“And how do you tell whether the purple stain Calvin’s got here is a friendly species or a deadly strain?”
“The most precise way is a DNA analysis,” he answered, “but that takes time. So I had Calvin do a two-stage stain. Calvin, could you show Dr. Brockton the next slide?” Calvin obliged, bringing up a slide showing small specks of red and black. “This second stain tells us that the bacteria in Lowe are from the genusClostridium. ”
“Go on,” I prompted.
“Clostridiumis an interesting study in contrasts,” he said. “There are about a hundred species of it. Some of them are very useful—they have the potential to convert wood into ethanol or to target therapeutic drugs at cancer tumors.”
“So the good news is biofuels and magic bullets,” I said. “What’s the bad news?”
“Food poisoning. Tetanus. Botulism. Gas gangrene. Toxic shock.Clostridium produces some of the deadliest toxins on the planet. One thing about it that’s interesting,” he added, “is that we’re exposed to these bacteria all the time.Clostridium lives mostly in the soil, in dirt and rotting organic material—there’s probably a lot of it out at the Body Farm—but we also carry some species of it in our gastrointestinal tract. The vast majority of the time, our bodies manage to keep it in check.”
“So something tipped the scales in Lowe’s body after surgery,” I said, “allowing the bacteria in her gut to multiply like crazy and spread throughout her body?”
“Actually, no,” he answered. “I don’t believe her GI tract was the source. Remember, these slides you’re seeing are tissue samples from the allograft in her cervical spine. I think she received a graft of contaminated cadaver bone.”
I stared at the images on the microscope monitor. If Garcia was right, the surgeon had unwittingly put a ticking bacteriological time bomb into his patient. And that bomb was sitting on a countertop a few doors down the hallway. And I’d been handling it casually—gloved, but not masked—for the past hour. “What should I do with the cervical spine? Should I boil it? Sterilize it in an autoclave? Incinerate it?”
“I’d like to do more testing on it. Maybe contact the company that supplied it. I checked the operating notes, but there’s nothing that indicates who made it. I’ll call the surgeon and find out. Meanwhile, would you bag it and freeze it?”
“Sure.”
“And, Bill? Be sure to cover it with biohazard labels.”
For once in the conversation, I was already way ahead of him.
TWO HOURS AND HALF Adozen hand washings later, Special Agent Ben Rankin phoned me.
“Hello, Rooster,” I said. “Are we still on for our meeting tomorrow morning?” We were scheduled to talk with Amanda Whiting, UT’s general counsel, about the proposed sting operation.
“No. We need to reschedule it.”
I was disappointed to hear that. We’d scheduled the meeting at eight at the FBI’s main office, located downtown in the John Duncan Federal Building. The part I’d been looking forward to wasn’t the meeting itself but the breakfast we’d decided to grab beforehand at Pete’s, a downtown coffee shop just around the corner.
“You need to be someplace else in the morning?”
“I do. So do you.”
“Me?” I checked my pocket calendar. According to it, my morning was open, except for the FBI meeting. “Where do I need to be in the morning?”
“Las Vegas. And actually, you need to be there tonight. Your flight leaves in two hours.”
CHAPTER 22
I AWOKE TO THE THUNK OF THE 737’S LANDING GEARcycling down on approach to the Las Vegas airport. As the plane banked in the night sky, the city glittered and flashed like the world’s biggest carnival, full of dazzling promises, dizzying rides, and rigged games of skill and chance. The trip itself was a high-stakes gamble, I reflected as the plane eased down to the runway. Las Vegas was not my dream destination; I’d far rather have been headed two hundred miles to the east, to the stark, rugged landscape of the Grand Canyon. But Vegas, not the Grand Canyon, was hosting the annual meeting of the National Consortium of Tissue Banks. At Rankin’s last-minute request just ten hours earlier, I’d filled out the online registration form, dashed home to pack a bag, and then raced to catch a hastily arranged flight.
As the jet angled off the runway and onto a taxiway, I switched on my cell phone, which beeped to tell me I had a new voice mail. “Call me,” said Rankin’s voice. I didn’t call him back until after I’d caught the monorail to the main terminal—even the airport had the feel of a theme park—and hailed a cab for the hotel. Rankin picked up on the second ring. “Hey, how was the flight?”
