Wright’s left eyelid began to twitch. “That’s quite impossible. Our entire marketing campaign would be derailed. The publicity would be devastating.”

“We shall see,” Pendergast replied. “Now, unless there’s anything else, I don’t think we need keep you any longer.”

Wright, his face drained of color, stood up and, without a word, walked stiffly out of the room.

[100] “What’s that again, Lieutenant?” Pendergast asked, leaning back in the leather chair and picking up the book with renewed enthusiasm.

“Come on, Pendergast,” D’Agosta said, looking cagily at the FBI agent. “I guess you can drop the genteel act when it suits you.”

The laboratory looked out over the East River and across to the warehouses and decaying industrial buildings of Long Island City. Lewis Turow stood in the window and watched an enormous barge, piled with garbage and surrounded by countless seagulls, being pushed out to sea. Probably one minute’s worth of New York City garbage, he thought.

Turow turned away from the window and sighed. He hated New York, but one had to make choices. The choice for him was enduring the city and working in one of the best genetic labs in the country, or working in some halfassed facility in a nice rural spot somewhere. So far he’d chosen the city, but his patience was ru

He heard a low beeping, then the soft hiss of a miniprinter. The results were coming through. Another soft beep indicated the print job was finished. The threemillion-dollar Omega-9 Parallel Processing Computer, which took up a series of large gray boxes along one wall, was now completely silent. Only a few lights [102] indicated that anything was happening. It was a special, hardwired model designed for sequencing DNA and mapping genes. Turow had come to the lab six months before specifically because of this machine.

He fetched the paper out of the bin and sca

The target group, in this case, was unusual: big cats. They had asked for gene matches with Asiatic tiger, jaguar, leopard, bobcat. Turow had thrown in the cheetah, since its genetics were so well known. The outgroup chosen was, as usual, Homo sapiens, a control to check that the genetic matching process had been accurate and the sample sound.

SAMPLE: NYC Crime Lab LA-33

SUMMARY

 

TARGET GROUP

 

                                                % matches            degree of confidence

Panthera leo                         5.5                           4%

Panthera onca                      7.1                           5%

Felis lynx                              4.0                           3%

Felis rufa                               5.2                           4%

Acinonyx jubatus                6.6                           4%

 

OUTGROUP CONTROL

 

Homo sapiens                      45.2                         33%

 

Well, this is complete bullshit, thought Turow. The sample matched the outgroup a lot more than it matched the target group—the opposite of what should have [103] happened. Only a 4 percent chance that the genetic material was from a big cat, but a 33 percent chance it was from a human being.

Thirty-three percent. Still low, but within the realm of possibility.

So that meant trying GenLab for a match. GenLab was an enormous international DNA database—two hundred gigs and growing—that contained DNA sequences, primers, and mapped genes for thousands of organisms, from the Escherichia coli bacterium to Homo sapiens. He would run the data against the GenLab database, and see just what this DNA was from. Something close to Homo sapiens, it looked like. Not high enough to be an ape, but maybe something like a lemur.

Turow’s curiosity was piqued. Till now, he didn’t even know that his laboratory did work for the police department. What the hell made them think this sample came from a big cat? he wondered.

The results ran to a hefty eighty pages. The DNA sequencer printed out the identified nucleotides in columnar format, indicating species, identified genes, and unidentified sequences. Turow knew that most of the sequences would be unidentified, since the only organism with a complete genetic map was E. coli.

[104] Turow glanced over the figures, then carried the paper over to his desk. With a few keystrokes on his SPARC-station 10, Turow could access information from thousands of databases. If the Omega-9 did not have the information he sought, it would automatically dial into the Internet and find a computer that did.
