“That’s what I’m getting around to,” Berger said. “This idea of the microchip implant. When you talked to Oscar, did you get any idea that might lead you to believe he’d ever, for any reason, allow something like that? Lucy and I are watching this God-awful video again, and that’s what the killer is implying. Morales, I mean. We know it’s him.”

“Oscar would never allow that,” Scarpetta said. “What’s far more likely is he complained about painful treatments, specifically, laser hair removal. And he has had hair removed from his back, possibly from his buttocks. He has no hair at all except on his face, his head. And he has pubic hair. He mentioned Demerol to me. If someone came in with scrubs and a mask on, and Oscar was on his belly, he would never have seen the tech or necessarily recognize him later. At Terri’s apartment, for example, when Morales encountered Oscar at the crime scene? Oscar wouldn’t necessarily connect him with some backroom tech at Dr. Stuart’s office.”

“In the video, we think Terri calls him Juan. We’re not sure. You need to listen,” Berger said.

Scarpetta said, “They’re doing R-and- D with wireless GPS glass-encapsulated chips that have miniature antennas and a power supply that can last up to three months. About the size of a grain of rice, maybe smaller. One of them could have been implanted into his buttocks and he’d never know, especially if it’s migrated, buried itself in deeper, which happens. We could find it with an x-ray, if we can find him. And by the way, he’s not the only one paranoid about this sort of thing. The U.S. government has a number of pilot programs, and a lot of people fear that mandatory chipping is on the horizon.”

“Not me,” Berger said. “I’ll move.”

“You’ll have plenty of company. That’s why some call it Mark of the Beast Six-Six- Six technology.”

“But you didn’t see anything like that in Terri’s x-rays?”

“I’ve been looking,” Scarpetta said. “I have the electronic files of that and everything else, and I’ve been doing nothing but work on all of this since we last spoke. The answer’s no. It’s very important that Dr. Lester get more films, and I want to see them. Especially focusing on the back, the buttocks, the arms. People who have been implanted with microchips usually get them in their arms. Morales would know a lot about microchip technology for the simple reason it’s used to tag animals. He would have seen microchips implanted in pets at the vet’s office. He may have done the implanting himself, a simple procedure that requires nothing more than the chip and an implant gun fitted with a fifteen-gauge needle. I can be there in maybe half an hour.”

“That would be fine.”
