Pacing, she studied the symbols, tapping her fingers against the desktop with the music. She needed to understand why her predictions based on the control sample of Kramer’s Prometheus organism were so different from actual measurements out on the spill. The rate-of-reaction equations circled in red were orders of magnitude too small. The tiny organisms were supercharged somehow, like the coffee that kick-started her brain. But Iris couldn’t find the catalyst driving the little buggers. It worried her when she didn’t understand something.

The Prometheus problem had sunk its claws into her, grabbing her focus so that she noticed little else. She took another sip of coffee, not caring that it was lukewarm. Iris had long since lost count of how many cups she had downed that morning.

She leaned back against a black laboratory table and tried to make sense of what she knew. She thought she understood how Prometheus worked. Prometheus had an appetite for octane—eight carbons and ten hydrogens in a straight chain—metabolizing it into water and carbon dioxide. But no organism would eat only one food, and with the myriad components of crude oil, the microbes should be munching shorter-chain hydrocarbons and some of the aromatic ring molecules.

Since the spraying, multi-spectral imagery from high-flying NASA planes showed a marked decrease in oil density around the spill. Prometheus was metabolizing the spilled crude more than a hundred times faster than expected. TV and print journalists had begun running feature stories about Kramer’s “miracle.”

It pleased Oilstar to no end—but Prometheus wasn’t supposed to be behaving that way.

Iris had taken samples from the surface of the spill where it had been treated with Prometheus. She detected plenty of carbon dioxide as waste product, as expected, but she also found substantial traces of sulfur dioxide and sulfuric acid.

Alex Kramer and Mitchell Stone had delivered the original control sample of microbes only last week. Kramer claimed the sample had remained in a cryogenic container for over a year. “The microbes we’ll be spraying are identical, but one generation removed,” Stone had assured her.

After running simple tests on the control, Iris established microbe reaction rates, temporal densities, and localized activity, everything neatly pigeonholed in its own statistical universe. Routine stuff, but she took pride in her work. All of her predictions for Prometheus had been grounded on this baseline.

Were these latest anomalies happening because she had somehow goofed up her initial test run? A screwup causing this much variance could cause a genetic laboratory to lose its license, and Iris knew she wasn’t that sloppy. Her parents had imposed a rigorous work ethic and study regimen on her; Iris had hated it while growing up, but it had proved very useful once she got into Stanford. Now she was damned good at what she did, and she knew it. She had reviewed her work and found no errors—and so, logically, the problem must come from somewhere else.

The microbes Todd Severyn had sprayed on the oil spill just didn’t match the baseline. Nowhere close. The rates were all wrong. And that, in her opinion, was impossible.

Unless she had been given a fake control sample.

Her insides twisted with a rush of cold uneasiness, disbelief, and anger at being jerked around. Kramer did not seem the type to play practical jokes, nor did he seem so careless. She had read and admired some of his published papers on the Oilstar bioremediation work.

But a difference of this magnitude couldn’t possibly be a mistake.

The only way she could tell the two organisms apart was through a genetic check. It was tough enough tracking down minuscule differences in genetic structure without a devoted team and dedicated equipment. She had tried to use Schaeffer’s Autotrans 700 down the hall, but he had just upgraded his GeneWorks software and had not yet reconfigured the system. And she couldn’t pay for an outside service, either, since the state Environmental Policy and Inspection department had frozen its support of her work with Oilstar and a dozen regulatory agencies in the middle of their legal battles.

Besides, if Prometheus cleaned up the Zoroaster spill much faster than expected—that was terrific, wasn’t it?

Wasn’t it?

Iris drained the rest of her coffee and turned from the whiteboard to pour herself another cup. On the stereo, the lead singer for Kansas urged her to “Carry on.”

She’d been in her teens when the Exxon Valdez had slathered the Alaskan coast with crude oil. Since then, certain microbial strains had been researched for various bioremediation applications, from plastic in landfills to toxic waste. Wall Street had seen enormous potential in startup bioremediation firms; even the White House had established a major initiative in biotechnology.

As she reached the bottom of her next cup of coffee, Iris started to feel a tingling buzz as her system became saturated with caffeine. Good. It helped her think.

Todd Severyn would have told her not to worry about the reaction rates. It doesn’t matter if everything fits with predictions, as long as it works! She didn’t know whether to scowl in annoyance or be amused at his ridiculous posturing. She couldn’t decide what she disliked most, his defensive reaction to her or his straightforward naivete.

But Todd had surprised her by bulldogging his way to get the spraying job done, and by sticking to his word even to the point of being arrested. It was a far cry from the whitewashing and polite lies that permeated faculty politics here at Stanford.

Iris found herself staring at the whiteboard. Turning, she poured the remainder of her coffee down a chemical disposal. Time to make a new pot.

The expected anomalies—the so-called “known unknowns” such as bacterial infection—were a cinch to account for because they had some kind of logical explanation.

But Prometheus had too many “unknown unknowns.”

Chapter 21

For the first time since the spill, Jackson Harris woke from a sound sleep in his own bed, instead of a sleeping bag on Angel Island. He blinked bleary eyes at the glowing green numbers on his digital clock on the nightstand next to his glass of water.

Daphne shook him awake again. “You’re gonna miss your interview, Jackson!” She was already up and dressed. He never understood how he could have been crazy enough to marry a genuine morning person.

Jackson and Daphne Harris had returned from Angel Island to their house in Oakland to prepare for several media interviews about their volunteer work. His stunt with the oil-covered pelican at Oilstar’s town meeting had been melodramatic, calculatedly so, but man did it make for great television! And there had been plenty of cameras to record it. No way did he mind media attention, not if it served the cause.

In an hour, he was scheduled to be interviewed in the San Francisco National Public Radio studio for their morning “Forum” show; then he would go to the KRON TV studio to tape a human-interest spot for the evening news on Channel 4. TV stations liked Harris because he was actually doing something about his convictions, getting volunteers to work, putting his money where his mouth was. And these interviews worked like magic, stirring up donations to keep the brothers and sisters going.

As he crawled out of bed, Harris smelled coffee brewing, a rich aroma that smelled good enough to waft off a commercial. He listened to the morning city sounds of Oakland: the traffic, the neighbors, the radio sounded too loud after days isolated on the island. He flinched with guilt, knowing his volunteers had to make do with the primitive facilities available on the state park.
