiber evidence,” he explained. Lesdiu plucked at something inside the box. “There’s another hair. It’s another Q.”

Austen had never heard the term
Q
.

Lesdiu explained that he had found some unknown human hairs. “They’re questioned hairs,” he said. “We call unknown samples Q evidence, or questioned evidence. It’s questioned because you don’t know what it is or where it comes from.” He had placed the hairs on a sheet of brown paper. “Samples are either questioned samples or known samples. The questioned samples are things that are found at the crime scene. Sherlock Holmes called them clues.” He smiled. “Qs are physical evidence. We analyze the Q samples, hoping to match them with something known. Forensic science is largely pattern recognition. The Qs are things like fingerprints, hair and fibers, blood, toolmarks, shoe prints, all kinds of trace evidence. DNA is trace evidence. The DNA of the Cobra virus that you’ve been looking at on the screens, that’s a questioned sample, because we don’t know where the Cobra virus comes from.”

Austen realized that this was very similar to what she had been doing in the beginning, when she had traced the outbreak to the boxes. “You guys are doing a diagnosis of a crime.”

“In a way, yeah,” Lesdiu said.

The F.B.I. maintains enormous reference collections of known samples of all kinds of objects. These are called reference knowns. “If you can match a fingerprint, you can get a conviction,” Lesdiu said. “Because a fingerprint pattern is unique. But forensic evidence is not always so clear. That’s why you usually need a lot of it.”

Lesdiu put his tweezers down. He was taking a break. “I’ve got two hairs so far,” he said. They come from the Zecker-Moran box. One is a fine, reddish hair, with an oval shaft, Caucasian.”

“That sounds like Kate’s hair,” Austen said.

“It probably is,” Lesdiu said. “Frank Masaccio’s folks are getting some known hair samples from her bedroom. As soon as they arrive, I can start comparing Qs and Ks. The other hair is oval and transparent. It’s a gray hair from a Caucasian.”

“Penny Zecker,” Austen said.

“Maybe. We’ll be getting hair samples from her house too. I also found some wool fibers. Black. Maybe from a sweater—maybe the girl’s sweater, maybe not. The other box, the one the homeless guy carried around with him—” Lesdiu indicated the Harmonica Man box, which was sitting beside the Zecker-Moran box. “This one has a ton of fibers all over it and in the cracks. The fibers are cotton and polyester. The box was wrapped up in the guy’s clothes. I have to say that anyone who was smart enough to load this box with a virus is smart enough not to leave any hair or fibers on it. This fiber analysis is not going to pan out. My bones are telling me that. But there’s more than one way to skin a cat. There’s a ton of microscopic evidence in these boxes.”

JIMMY LESDIU
had set up a row of machines in the materials room. One of them could throw a beam of infrared laser light on an object and then analyze the spectrum of the light bouncing off the object. The machine gave information about what the sample was made of. It could also see invisible fingerprints on a surface. Lesdiu had also set up a machine that could vaporize a sample and identify the atoms in the gas coming out of the sample.

Lesdiu found a number of fingerprints on the boxes. He photographed them in laser light and sent the images by satellite to Washington, where the fingerprints would be analyzed. Later, it would turn out that none of the fingerprints belonged to the Unsub. They belonged to Kate Moran and Penny Zecker. The Unsub had been much too careful to leave fingerprints.

A shiny black enamel had been used to paint the design on the box. With the infrared laser, Lesdiu got a spectrum of colors from the paint. To the human eye, the paint was black, but to the laser it was a rainbow of colors. Lesdiu passed the paint spectrum on to Washington, and within minutes an F.B.I. expert in paint called him back on the telephone. The call came into the hot Core on a speakerphone, since you can’t use a telephone handset if you are wearing a Racal hood.

“You folks in Forensics must be standing around waiting for me to call,” Lesdiu shouted on the speakerphone to his paint expert.

“We’ve been told to respond quickly. Frank Masaccio will kill us if we don’t.” The paint expert went on to say that the paint was a common enamel model paint. It was sold in hobby shops everywhere.

The signature had petered out into a maze of common objects. This was typical of signatures. Still, the paint was a Q that could be tied to a K, if a suspect turned up with enamel model paint.

The cobra boxes had bits of paper glued to them, on which words were written—Archimedes’ name and the date. The bits of paper were glued to the box with a clear, flexible glue. With a razor blade, Lesdiu cut away a tiny shred of the glue. “It’s kind of a rubbery glue,” he said. “I’d say it’s a silicone glue or a hot-melt type of glue.”

He dropped a bit of the glue from the knife onto a glass slide, ran it through the laser machine, and got some data. “I got a real nice infrared spectrum of this glue. Look at that, isn’t that
beautiful
?” he said.

Alice Austen stared at the screen. It was a meaningless jagged line to her. She told Jimmy Lesdiu as much.

“There’s information in these peaks and valleys,” he said.

“If you looked at a cell, you wouldn’t see much in it,” she said to him. “I would see a world.”

There was a man at F.B.I. headquarters who could see a world in a drop of glue. They called him the Maven of Glue. James Lesdiu sent the spectrum of the glue over an encrypted satellite link to the F.B.I. forensic lab at headquarters in Washington, meanwhile talking on his speakerphone to the scientist known as the Maven of Glue. The Maven put Lesdiu on hold for a few minutes, and then said to him, “Okay, Jimmy, I’ve checked the spectrum against our library of adhesives. You are not going to be happy, Jimmy.”

“I’m listening,” Lesdiu said, standing by the speakerphone.

“The spectrum you sent is consistent with a silicone glue made by the Forkin Chemical Company in Torrance, California. It’s called Dabber Glue. They sell millions of tubes of this stuff. You can buy it in any hardware store. I really like it. It’s a nifty glue. I use it myself at home.”

Austen said, “Why doesn’t somebody call Forkin Chemical?”

Lesdiu shrugged. “That would probably be useless. They can’t trace millions of tubes.” Nevertheless, he called Frank Masaccio with the information, and an F.B.I. agent got in touch with the president of Forkin Chemical. The agent and the company president had a very pleasant conversation, and the president called an emergency meeting of his technical people and his top sales staff for the northeastern United States. But in the end, there was nothing the management of the company could do to help narrow down the retail source of the glue. The company said that there were at least three hundred retail-outlet stores in the New York area that would be selling Dabber Glue. And of course the Unsub might not have bought the glue in the northeastern United States. The glue was sold everywhere.

Lesdiu held the box in his long fingers, squinting at it. He looked at it with his Sherlock Holmes hand-magnifying lens. He found some kind of black, powdery dirt embedded in the glue. Very fine particles of dirt, jet black.

“
I’m going to nail this dirt
,” Jimmy Lesdiu said.

He had to separate a few particles of dirt from the glue, and silicone does not dissolve in most solvents. But after a further conversation with the Maven of Glue and with chemists at headquarters, Lesdiu came up with a solvent that would work. He rooted in one of the supply boxes, shuffling through bottles, until he found what he was looking for. Then he dissolved a bit of the glue in a small test tube, and swirled the particles. A blackish, brownish haze hung in the liquid. Now he had to separate the particles. He returned to a supply box and found a magnet He held the magnet against the test tube. The black dust drifted toward the magnet. “It’s a ferromagnetic material. It’s iron or steel,” he said. But the brown haze did not move under the magnet. The brown haze was probably an organic material or rock or concrete dust. Lesdiu had separated the dirt into two components—a black dust and a brown haze.

“I’ve done an autopsy on a terror device,” Lesdiu remarked to Austen.

But now he had reached the end of what was possible with a Reachdeep portable operation. The sample of dust had to go to the F.B.I. metallurgists in Washington, who would continue the analysis. Into the test tube of dusts he dropped a strong disinfectant—to sterilize the contents, just in case it contained any live Cobra virus particles. A few minutes later, a Bell turbo helicopter took off for Washington bearing the test tube. The team would have to wait several hours, at least, before the F.B.I. metallurgists could tell what the black dust was. The particles might contain information, but whether that information would constitute a signature that could lead back to the perpetrator, no one knew.

The only part of the boxes not yet studied was the wooden material of the box itself. James Lesdiu pondered it. He didn’t recognize the type of wood. He didn’t recognize the design and style of the box, either. It was clearly handmade, and Lesdiu guessed that either Archimedes had made the box himself or that he had bought it at a trinket shop. Reachdeep needed a forensic botanist. Lesdiu called Washington and asked that an expert on wood be flown to Governors Island. Then he photographed the boxes in different kinds of light. He was especially interested in the small pieces of paper that were glued to the boxes. He set up a camera stand and photographed the papers with different kinds of light shining on them. It seemed that the Unsub had been careful to avoid watermarks when cutting the paper. The text itself was from a high-resolution laser printer. The type font was Courier, a common font. While F.B.I. scientists could identify characters from an old-fashioned typewriter, they could not identify laser-printer output. The chemical composition of the paper might lead to a particular manufacturer, but that would probably not be helpful in finding the Unsub.

Every detail of the boxes had been chosen by the Unsub to be hard to trace.

WILL HOPKINS HAD SET UP
a series of videoconference meetings with molecular biologists at the Centers for Disease Control and at U
SAMRIID
at Fort Detrick. The experts told him that the Cobra chimera had been built on the most common laboratory strain of baculovirus. It was available through the mail, and it was in use everywhere in the world. The experts told him that they did not know how the virus could be made to replicate explosively in human cells. One of them said to him, “It’s doable. But I just don’t know how. The baculovirus is adaptable, and someone’s figured out how to adapt it to humans, that’s all.”

Mark Littleberry studied James Lesdiu’s magnified photographs of the bits of paper glued to the boxes. He was interested in the drawing of a bioreactor that appeared on Harmonica Man’s box. He had never seen this exact type of bioreactor before, but in studying the drawing he became convinced that it had been done from life. The drawing had been made by Archimedes using a simple drawing program on a computer, and then it had been shrunk to a tiny size on a laser printer. The drawing was sketchy, but Littleberry believed it had been done by someone who had used a bioreactor and knew exactly how it worked. But who had manufactured the bioreactor? Littleberry and various F.B.I. agents with Masaccio’s task force studied sales catalogs and made telephone calls asking about the designs of bioreactors made by companies in the United States. It was not an American design. Littleberry came to suspect—it was a gut feeling, but he couldn’t prove it—that the bioreactor came from either an Asian biotechnology company or from perhaps Russia. Tracing it would be very difficult.

The forensic Reachdeep operation was not going as well as Hopkins had hoped. The idea that so many lives might depend on his team’s work frightened him. At times he wished he had never joined the F.B.I. Even though he was dog-tired, he found that he couldn’t sleep, and he wondered if he was getting an ulcer.

During a discussion of the Unsub’s motives, Hopkins suddenly hurried out of the meeting room, and people heard him throwing up in the bathroom. He came out after a while looking shaky. He said that he had been drinking too much coffee. Some of them were afraid he might be getting sick with the virus, but they didn’t know what to say or do about it.

“I’m scared for Will,” Littleberry later remarked to Austen. “I’m wondering if he made promises he can’t keep.”

Chimera

HOPKINS WAS THINKING ABOUT
the virus that he and Littleberry had found in Iraq. The drawing of the bioreactor on the cobra box looked somewhat like the bioreactor that he had seen inside the truck in Iraq—at least from what he could remember. The possibility that the deaths in New York were a terrorist event being sponsored by Iraq weighed on him. He discussed it by phone with Frank Masaccio. Masaccio was very disturbed by this. “If this is terrorism sponsored by a foreign government, Will, this could start a war.”

“I know, Frank,” Hopkins said.

Hopkins put in a call to the Navy’s Biological Defense Research Program in Bethesda, where one of his contacts, a Navy doctor named John Letersky, was working through the night. Letersky was a member of the group that supplied Felix equipment to the F.B.I. He had been trying to analyze the chunks of genetic material that Hopkins and Littleberry had beamed up to the satellite when they’d been locked in the rest room.
